Description
The present invention relates to new sequenced oligomer surfactants of the polyhydroxylated polyether type; to a process for their preparation; to their use; and to polyhalogenated polytertiobutoxy intermediates as well as polyhalogenated polyhydroxylated intermediates.
A significant number of surface active agents are presently known whose structure exhibits a lipophilic chain and a hydrophilic chain, wherein the lipophilic chain is constituted by a fatty aliphatic or aryl-aliphatic hydrocarbon chain having from 8 to 18 carbon atoms. These products have found numerous uses in the most varied fields. They exhibit a variety of structures although it has been found that their properties are limited by the nature of the lipophilic portion thereof.
In order to overcome this disadvantage, it has been proposed to replace the hydrocarbon chain of conventional surfactants by a lipophilic sequence obtained from the polymerization of an alkylene oxide having at least three carbon atoms.
This concept has been disclosed in U.S. Pat. No. 2,677,700 and in accordance with a preferred embodiment of the invention disclosed therein, the lipophilic sequence is a polyoxpropylene chain and the hydrophilic sequence is a polyoxyethylene chain.
According to U.S. Pat. No. 3,454,646, the polyoxyethylene chain is replaced by a sequence selected from (dialkyl amino-methyl)-ethyleneoxy or (N-oxydialkyl amino-methyl)-ethyleneoxy; the lipophilic sequence being obtained by the reaction of a lower alkylene oxide with a monoalcohol or a polyol.
It is also generally known that the surface activity of an amphiphile compound increases with the length of the lipophile chain. The works of T. Kuwanura (Kobunshi Kagaku 17, pp. 175-182, 1960) have shown that in the case of polymer sequences produced from alkyl glycidyl ethers and ethylene oxide, this rule is confirmed.
However, until now, it has not been possible to obtain sequence structured polyethers having, simultaneously high surface activity and satisfactory water-solubility characteristics.
The present invention provides products which possess in combination the following advantageous properties: surface activity, affinity for water, chemical stability and weak mucous aggressiveness.
Thus, the present invention relates to bisequenced and trisequenced oligomer surfactants of the formulas A-B and A-B-A', respectively. These surfactants can be represented by the general formula: ##STR1## wherein R represents linear alkyl having 4-18 carbon atoms and having, preferably an even number of carbon atoms;
Z represents a member selected from ##STR2## wherein R.sub.1 and R.sub.2 each independently represent methyl, ethyl or hydroxyethyl;
X.sup..crclbar. represents Cl.sup..crclbar. or Br.sup..crclbar. ;
y.sup..crclbar. represents an anion and, preferably chloride, bromide, iodide, methyl sulfate, methane sulfonate or paratoluene sulfonate;
Hr.sub.1 n.sup.+ v.sup.- and R.sub.1 NO.sup.+ HV.sup.- represent mineral or organic salts of an amine or amine oxide, and preferably a hydrochloride, hydrobromide, sulfate, phosphate, acetate, lactate, tartrate, oxalate or succinate;
a represents 0 or 1;
--C.sub.2 H.sub.3 (CH.sub.2 OH)O-- represents the two isomers; ##STR3## --C.sub.2 H.sub.3 (CH.sub.2 ZR)O-- represents the two isomers; ##STR4## m represents a whole or decimal number from 2 to 10; n represents a whole or decimal number from 2 to 25;
n' represents O or a whole or decimal number from 2 to 25; and
the sum n + n' represents a whole or decimal number from 2 to 25.
The values m, n and n' are numbers corresponding to statistical averages and represent the degrees of polymerization; the actual number of units for each sequence in a given compound being lower or higher than the statistical average.
The present invention also relates to a three stage process for preparing the bisequenced compounds of formula (I) of the type, A-B (n' = 0) and the trisequenced compounds of the type A-B-A' (n' .noteq. 0 and n + n' = 2-25).
