Hair Treating Compositions Containing Cationic Surface Active Agents

The present invention relates to cationic surface active agents which are the condensation products of an alcohol having the formula ROH with (a) glycerol epihalohydrin or (b) an epoxide and glycerol epihalohydrin.

In accordance with this embodiment of the present invention there are provided cationic surface active agents selected from the group consisting of

1. agents having the formula ##STR1## which are hydroxylated condensation products of an alcohol having the formula ROH and glycerol epihalohydrin wherein R is a hydrophilic group selected from the class consisting of linear or branched alkyl and alkenyl having 8-22 carbon atoms, and alkylphenyl having 8-22 carbon atoms, R.sub.1 and R.sub.2 each independently are selected from the group consisting of lower alkyl having 1-4 carbon atoms and hydroxy lower alkyl having 1-4 carbon atoms or together with the nitrogen atom to which they are attached form a ring selected from the group consisting of morpholine and piperidine and n is 0.5-10; and

2. agents which are the quaternary ammonium salts of (1) having the formula ##STR2## where n, R, R.sub.1 and R.sub.2 have the meaning given above, R.sub.3 is selected from the group consisting of methyl and ethyl, and Y is an anion selected from the group consisting of Cl, Br, I, SO.sub.4 CH.sub.3, SO.sub.4 C.sub.2 H.sub.5, CH.sub.3 SO.sub.3 and ##STR3##

The cationic surface active agents of this embodiment of the invention are prepared by

a. condensing on a fatty alcohol or on an alkyl phenol having the formula ROH wherein R has the meaning given above (n+1) moles of glycerol epihalohydrin having the formula ##STR4## wherein n has the meaning given above and X is halogen, preferably chlorine or bromine to form a mixture of polyhalogenated polyethers having the formula

b. dehydrohalogenating said polyhalogenated polyethers from step (a) with an alkali metal hydroxide or an alkaline earth metal hydroxide to form a mixture of polyhalogenated glycidyl ethers having the formula ##STR5## c. reacting the polyhalogenated glycidyl ethers from step (b) with a secondary amine to form a mixture of polyhalogenated tertiary amines having the formula ##STR6## and d. replacing the halogen by a hydroxyl in the polyhalogenated tertiary amines from step (c) to form a mixture of polyhydroxylated tertiary amines having formula (I) given above.

The various steps in the above process for preparing the surface active agents represented by formula (I) are as follows: ##STR7##

The quaternization of the surface active agents represented by formula I yields quaternary ammonium salts having the formula ##STR8## wherein R, R.sub.1, R.sub.2, R.sub.3, Y.sup.- and n have the meaning given above.

In the course of the condensation reaction (a) above, when the epoxy ring is opened during the polycondensation, a mixture of compounds comprising the structures ##STR9## is obtained.

Thus a mixture of compounds having the general structure --C.sub.2 H.sub.3 (CH.sub.2 X)O-- is obtained. Consequently, the hydroxylated compound of formula I and II given above represents the two isomers ##STR10## and the corresponding two isomers of the quaternary ammonium salts.

In the above formulae n is defined by the equation: ##EQU1## wherein M is equal to the molecular weight of the alcohol or alkyl phenol ROH, E is equal to the molecular weight of the glycerol epihalohydrin and I is the hydroxyl index of the condensation product, i.e., the mixture of polyhalogenated polyethers represented by formula (III) above, after step (a).

During the condensation reaction (a) in which (n+1) moles of glycerol epihalohydrin are reacted on one mole of alcohol or alkyl phenol, the number of moles of glycerol epihalohydrin fixed by one mole of alcohol or alkyl phenyl to form the recurring units, --C.sub.2 H.sub.3 (CH.sub.2 X)O], can be greater or smaller than the value of n and a mixture of compounds, all responding to the general formula III are formed, but in which the number of recurring units varies and all those different numbers are distributed statistically around a mean value represented by n. Consequently, n in the final product represents the mean value or the average statistical value of the number of recurring units, --C.sub.2 H.sub.3 (CH.sub.2 OH)O], fixed on the different compounds having the general formula I or II.

