Description
The invention relates to new polyanionic oligomers, the process for their preparation and their use in cosmetic compositions.
Anionic polymers have already been proposed for cosmetic uses, in particular in lacquers or in hair care compositions.
These polymers are homopolymers or copolymers of moderate or high molecular weight, which give the style hold and have a hardening effect on the hair.
Current fashion advocates a more supple style without stiffness.
The new oligomers satisfy this requirement. They provide the style with hold, with suppleness and without a significant and overall hardening effect on the hair.
Moreover, the new anionic oligomers according to the invention have a better compatibility with the cationic polymers with which they are combined in the preferred compositions of the invention.
The cosmetic hair care compositions containing the oligomers according to the invention furthermore provide wet hair with ease of comb-out and dried hair with a more attractive general appearance.
The compounds of the invention can be represented by the following general formula (I): ##STR3## in which T denotes the radical ##STR4## the radical ##STR5## or a mixture of 50-99.5% of one of these radicals and 0.5 to 50% of the OH radical, the percentages being expressed as molar percentages;
u=zero or 1;
p=1 or 2;
M denotes a hydrogen, sodium or potassium atom, an ammonium radical or a mono-, di- or tri-(alkyl or hydroxyalkyl)-ammonium group, in which the alkyl radical contains from 1 to 4 carbon atoms;
n denotes an integer or decimal number from 5 to 30;
z denotes an integer from 1 to 6 and preferably from 1 to 3; and
R denotes a straight-chain or branched, saturated or unsaturated aliphatic radical or an alicyclic, aryl, alkylaryl or aralkyl radical of valency z, which can contain from 1 to 12 oxygen atoms.
The compounds of the formula (I) can contain minor proportions of intermolecular or intramolecular branches originating from the use of bis-epoxides.
The radicals R are derived from compounds containing an alcohol or phenol group (or groups), of the formula (II):
They act as initiators and can have a very wide variety of structures.
Amongst the alcohols and phenols of the formula (II) which can be used within the spirit of the invention, the following may be mentioned in particular as examples:
linear and branched alkanols having from 1 to 18 carbon atoms;
alkenols having 8 to 18 carbon atoms, for example undecylenyl alcohol and oleyl alcohol;
ethylene glycol alkyl ethers and diethylene glycol alkyl ethers and derivatives thereof, in particular the compounds known under the name "cellosolves" (ethylene glycol monoalkyl ethers and derivatives thereof) and under the name "carbitols" (diethylene glycol monoalkyl ethers and derivatives thereof);
ether-alcohols of the formula (IIa) ##STR6## in which v=0 or 1 and R.sub.1 and R.sub.2 are aliphatic radicals having from 1 to 18 carbon atoms, the sum of the carbon atoms in R.sub.1 and R.sub.2 preferably being less than or equal to 24;
alkanols, alkenols and ether-alcohols of the formula (IIa), polyoxyethyleneated with 1 to 10 mols of ethylene oxide per mol of alochol;
alkylene-1,2-glycols, alkylene-1,3-glycols and alkylene-.alpha.,.omega.-glycols having from 2 to 18 carbon atoms;
polyoxyethylene glycols and polyoxypropylene glycols having a molecular weight of less than 2,000;
polyols such as glycerol, sorbitol, pentaerythritol and glucose, optionally partially alkylated or acylated;
phenols and their unsubstituted or substituted derivatives, optionally polyoxyethyleneated with 1 to 10 mols of ethylene oxide per mol of phenol; amongst the phenol derivatives, examples which may be mentioned are bisphenols and alkylphenols, which are optionally oxyethyleneated; and
mixtures of these compounds.
The products of the formula (I) according to the invention are obtained by the polyaddition of n mols of epihalogenohydrin, such as epichlorohydrin or epibromohydrin, onto one mol of alcohol or phenol of the formula (II), in the presence of a catalyst chosen from amongst Lewis acids such as boron trifluoride, tin tetrachloride and antimony pentachloride, according to the following reaction scheme, giving rise to the formation of compounds of the formula (III) ##STR7## in the formula (III), X denotes Cl or Br; n is an integer or decimal number from 5 to 30, representing an average statistical value and indicating the number of epihalogenohydrin molecules used per molecule of compound (II);
z denotes an integer from 1 to 6 and represents the number of OH equivalents in the molecule (II); and
n/z represents an average statistical value and indicates the number of halogen-containing units formed in the polyether chain from each OH group.
As a result, the number of halogen-containing units formed in the polyether chain from each OH group of the alcohol R(OH).sub.z can be less than, equal to or greater than the quotient n/z, but the total number of these halogen-containing units formed is equal to n.
As another result, the process for the preparation of the compounds of the formula (I) leads to a mixture of compounds.
The epihalogenohydrin polyaddition reaction is carried out at a temperature of between 30.degree. and 100.degree. C., without a solvent or in the presence of a solvent which is inert with respect to the reactants, for example in the presence of a hydrocarbon such as hexane or heptane, or in the presence of a chlorinated solvent such as methylene chloride or dichloroethane.
At the same time as the epihalogenodydrin, it is possible to add minor proportions of a bis-epoxide such as, for example, diglycidyl ether or the bisglycidyl ether of bisphenol A. The bis-epoxide will form intermolecular or intramolecular branches.
The proportions of bis-epoxide added per mol of compounds (III) are 0.5 to 5%.