In the preparation of a bisequenced oligomer surfactant, this process comprises the following steps:
(1) In a first stage an intermediate oligomer is prepared by the telomerization of tertio-butyl glycidyl ether on a tertio-butyl alcohol followed by the telomerization of an epihalohydrin such as epichlorhydrin or epibromhydrin on the previously obtained telomer, which serves as the telogen, according to the following reactions: ##STR5##
In these reactions T represents the tertiobutyl group, ##STR6## X represents Cl or Br; the unit --C.sub.2 H.sub.3 (CH.sub.2 OT)O-- represents the two isomers: ##STR7## and the unit --C.sub.2 H.sub.3 (CH.sub.2 X)O-- represents the two isomers: ##STR8##
In the preparation of a trisequenced oligomer surfactant, the intermediate compound of formula (II), is telomerized with n' moles of tertiobutyl glycidyl ether according to the reaction: ##STR9##
These telomerization reactions are carried out at a temperature from 50 to 110.degree. C. and preferably from 60 to 80.degree. C., in the presence of a Lewis acid catalyst, and preferably in the presence of boron trifluoride, tin tetrachloride or antimony pentachloride.
The weight amount of catalyst relative to the reaction mass is from 0.1-3 percent, and preferably from 0.2 to 1.5%.
The catalyst is introduced preferably in fractions to avoid having too high a concentration thereof at the beginning of the polymerization reaction.
Generally, the catalyst and the epoxide group containing compound for each of the sequences being prepared are added alternately in portions (from one to four).
After the telomerization reaction, the reaction mass is washed with water, in the presence of a sufficient amount of basic compound which is preferably, sodium hydroxide, to neutralize the catalyst. After drying under reduced pressure, the volatile compounds are generally removed by molecular distillation.
The molecular weight of the intermediate compounds is between 500 and 5,000 and generally between 800 and 3,000.
(2) In a second stage the tertiobutoxy groups, (OT), are replaced by OH groups in the presence of an acid catalyst and preferably in the presence of a sulfocarboxylic acid at a temperature of 80-110.degree. C. for 1-4 hours. The replacement of the tertiobutoxy groups by OH groups is described more fully in French Pat. No. 2,027,585 and U.S. Pat. No. 3,840,606, incorporated herein by reference.
(3) In a third stage the halogen substituent X is replaced by a group selected from: ##STR10## wherein R, R.sub.1, R.sub.2, X.sup..crclbar., Y.sup..crclbar., RR.sub.1 N.sup..sym. HV.sup..crclbar., RR.sub.1 NO.sup..sym. HV.sup..crclbar. and a have the meanings given above. Step 3 can be accomplished in the following alternative ways:
(3a) by reaction of the halogenated telomer with a secondary amine, optionally followed by oxidation and/or salification or betainization; or (3b) by reaction of the halogenated telomer with a tertiary amine; or
(3c) by reaction of the halogenated telomer with an alkaline alkyl mercaptide and preferably with a sodium or potassium alkyl mercaptide; it being understood that the order of stages 2 and 3 can be reversed.
The replacement of the halogen atoms of the polyhalogenated polytertiobutyl intermediate compounds of formulas (II) or (III) obtained in the first stage, or of the polyhalogenated polyhydroxylated intermediate compounds obtained in the second stage, by ##STR11## is effected by the reaction of said intermediate compounds with a secondary amine of the formula ##STR12## wherein R and R.sub.1 have the meanings given above, at a temperature of 80-180.degree. C. without a solvent or in the presence of a solvent for at least one of the reactants which solvent, advantageously, is selected from alcohols, ethers and alkoxy alkanols and preferably, ethanol, ethyleneglycol, diethyleneglycol, dipropyleneglycol, the monomethyl-, monoethyl- or monobutyl-ethers of either monoethylene glycol or diethylene glycol.
Preferably an excess of at least 100% of the secondary amine to neutralize the hydracid formed is employed.
As the secondary amine there is used, preferably, N-methyl or N-ethyl alkylamines. The alkyl group has from 4-18 carbon atoms and is selected from, preferably, butyl, hexyl, octyl, decyl, dodecyl, tetradecyl, hexadecyl or octadecyl.
This reaction with the secondary amine can be followed by oxidation of the polyamine obtained to a corresponding polyamine oxide by means of an appropriate oxidizing agent which is, advantageously, H.sub.2 O.sub.2, preferably at a concentration of about 39 weight percent. Other oxidizing agents can also be used such as a peracid, including performic or peracetic acid. The reaction with the secondary amine can also be followed by a salification reaction using a mineral acid such as hydrochloric, hydrobromic, sulfuric and phosphoric acids, or an organic acid such as acetic, lactic, tartaric, oxalic or succinic acids.