An important fact which should be emphasized and which constitutes one of the essential advantages of the process of preparing the surface-active agents of this invention is that the present process results in the formation of compounds having a single lipophilic chain per hydrophilic chain.

Moreover, the process of the present invention permits the regulation of the hydrophilic and lipophilic properties of the final product. The hydrophilic characteristic of the resulting surface active agents can be regulated by choosing the value of the number n of moles of glycerol epihalohydrin to be reacted with one mole of fatty alcohol or alkyl phenol. The lipophilic characteristic of the resulting surface active agents can be regulated by choosing the length of the hydrocarbon chain R in the fatty alcohol or alkyl phenol used as an initial reactant.

The following is a detailed description of a preferred embodiment of producing the above surface-active agents.

In step (a), the condensation of glycerol epichlorohydrin or glycerol epibromohydrin on the fatty alcohol or alkyl phenol is carried out in the presence of an acid catalyst, such as boron trifluoride, stannic chloride or antimony pentachloride, at a temperature between 25.degree.-160.degree. C. Preferably boron trifluoride is employed at a temperature between 60.degree.-120.degree. C. The proportion of BF.sub.3 with respect to the total mass of reactants ranges between 0.1-0.2 weight percent.

In step (b), the polyhalogenated polyethers, represented by formula (III) above, which result from step (a), are converted to glycidyl ethers (Formula IV) by dehydrohalogenation of the halohydrin, using an aqueous solution of an alkali or alkaline earth metal hydroxide, having a concentration, by weight, of from 20-50 percent. The molar ratio of alkali or alkaline earth metal hydroxide to polyhalogenated polyether ranges between 1:1 to 1:2 and preferably between 1:1.2 to 1:1.5. During this phase of the overall process, which ordinarily is initially conducted at about 20.degree. C or ambient temperature, the reaction temperature rises to about 100.degree. C. When the exothermicity of the reaction ceases, the reaction is terminated by heating the reaction mixture in a water bath. This dehydrohalogenation operation is generally conducted in the presence of a solvent to obtain high reaction speeds and high epoxidation yields. The solvent employed should, preferably, not be miscible with concentrated aqueous solutions of electrolytes so that the resulting polyhalogenated glycidyl ethers can be separated from the reaction medium simply by decantation. Tertiary butyl alcohol and 2-butoxy ethanol are particularly useful solvents when used in weight proportions essentially equal to that of the halohydrin to be dehydrohalogenated. Quaternary ammonium salts comprising a lipophilic chain can be used to improve the contact between the reactants. The resulting polyhalogenated glycidyl ether, if desired, can be isolated by evaporation of the solvent or it can be used in solution in the subsequent stage, i.e., step (c).

In step (c), the polyhalogenated glycidyl ethers from step (b) are reacted with a secondary amine at a temperature from 25.degree.-120.degree. C to open the epoxide ring and thereby form the polyhalogenated tertiary amines having formula (IV).

Alternatively, the polyhalogenated tertiary amines of formula (IV) can be prepared in a single step by reacting the polyhalogenated polyethers from step (a) with a secondary amine in the presence of an alkali or alkaline earth metal hydroxide.

Representative secondary amines usefully employed in the present invention include diethylamine, dipropylamine, morpholine, piperidine and alkanolamines such as diethanolamine, diisopropanolamine/diglycerylamine and N-ethylethanolamine.

The molar ratio of secondary amine to polyhalogenated glycidyl ether in step (c) or the ratio of secondary amine to polyhalogenated polyether (when the alternate route is practiced) to produce polyhalogenated tertiary amines is between about 1:1 to 1:1.5 and, preferably, about 1:1.2.

In step (d), the replacement of the halogen by a hydroxyl in the polyhalogenated tertiary amine from step (c), or from its alternate route, yields the polyhydroxylated amines of the present invention which are useful surface active agents and which are represented by formula I. This operation is carried out with an alkaline salt of a carboxylic acid, such as sodium or potassium acetate, at a temperature between 150.degree.-200.degree. C, preferably about 180.degree. C, in the presence or absence of a solvent.

The presence of a solvent in the reaction medium during step (d) assures both instantaneous and progressive contact among the reactants and easy separation therefrom of the mineral halide formed. Suitable solvents include ethylene glycol, diethylene glycol, propylene glycol, dipropylene glycol as well as the monoalkylethers of these diols such as, monobutyl ether of ethylene glycol and monobutyl ether of diethylene glycol. The hydroxylated solvents also intervene by alcoholysis of the esters formed in an intermediate step.

When the reaction is carried out in the absence of a solvent, as may be the case when the alkaline salt of carboxylic acid is somewhat soluble in the reaction medium, the polyhydroxylated tertiary amine is obtained by alcoholysis of the esters of carboxylic acid with a lower alcohol such as methanol or ethanol, or by saponification followed by salting out or extraction.

In one preferred commercial exploitation of the present invention, the polyhalogenated polyethers from step (a) are reacted with a secondary amine, as defined above, in the presence of an alkali or alkaline earth metal hydrooxide, without isolating the glycidyl ethers thus formed. After reaction with an alkaline salt of carboxylic acid, the esterified amino ethers are separated from the mineral halide by filtration or washing, and then the salts of carboxylic acid are regenerated in situ from the carboxylic esters by saponification with an alkaline hydroxide. Thus, the alkaline salt of carboxylic acid is recovered in aqueous solution and can be used for another hydroxylation reaction.

As stated above, the surface-active agents of this embodiment of the present invention also include the quaternary ammonium salts of the compounds represented by formula I, the quaternary ammonium salts being represented by formula II. To produce said quaternary ammonium salts, the compounds represented by formula I can be reacted with, for instance a quaternizing agent such as methyl sulfate, ethyl sulfate, ethyl chloride, ethyl bromide, methyl iodide, methyl paratoluylene sulfate or methyl methane sulfonate. The mole ratio of quaternizing agent to the compounds represented by formula I corresponds to the stoichiometric amount or is slightly inferior and the reaction is carried out at a temperature ranging from about 15.degree. to 100.degree. C at atmospheric pressure.

Compared, for example, with fatty amines, the surface active agents of the present invention are significantly more water soluble especially at about neutral pH and they lack the odor characteristic of fatty amines and derivatives thereof.

Additionally, the process of the present invention yields stable surface-active agents which are soluble in water over a very wide pH range. The present process also provides surface-active agents which are soluble in concentrated sodium hydroxide without risk of instability which occurs, for example, with the quaternary ammonium hydroxides. Moreover, this result is obtained without the introduction of supplementary ionic groups, and especially anionic groups, which impair the substantive characteristics of the surface-active agents. The solubility characteristics of the surface-active agents of this invention are, of course, highly variable as a function of the values of n, R, R.sub.1, and R.sub.2. Certain of these agents in which R represents alkyl or alkaryl and in which n is equal to 5-6 are soluble in sodium hydroxide. The extent to which these surface-active agents may irritate the skin and mucous membranes is also dependent on the values of n, R, R.sub.1 and R.sub.2. In general, however, the surface-active agents of this invention are clearly less irritating than fatty amines and their derivatives.

The surface active agents of the present invention also provide advantages not secured by such prior art compounds as those disclosed in Luxembourg application No. 48,458 filed Apr. 23, 1965 which are non-ionic surface-active agents having the formula RO-C.sub.2 H.sub.3 (CH.sub.2 OH)O].sub.n H

In contradistinction, the surface-active agents of the present invention contain a hydroxy amino propane group ##STR11## which imparts thereto their cationic characteristics and their substantivity, i.e., their affinity for fibers and particularly for animal and vegetable fibers.

The surface-active agents of the present invention also compare favorably with amino polyethers having the formula ##STR12## and the substitution of a--C.sub.2 H.sub.3 (CH.sub.2 OH)O] group for the oxyethylene group --OCH.sub.2 CH.sub.2) is very useful.

Examples 19-28 which illustrate the preparation of additional surface active agents in accordance with this embodiment of the present invention are set forth below in Table I.