The replacement of the halogen atoms of the intermediate compounds obtained in the first stage or in the second stage by a ##STR13## is carried out initially by the reaction with a secondary amine of the formula ##STR14## as indicated above, followed by a betainization reaction using an alkaline monochloroacetate, which is preferably sodium or potassium monochloroacetate.
The replacement of the halogen atoms of the intermediate compounds by a ##STR15## is carried out by initially reacting it with a secondary amine of the formula ##STR16## as indicated above, and then by quaternizing the polytertiobutoxy polyamine or polyhydroxylated polyamine with a quaternizing agent or a classic alkylating agent, for example, with a methyl- or ethyl-chloride, bromide, iodide, sulfate, methane sulfonate or paratoluene sulfonate.
The replacement of the halogen atoms X of the intermediate compounds by a ##STR17## is carried out by reacting said intermediate compound with a tertiary amine having the formula ##STR18## at a temperature of 80.degree.-180.degree. C. at atmospheric pressure or at a higher pressure in an autoclave, without a solvent or in the presence of a solvent for at least one of the reactants which solvent, advantageously, is selected from alcohols, ethers and alkoxy alkanols and preferably ethanol, ethyleneglycol, diethyleneglycol, dipropyleneglycol, the monomethyl- , monoethyl- or monobutylethers or either monoethyleneglycol or diethyleneglycol.
In the formula ##STR19## X.sup.- represents Cl.sup.- or Br.sup.- according as epichlorhydrin or epibromhydrin are used as epihalohydrin in the first stage for the preparation of the intermediate oligomer.
The replacement of the halogen atoms of the polyhalogenated intermediate compounds obtained in the first or second stages by ##STR20## wherein a represents 0 or 1, is carried out by reacting the intermediate compound with a thiol compound such as a mercaptan or an alkaline alkyl mercaptide, preferably, one of sodium or potassium, at a temperature of 80-120.degree. C. at atmospheric pressure or super-atmospheric pressure in an autoclave.
The reaction can be effected without a solvent or in the presence of a solvent for at least one of the reactants and preferably in the presence of a solvent indicated above for the reaction of the polyhalogenated intermediate compounds with a secondary amine.
The useful thiol compounds are, preferably butyl, hexyl, octyl, decyl, dodecyl, tetradecyl, hexadecyl or octadecyl mercaptans, or their alkaline salts.
The polythioether compounds thus obtained can be transformed into polysulfoxides by oxidation with an appropriate oxidizing agent, preferably, with H.sub.2 O.sub.2 at a concentration of about 39 weight percent (130 volumes), in the presence of a small amount of an acid, such as acetic acid, at a temperature of 30-50.degree. C., or with a peracid such as performic or peracetic acid.
The present invention also relates to the intermediate compounds of formulas (III) and (IV), below:
and
wherein T, X, n, m and n' have the meanings given above; --C.sub.2 H.sub.3 (CH.sub.2 OT)O-- represents the two isomeric units: ##STR21## and --C.sub.2 H.sub.3 (CH.sub.2 X)O-- represents the two isomeric units: ##STR22## these isomeric units being obtained as a result of the two possible ways in which the oxirane group opens.
The polyhydroxylated sequenced oligomers of formula (I) have good surface activity and their amphipatic characteristics (lipophilic and hydrophilic) can be modified at will be varying the --ZR group and the degrees of polymerization, m, n and n'. They are soluble or dispersible in water depending upon the value of the ratio, ##EQU1## and the meaning of the --ZR group.
For the same --ZR group, the compounds are all the more hydrophilic as the ratio ##EQU2## is large.
For the same value of ##EQU3## the hydrophilic character increases when the number of carbon atoms in R is reduced.
The oligomers include in their sequence, hydroxyl, amine or thioether groups which are reactive sites on which it is possible to effect such various chemical reactions as condensation, telomerization or alkylation reactions.