In accordance with this embodiment of the present invention there are provided cationic surface-active agents selected from the group consisting of:

1. agents having the formula: ##STR53## which are hydroxylated condensation products of an alcohol having the formula R'OH, an epoxide having the formula ##STR54## and glycerol epihalohydrin, wherein R' is a hydrophilic group selected from the class consisting of linear or branched alkyl and alkenyl having 12-20 carbon atoms, R" represents a member selected from the group consisting of methyl and ethyl, m has a statistical average value of 2-6, R.sub.1 and R.sub.2 each independently are selected from the group consisting of lower alkyl having 1-4 carbon atoms, lower hydroxyalkyl having 1-4 carbon atoms or together with the nitrogen atom to which they are attached form a ring selected from the group consisting of morpholine and piperidine and n has a statistical average value of 0.5-4; and

2. agents which are the quaternary ammonium salts of (1) having the formula ##STR55## wherein R', R", R.sub.1, R.sub.2, m and n have the meaning given above, R.sub.3 is selected from the group consisting of methyl and ethyl and Y is an anion selected from the group consisting of Cl, Br, I, SO.sub.4 CH.sub.3, SO.sub.4 C.sub.2 H.sub.5, CH.sub.3 SO.sub.3 and

The cationic surface active agents of this embodiment of the present invention are prepared by

a. condensing on a fatty alcohol having the formula R'OH wherein R' has the meaning given above, m moles of an epoxide or mixture of epoxides having the formula ##STR56## wherein R" has the meaning given above to form a compound having the formula

b. condensing on the compound represented by formula VIII, (n+1) moles of glycerol epihalohydrin having the formula ##STR57## wherein n has the meaning given above and X is halogen, preferably chlorine or bromine to form a mixture of polyhalogenated polyethers having the formula

c. dehydrohalogenating said polyhalogenated polyethers from step (b) with an alkali metal or an alkaline earth metal hydroxide to form a mixture of polyhalogenated glycidyl ethers having the formula ##STR58## d. reacting the polyhalogenated glycidyl ethers from step (c) with a secondary amine to form a mixture of polyhalogenated tertiary amines having the formula ##STR59## and e. replacing the halogen by hydroxyl in the polyhalogenated tertiary amines from step (d) to form a mixture of polyhydroxylated tertiary amines having formula VI given above.

The various steps in the above process for preparing the surface active agents represented by formula VI are as follows: ##STR60##

The quaternization of the surface-active agents represented by formula VI yields quaternary ammonium salts having the formula ##STR61## wherein R', R", R.sub.1, R.sub.2, R.sub.3, Y.sup.-, m and n have the meaning given above.

In the course of the condensation reaction (a) and (b) above, when the epoxy ring is opened during the polycondensation, a mixture of compounds comprising the structure ##STR62## is obtained.

Thus a mixture of compounds having the general structure --C.sub.2 H.sub.3 (CH.sub.2 X)O-- is obtained. Consequently, the hydroxylated compound of formulae VI and VII given above represents four isomers of each, two of which result from the opening of the epoxide ##STR63## the other two resulting from the epoxide group of the glycerol epihalohydrin.

In the above formulae m is defined by the equation: ##EQU2## wherein M' is equal to the molecular weight of the alcohol R'OH, E' is equal to the molecular weight of the epoxide ##STR64## and I' is the hydroxyl index of the condensation product, i.e., the compound represented by formula VIII above, after step (a).

In the same formula above, n is defined by the equation: ##EQU3## wherein M is equal to the molecular weight of the alcohol of formula VIII, E is equal to the molecular weight of the glycerol epihalohydrin and I is the hydroxyl index of the condensation product, i.e., the mixture of polyhalogenated polyethers represented by formula IX, after step (b).

During the condensation reaction (a) in which m moles of the epoxide having formula ##STR65## which epoxide can be for instance propylene oxide and/or butylene oxide, are reacted on one mole of alcohol having the formula R'OH, the number of moles of epoxide fixed by one mole of alcohol to form the recurring units -- C.sub.2 H.sub.3 (R")O] can be greater or smaller than the value m and a mixture of compounds, all responding to general formula VIII are formed, but in which the number of recurring units varies and all those different numbers are distributed statistically around a mean value represented by m. Consequently m in the final product represents the mean value or the average statistical value of the number of recurring units -- C.sub.2 H.sub.3 (R")O] fixed on the different compounds having the general formula (VI) or VII.

During the condensation reaction (b) in which (n+1) moles of glycerol epihalohydrin are reacted on one mole of alcohol R"O -- C.sub.2 H.sub.3 (R")O] H designated as formula VIII the number of moles of glycerol epihalohydrin fixed by one mole of alcohol VIII to form the recurring units -- C.sub.2 H.sub.3 (CH.sub.2 OH)O] can be greater or smaller than the value n and a mixture of compounds, all responding to general formula IX are formed, but in which the number of recurring units -- C.sub.2 H.sub.3 (CH.sub.2 OH)O] varies and all those different numbers are distributed statistically around a mean value represented by n. Consequently n in the final product represents the mean value or the average statistical value of the number of recurring units -- C.sub.2 H.sub.3 (CH.sub.2 OH)O] fixed on the different compounds having the general formula VI or VII.

An important fact which should be emphasized and which constitutes one of the essential advantages of the process of preparing the surface-active agents of this invention is that the present process results in the formation of compounds having a single lipophile chain per hydrophile chain.

Moreover, the process of the present invention permits the regulation of the hydrophilic and lipophilic properties of the final product. The hydrophilic characteristic of the resulting surface-active agents can be regulated by choosing the value of the number n of moles of glycerol epihalohydrin reacted with one mole of fatty alcohol. The lipophilic characteristics of the resulting surface-active agents can be regulated by choosing the length of the hydrocarbon chain R in the fatty alcohol.

The following is a detailed description of a preferred embodiment of producing the above surface-active agents.

In steps (a) and (b), i.e., the condensation of propylene and/or butylene oxide on one hand and of glycerol epichlorohydrin or epibromohydrin on the other hand, are carried out, one after the other, in the presence of an acid catalyst such as boron trifluoride, stannic chloride or antimony pentachloride, at a temperature of between 25.degree. and 160.degree. C and preferably between 60.degree. and 120.degree. C if boron trifluoride is used. The proportion of BF.sub.3 with respect to the total mass of the reactants is between 0.1 and 1% by weight.

In step (c) the polyhalogenated polyethers represented by formula (IX) above, which result from step (b), are converted to glycidyl ethers (formula X) by dehydrohalogenation of the halohydrin, using an aqueous solution of an alkali or alkaline earth metal hydroxide, having a concentration, by weight, of from 20 to 50%. The molar ratio of alkali or alkaline earth metal hydroxide to polyhalogenated polyethers ranges between 1:1 and 1:2 and preferably from about 1:2.2 to 1:1.5. During this phase of the overall process, which ordinarily is initially conducted at about 20.degree. C or ambient temperature, the reaction temperature rises to about 100.degree. C. When the exothermicity of the reaction ceases, the reaction is terminated by heating the reaction mixture in a water bath. This dehydrohalogenation operation is generally conducted in the presence of a solvent to obtain high reaction speeds and high epoxidation yields. The solvent employed should preferably, not be miscible with concentrated aqueous solutions of electrolytes so that the resulting polyhalogenated glycidyl ethers can be separated from the reaction medium simply by decantation. Tertiary butyl alcohol and 2-butoxy ethanol are particularly useful solvents when used in weight proportions essentially equal to that of the halohydrin to be dehydrohalogenated. Quaternary ammonium salts comprising a lipophile chain can be used to improve the contact between the reactants. The resulting polyhalogenated glycidyl ethers if desired, can be isolated by evaporation of the solvent or it can be used in solution in the subsequent stage, i.e., step (d).

In a step (d) the polyhalogenated glycidyl ethers from step (c) are reacted with a secondary amine at temperatures of from 25.degree. to 120.degree. C to open the epoxide ring and thereby from the polyhalogenated tertiary amines having formula XI.