The oligomers can be used as surfactants, principally as weak foaming agents, wetting agents, detergents, emulsifying agents, peptizing agents, dispersants, softening agents, anticlogging agents, solubilization agents, penetrating agents, anti-redeposition agents, flotation agents, as antistatic finishes or as dyeing aids.
Their molecular weight is between about 500 and 5,000.
Their molecular weight and their weak aggressiveness make the compounds of formula (I) particularly interesting as additives in cosmetic compositions or as excipients in pharmaceutical compositions.
The present invention also relates to pharmaceutical compositions including as an excipient at least one polyhydroxylated sequenced oligomer surfactant of formula (I).
The present invention also relates to cosmetic compositions containing at least one compound of formula (I).

EXAMPLES OF PREPARING THE SEQUENCED OLIGOMER SURFACTANTS
Example IA -- Preparation of a Mixture of Polyhydroxylated Polyhalogenated Bisequenced Oligomers of the Formula:
to 14.8 g of tertiobutyl alcohol (0.2 mole), there are added over a 21/2 hour period, at a temperature of 70.degree. C., alternately in 3 fractions, 0.69 ml of BF.sub.3 etherate and 260 g (2 moles) of tertiobutyl glycidyl ether.
The temperature and agitation of the resulting mixture are maintained for 2 hours and 45 minutes. One checks by dosage that all the epoxide has been consumed. There are then added, alternately in 3 fractions at 70.degree. C., 0.9 ml of BF.sub.3 etherate and 92.5 g (1 mole) of epichlorohydrin. The addition lasts for 50 minutes.
After 11/2 hours of agitation at 70.degree. C., the reaction is practically complete. The hydroxyl index of the product obtained is 1.10 meg/g.
The product is washed three times, each time with 500 ml of boiling water. The washed product is then dehydrated by heating under reduced pressure.
After removing the most volatile materials (15.6%) by molecular distillation at a temperature of 180.degree. C., there is obtained a product having a molecular weight of 1,730, whose hydroxyl index is 0.94 meq/g and whose chlorine index is 2.59 meq/g.
This product is in the form of a pale yellow oil.
To the polyhalogenated polytertiobutyl derivative thus obtained, there are added 3 grams of sulfoacetic acid. The resulting mixture is then heated for 31/2 hours at 95.degree. C.
There are then slowly added 30 ml of water and the heating is continued for an additional 1 hour.
The reaction mixture is then diluted with water to a concentration of 10%. The catalyst is removed by passing the diluted reaction mixture over Amberlite MB I resin; the water is then removed by evaporation under reduced pressure.
There is thus obtained a deep brown polyhydroxylated polyhalogenated derivative whose hydroxyl index is 11.5 meq/g and whose chlorine index is 3.2 meq/g.
Example IB -- Preparation of a Mixture of Polyhydroxylated Polysulfoxide Nonionic Bisequenced Oiligomers of the Formula: ##STR23##
To 15 g (56 meq) of the polyhydroxylated polyhalogenated derivative prepared in Example IA, there are added 11.5 g (56 meq) of lauryl mercaptan and 20 ml of absolute ethanol. The resulting mixture is heated to 70.degree. C. There are then slowly added, with agitation and under a nitrogen atmosphere, 9 g of sodium methylate (6.2 meq/g) and the mixture is heated at reflux for 4 hours. The reaction mixture is then diluted with 70 ml of absolute ethanol and the sodium chloride formed in filtered.
After removal of the solvent under reduced pressure there is obtained an amber colored soft paste.
To 20 g (40 meq) of the mixture of thioethers thus prepared, there is initially added, with strong agitation 0.5 ml of acetic acid, and then at 35.degree. C. there are slowly added 3.44 ml (40 meq) of H.sub.2 O.sub.2 (130 volumes).
There is thus obtained a soft paste which is dispersible in water.
Example IC -- Preparation of a Mixture of Polyhydroxylated Cationic Bisequenced Oligomers of the Formula: ##STR24##
To 22 g of the mixture of polyhydroxylated polychlorinated derivatives prepared in Example IA, there are added 34 g (168 meq) of methyl laurylamine. The resulting mixture is heated with agitation and under a nitrogen atmosphere at 130.degree. C. for 6 hours.