Alternatively the polyhalogenated tertiary amines of formula XI can be obtained in a single step by reacting the polyhalogenated polyethers from step (b) directly with a secondary amine in the presence of an alkali or alkaline earth metal hydroxide.

Representative secondary amines usefully employed in the present invention include diethylamine, dipropylamine, morpholine, piperidine, and alkanolamines such as diethanolamine, diisopropanolamine, diglycerylamine and N-ethylethanolamine.

The molar ratio of secondary amine to epoxide (when the glycidyl ethers responding to formula IX are isolated) and the molar ratio of secondary amine: halohydrin (when the secondary amine is reacted directly without isolating the glycidyl ethers responding to formula IX) are between about 1:1 and 1:1.5, the preferred ratio being about 1:1.5.

In step (e) the replacement of the halogen by a hydroxyl in the polyhalogenated tertiary amine from step (d), or from its alternate route, yields the polyhydroxylated amines of the present invention which are useful surfaceactive agents and which are represented by formula VI. This operation is carried out with an alkaline salt of carboxylic acid, such as sodium or potassium acetate, at a temperature of between 150.degree.and 200.degree. C, preferably, about 180.degree. C, in the presence or absence of a solvent.

The presence of a solvent in the reaction medium during step (e) assures both instantaneous and progressive contact among the reactants and easy separation therefrom of the mineral halide formed. Suitable solvents include ethylene glycol, diethylene glycol, propylene glycol, dipropylene glycol, as well as the monoalkylethers of these diols, such as monobutyl ether of ethylene glycol and monobutyl ether of diethylene glycol. The hydroxylated solvents also intervene by alcoholysis of the esters formed in an intermediate step.

When the reaction is carried out in the absence of a solvent, as may be the case when the alkaline salt of carboxylic acid is somewhat soluble in the reaction medium, the polyhydroxylated tertiary amine is obtained by alcoholysis of the esters of carboxylic acid with a lower alcohol such as methanol or ethanol, or by saponification followed by salting out or extraction.

In one preferred commercial embodiment, the polyhalogenated polyethers from steps (a) and (b) are reacted with a secondary amine, as defined above in the presence of an alkali or alkaline earth metal hydroxide, without isolating the glycidyl ethers thus formed. After reaction with an alkaline salt of carboxylic acid, the esterified amino ethers are separated from the mineral halide by filtration or washing, and then the salts of carboxylic acid are regenerated in situ from the carboxylic esters by saponification with an alkaline hydroxide. Thus, the alkaline salt of carboxylic acid is recovered in aqueous solution and can be used for another hydroxylation reaction.

As stated above, the surface-active agents of this embodiment of the present invention also include the quaternary ammonium salts of the compounds represented by formula VI, the quaternary ammonium salts being represented by formula VII. To produce said quaternary ammonium salts, the compounds represented by formula VI can be reacted with, for instance, a quaternizing agent such as methyl sulfate, ethyl sulfate, ethyl chloride, ethyl bromide, methyl iodide, methyl paratoluylene sulfate or methyl methane sulfonate. The mole ratio of quaternizing agent to the compounds represented by formula VI corresponds to the stoichiometric amount or is slightly inferior and the reaction is carried out at a temperature ranging from about 15 to 100.degree. C at atmospheric pressure.

Compared, for example, with fatty amines, the surface-active agents of this embodiment of the present invention lack the odor characteristic of fatty amines and their derivatives, have a low melting point, are saturated and consequently do not become rancid.

Additionally, the process of the present invention yields stable surface-active agents which are soluble in water without the introduction of supplementary ionic groups, and especially anionic groups which impair the substantive characteristics of the surface-active agents. Further, the surface-active agents of this invention are considerably less irritating to the skin and to mucous membranes than are the fatty amines and their derivatives.

The surface-active agents of the present invention also compare favorably with amino polyethers having the formula ##STR66## and the substitution of a-- C.sub.2 H.sub.3 (CH.sub.2 OH)O] group for the oxyethylene group --OCH.sub.2 CH.sub.2) is very useful.

The surface-active agents of this invention, because of their physical and chemical characteristics, are suitably employed in cosmetic preparations, shampoos, permanent waving compositions and particularly in hair dye and hair rinse compositions. Further, when the surface active agents of this embodiment of the present invention, and especially those represented by formula VI are used in compositions for treating hair, they impart to the hair a certain sheen and a pleasing texture. The hair is particularly soft, odorless and is easily untangled.

Thus, in accordance with the present invention there is provided a shampoo composition comprising an aqueous solution of the surface active agents of this invention present in amounts of about 0.5 to 6 percent by weight of said shampoo composition, having a pH ranging from about 3 to 6.5. The pH can be adjusted to the desired value by incorporating into said composition an acidic component such as lactic, acetic or citric acid and the like.

In another embodiment of the present invention hair is permanently waved by applying to the hair wound on curlers during the first stage, i.e., during the reducing stage, a composition comprising reducing agent, permitting the composition to remain on the hair for a time sufficient to alter the disulphide bonds of the keratin of the hair, generally about 10-40 minutes, thoroughly rinsing the hair to remove residual reducing agent and applying in the second stage, i.e., during the neutralization stage, a cosmetic composition comprising a mixture of an oxidizing or neutralizing agent and the surface-active agent of the present invention, whereby the disulphide bonds of the keratin of the hair are reformed.

Conventional reducing agents employed are advantageously those organic thiols which are generally used to perform the first stage of a permanent waving operation. Representative thiols include thioglycolic acid and its salts, glycol thioglycolate, glycerol thioglycolate, thioglycolic amide, thiolactic acid, glycol thiolactate, .beta.-mercaptoethanol, N-carboxymethyl mercapto acetamide, .beta.-mercapto propionic acid, and the like. Generally the composition comprising the reducing agent is an aqueous solution of said reducing agent present in amounts of about 2 to 15 percent by weight thereof and having a pH ranging from about 8 to 10.

The neutralizing composition of the present invention comprises an aqueous solution of 0.5 to 4 weight percent of a conventional neutralizing or oxidizing agent and about 0.2 to 15 weight percent of the surface-active agent of this invention. Conventional neutralizing agents employed include, for instance, hydrogen peroxide, sodium or potassium bromate, sodium perborate or percarbonate and the like.

The surface-active agents of the present invention are also usefully employed in hair dye compositions comprising a solution in a solvent selected from the group consisting of water and an aqueous solution of a lower alkanol such as ethanol and isopropanol, of a glycol such as butyl glycol, propylene glycol, ethylene glycol, 3-amyloxy 4-propane 1,2-diol and of a monoalkyl ether of glycol such as monobutyl ether of ethylene glycol wherein said alkanol and/or glycol and/or ether of glycol is present in amounts of about 8 to 25 percent by weight of said solution, a hair dye such as azo, anthraquinone and nitro dyes of the benzene series, and 0.5 to 6 percent by weight of the surface-active agent of the present invention.

Additionally, if desired, said hair dye composition can include its weight of hydrogen peroxide to provide said composition in gel form.

Preparation of a mixture of surface-active agents having the formula ##STR67## wherein R' is octadecyl, m has a statistical average value of 5.25 and n has a statistical average value of 1.

6.25 ml of an acetic acid complex of boron fluoride at 36% BF.sub.3 are added to a molar equivalent quantity of industrial stearoyl alcohol (hydroxyl index: 195 mg KOH/g) dehydrated by heating in a boiling water bath in a vacuum and melted.

The mixture is heated to 75.degree.-80.degree. C. Then 5.25 moles of propylene oxide are added drop by drop, the rate of flow being regulated so that the temperature stays between 75.degree.-80.degree. C because of the exothermic nature of the reaction. When the propylene oxide has been completely used up, which is determinated by measurement of the epoxide function in a sample withdrawn for the purpose, 2 moles of glycerol epichlorohydrin are added drop by drop. The temperature is kept constant as before by regulating the rate of addition. The polychlorinated polyether having the following formula is obtained:

wherein R', m and n have the meaning given above, the said polyether having a theoretical hydroxyl index of 73.5 (found 90) mg KOH/g.