The amount of transformation of the chloride is close to 100%. The reaction mixture is then diluted with 100 ml of isopropanol and the acid formed is neutralized with 7.8 g of sodium hydroxide (9.9 meq/g). The sodium chloride formed is filtered and the solvent is distilled under reduced pressure. The excess methyl laurylamine is then removed by molecular distillation at 140.degree. C., yielding a black brown pastey product.
After dissolution of this product in water, there is a slight opalescence which disappears by the addition thereto of a small amount of a mineral or organic acid.
Example IIA -- Preparation of a Mixture of Polytertiobutoxy Polyhalogenated Bisequenced Oligomers of the Formula:
wherein T represents tertiobutoxy.
To 14.8 g (200 meq) of tertiobutyl alcohol, there are added, with agitation, at 70.degree. C. and in three equal fractions, 0.61 ml of BF.sub.3 etherate and 234 g (1800 meq) of tertiobutyl glycidyl ether. The addition lasts 11/2 hours.
To the product thus obtained, having a hydroxyl index of 1.20 meq/g, there are added at 80.degree. C., 0.14 ml of BF.sub.3 etherate and 55.5 g (600 meq) of epichlorohydrin over a 30 minute period. The temperature and agitation of this mixture is maintained for 2 hours.
At that point the epoxide is practically all consumed. The product is washed three times, each time with 50 ml of boiling water. The washed product is then dehydrated by heating under reduced pressure. After removing the volatile materials by molecular distillation at 160.degree. C., there is obtained a pale yellow viscous liquid having a molecular weight of 1,060 and an organic chlorine content of 1.87 meq/g.
Example IIB -- Preparation of a Mixture of Polyhydroxylated Polysulfoxide Nonionic Bisequenced Oligomers of the Formula: ##STR25##
To 40 g (74.8 meq) of the polyhalogenated derivative prepared in Example IIA, there are added 15.6 g (74.8 meq) of lauryl mercaptan. To the resulting mixture, under a nitrogen atmosphere, at 65.degree. C., there are slowly added 12.1 g of sodium methylate (6.2 meq/g).
This mixture is then heated for 5 hours at about 80.degree. C. The rate of reaction, determined by dosage of the alkalinity and remaining mercaptans, is 91.5%. The resulting product is washed three times with 100 ml of boiling water. The water is then removed by heating under reduced pressure.
The tertiobutoxy groups are then hydrolyzed by heat at 95.degree. C. for 3 hours in the presence of 0.4 g of sulfoacetic acid. There are then slowly added 5 ml of water and the mixture is continued to be heated for 1 more hour. The resulting product is a brown viscous oil which is dispersible in water. Its hydroxyl index is 4.7 meq/g and its sulfur content in the form of thioether is 1.5 meq/g.
To 25 g of this derivative there is initially added 0.15 ml of acetic acid. Then, at 35.degree. C. there are slowly added 3.2 ml of H.sub.2 O.sub.2 (130 volumes), yielding an amber colored, very thick oil which is soluble in water.
Example IIC -- This Example Illustrates a Variation of the Process Described in Example IIB
To 100 g of the polyhalogenated derivative prepared in Example IIA, there is added 1 g of sulfoacetic acid. This mixture is heated at 90.degree. C. for 11/2 hours. Ther are then slowly added 5 ml of water and heating is continued for an additional 11/2 hours.
To 28.5 g (83 meq-Cl) of the immediately preceding derivative (Hydroxyl Index - 11.5 meq/g) there are added 17.5 g (83 meq) of lauryl mercaptan and 15 ml of absolute ethanol. This mixture is heated to 60.degree. C. and there are added thereto under a nitrogen atmosphere 13.4 g of sodium methylate (6.2 meq/g).
This mixture is maintained at reflux temperature for 5 hours. The reaction rate, determined by dosage of the alkalinity and remaining mercaptans is 93-95%.
There are then added to the reaction mixture 100 ml of absolute ethanol. The sodium chloride which was formed is filtered and then the alcohol is removed by heating under reduced pressure.