177 g of diisopropanolamine, then 143 g of a 40% sodium hydroxide solution are added to 776 g of the above polychlorinated polyether.

When the reaction ceases to be exothermic, the mixture is heated to 90.degree.-95.degree. C for 3 hours.

A mixture of polychlorinated tertiary amines having the following formula is thus obtained: ##STR68## wherein R', m and n have the meaning given above.

The excess sodium hydroxide is neutralized with 8 ml of anhydrous acetic acid. 800 ml of butyl monoether of diethylene glycol and 108 g of potassium acetate are added. After the water has been removed, the mixture is heated to 180.degree.-185.degree. C for 5 hours.

After cooling to 95.degree. C, 1.8 liters of hot water are added, the mixture is stirred and decanted and the aqueous phase containing the sodium chloride which has formed is drawn off.

The water and solvent are evaporated from the organic phase by progressively raising the temperature to 180.degree. C under a pressure of 15 to 20 mm of mercury.

An oily yellow product is obtained which is soluble in warm at a pH of 3 (the pH being adjusted with lactic acid). Its formula is given at the top of this example.

This product can also be obtained with the same results by using the same reactant in the same proportions, but no solvent. In this case, the product is de-acetylated by saponification, then separated by salting out.

The procedures of Example 29 are repeated except that comparably equivalent amounts of butylene oxide are employed in steps (a) and (b) rather than propylene oxide.

C; and butylene oxide, respectively, to produce the following polychlorinated polyether,

wherein R', m and n have the meaning given above.

Then, 36.5 g of morpholine and 44 g of a 40% aqueous solution of sodium hydroxide are added to 222 g of the above polychlorinated polyether. The addition of the sodium hydroxide takes 15 minutes and the resulting mixture is then heated in a water bath for three hours. A polychlorinated tertiary amine having the following formula is thus obtained, ##STR70##

The excess sodium hydroxide is neutralized with 2.4 g of glacial acetic acid and the reaction mixture is diluted with an equivalent weight of dipropylene glycol. Then 35 g of anhydrous potassium acetate are added and the mixture is heated to 180.degree.-185.degree. C for five hours after the water has been removed.

After evaporation of dipropylene glycol under reduced pressure, the de-acetylation is completed by saponification using 5 g of an aqueous 40% solution of sodium hydroxide. It is then washed twice with 250 ml of boiling water and the organic phase is then dehydrated by being heated in a vacuum. 211 g of a red-brown oil, having the formula given at the beginning of the example, are collected.

C because of the exothermic nature of the reaction. When the propylene oxide has been completely used up, which is determined by measurement of the epoxide function is a sample withdrawn for the purpose, 1 mole (92.5 g) of glycerol epichlorohydrin is added drop by drop. The temperature is kept constant as before by regulating the rate of addition. The polychlorinated polyether having the following formula is obtained:

wherein R', m and n have the meaning given above, the said polyether having a theoretical hydroxyl index of 73 mg KOH/g.

22.5 g of diethanolamine, then 22 g of a 40% sodium hydroxide solution are added to 0.2 mole (103 g) of the above polychlorinated polyether.

When the reaction ceases to be exothermic, the mixture is heated to 90.degree.-95.degree. C for 2 hours.

A mixture of polychlorinated tertiary amines having the following formula is thus obtained: ##STR72## wherein R', m and n have the meaning given above.

110 g of dipropylene glycol and 44 g of potassium acetate are added. After the water has been removed, the mixture is heated to 180-185.degree. C for 4 hours.

After letting the setting agent act for a certain time, and rinsing, the hair is in very good shape, it untangles easily, is soft, and there is no foam left in it. These improvements in rinsing are due to the presence of the mixture of the compounds which is the object of the present invention and to the fact that this mixture of compounds is highly hydrophilic due to the increase in the value of n from 0.5 to 1.

After using the same permanent waving composition as before, the following solution is applied as a fixative:

wherein R is a straight chain alkyl having 12 to 14 carbon atoms and n has a statistical average value of 0.5.