To 30 g (62 meq) of the resulting polythioether, there is initially added 0.15 ml of acetic acid. Then at 35.degree. C. under strong agitation there are slowly added 5.36 ml of H.sub.2 O.sub.2 (130 volumes).
The product thus obtained is a light chestnut colored soft paste which is soluble in water.
Example IID -- Preparation of a Mixture of Polyhydroxylated Cationic Bisequenced Oligomers of the Formula: ##STR26##
To 35 g (102 meq-Cl) of the polyhalogenated derivative prepared in Example IIA, there are added 24 g (214 meq) of methyl laurylamine. The resulting mixture is heated under a nitrogen atmosphere for 5 hours at 130.degree. C.
This reaction mixture is dissolved in 100 ml of isopropanol and there are added thereto 9.75 g of sodium hydroxide (9.9 meq/g).
The sodium chloride formed is separated by filtration and the excess methyl laurylamine is removed under reduced pressure. There is thus obtained a deep brown colored soft paste which produces cloudiness when admixed with water. However, on the addition of a mineral or organic acid thereto the solution becomes perfectly clear.
Example IIE -- Prepartion of a Mixture of Polyquaternary Polyhydroxylated Bisequenced Oligomer of the Formula: ##STR27##
To 16 g (29 meq of basicity) of the mixture of compounds obtained in Example IID, there are slowly added 3.6 g of dimethyl sulfate at a temperature of 50.degree. C. The reaction is exothermic and the temperature is maintained using a cooling bath. The addition lasts 1 hour.
There is thus obtained a light brown paste which is soluble in water. The rate of quaternization is 90%.
Example IIA -- Preparation of a Mixture of Polyhalogenated Trisequenced Oligomers of the Formula:
to 4.5 g (0.06 mole) of tertiobutyl alcohol there is initially added 0.2 ml of the acetic acid complex of boron trifluoride, and then at 80.degree. C., over a 1 hour period, there are added 46.5 g (0.36 mole) of tertiobutyl glycidyl ether. After 1 hour of agitation, there is initially added 0.2 ml of BF.sub.3 and then over a 11/2 hour period 33 g (0.36 mole) of epichlorohydrin. After complete consumption of the epichlorohydrin there are again added 0.4 ml of BF.sub.3 and 93.5 g (0.72 mole) of tertiobutyl glycidyl ether over a 2 hour period.
The resulting product is washed three times with 400 ml of boiling water. It is then dehydrated under reduced pressure.
After removal, by molecular distillation of the volatile materials, there is obtained a light yellow viscous product having a molecular weight of 1,000 and an organic chlorine index of 2.17 meq/g.
Example IIIB -- Preparation of a Mixture of Polyhydroxylated Polysulfoxide Nonionic Trisequenced Oligomers of the Formula: ##STR28##
To 90 g (195 meq-Cl) of the polyhalogenated derivative prepared in Example IIIA, there is added 0.8 g of sulfoacetic acid. This mixture is heated for 1 hour and 15 minutes at about 95.degree. C. There are then slowly added 5 ml of water and the heating is continued for an additional 3 hours.
The resulting product is then dissolved in 50 ml of water and 75 ml of isopropanol. The acidity is neutralized by stirring this mixture with 13 g of Amberlite MB 1 resin.
The resin is then filtered and the solvents are removed by heating under reduced pressure. The product thus obtained is a brown colored, sticky, very soft paste, which produces slight cloudiness when added to water.
To 22 g (73.3 meq) of the immediately preceding derivative, there are initially added 12 ml of ethanol, and then 15.4 g (73.3 meq) of lauryl mercaptan. The resulting mixture is heated to 65.degree. C. and there are slowly added thereto 11.8 g of sodium methylate (6.2 meq/g). The reaction mixture is maintained at reflux temperature of the alcohol for 51/2 hours. The rate of reaction is 93%.
After filtering the sodium chloride, there is obtained a product in the form of a brown colored, sticky, very soft paste which is dispersible in water.
To 24 g of the immediately preceding derivative (52.5 meq-sulfur in the form of thioether) there is initially added 0.12 ml of acetic acid, and then at 35.degree. C., with strong agitation, there are added 4.52 ml of H.sub.2 O.sub.2 (130 volumes) of about 39% w/w over a 25 minute period.