The catalyst is used in proportions varying from 0,1 to 3% by weight, relative to the reaction mixture.
The polyhalogen compounds of the formula (III) are then converted to polythiocarboxylic compounds by reaction with the sodium or potassium salts of thioglycolic acid or .alpha.-mercaptopropionic or .beta.-mercaptopropionic acid, or with the corresponding methyl or ethyl ester, and saponification of the esters obtained.
These halogen substitution reactions are carried out in the presence of NaOH or KOH if the salts of thioglycolic acid or .alpha.-mercaptopropionic or .beta.-mercaptopropionic acid are used, and in the presence of sodium methylate or ethylate or potassium methylate or ethylate if the esters are used, in solvents which are generally alcohols such as ethanol, propanol or isopropanol, glycols such as ethylene glycol or propylene glycol, or glycol ethers such as cellosolves, diethylene glycol or dipropylene glycol, optionally in the presence of water. The reaction temperature is generally between 80.degree. and 120.degree. C.
If the group T represents a mixture of radicals ##STR8## and OH, the halogen is first substituted by the radical ##STR9## by reaction of the intermediates of the formula (III) with the salt or the ester of thioglycolic acid of .alpha.-mercaptopropionic or .beta.-mercaptopropionic acid, as indicated above, and the halogen of the still unconverted intermediates of the formula (III) is then substituted by OH by reaction with NaOH or KOH at a temperature of 100.degree.-120.degree. C., or with sodium acetate or potassium acetate at a temperature of 160.degree.-180.degree. C., in one of the solvents indicated above which has a sufficiently high boiling point.
The products thus obtained are optionally saponified and then generally acidified and washed with water, without a solvent or in the presence of a solvent such as isopropanol, n-butanol, t-butanol or butoxyethanol.
The polycarboxylic acids are then partially or totally neutralised with NaOH, KOH, NH.sub.4 OH or an aliphatic amine, and optionally subjected to steam distillation in order to deodorise them.
The aliphatic amines which can be used to neutralise the acid groups are chosen from amongst alkylamines such as mono-, di- or tri-ethylamine or mono-, di- or tri-(iso)propylamine, or alkanolamines such as mono-, di- or tri-ethanolamine, mono-, di- or tri-isopropanolamine, 2-amino-2-methylpropane-1,3-diol or 2-amino-2-methylpropan-1-ol.
The deodorising treatment can be improved by the addition of a small amount of 0.05 to 2% of a compound capable of reacting rapidly with sulphydryl compounds. Ethylene oxide and glycidol may be mentioned amongst the compounds preferred for this purpose.
The products of the formula (I) obtained according to the invention are kept in aqueous solution or isolated by evaporation to dryness, and optionally taken up in non-solvents.
These compounds can be oxidised with hydrogen peroxide at a temperature of between 20.degree. and 50.degree. C. to give the compounds of the formula (I) in which u denotes 1.
The invention also relates to the products obtained by the processes described above.
The invention also relates to the compositions containing a mixture of compounds of the formula (I). A composition of this type advantageously contains from 0.2 to 50% of these products. The compositions in an aqueous of aqueous-alcoholic medium can be presented in the form of solutions, gels, creams, pastes or dispersions and can be packaged in the form of aerosols to give foams or sprays.
Examples which may be mentioned of alcohols which can be used in the aqueous-alcoholic compositions are alkanols such as ethanol, isopropanol and propanol, alkoxyethanols such as cellosolves or carbitols, and glycols such as ethylene glycol, propylene glycol, butylene glycol, diethylene glycol or dipropylene glycol. The proportion of alcohol constituent in the compositions is generally from 5 to 50% by weight.
The compositions are suitable for use in the care and treatment of keratin fibres and also in a variety of industries, in particular in the textile industry of for water treatment.
When used in the care and treatment of keratin fibres, especially hair, these compositions can be, in particular, shampoos, products for facilitating styling or setting, rinse-off or leave-on lotions, products for perming or straightening, products for colouring or bleaching, and so on.
In these compositions, the following can be combined with the products of the invention: non-ionic, anionic, cationic, amphoteric and zwitterionic surfaceactive agents or mixtures thereof, anionic, cationic, amphoteric and non-ionic polymers, thickeners, agents for imparting pearlesence, foam synergistic agents or foam stabilisers, dyestuffs, colouring products, sequestering agents, preservatives, perfumes, inorganic or organic salts, reducing agents, oxidising agents, opacifiers, peptising agents, oils, waxes, natural substances, protein derivatives, anti-seborrhoea agents, anti-dandruff agents, pH modifiers and also any other substance which can have an action in the treatment or care of the hair.
The preferred compositions of the invention contain the oligomers of the formula (I) in combination with cationic polymers.
The invention also relates to a process for the treatment of keratin fibres, and especially hair, which consists in applying, to the keratin fibres, a sufficient amount of a composition such as defined above.
The invention also relates to a process for the treatment of textiles with a composition such as defined above.
The invention also relates to a process for the treatment of water with a composition containing a mixture of compounds (I).
The invention will be illustrated with the aid of the non-limiting examples below.

34.2 g of bisphenol A (0.15 mol) are dispersed in 60 ml of dichloroethane at 50.degree. C. 0.85 ml of BF.sub.3 /ether complex is then added, after which 208 g of epichlorohydrin (2.25 mols) are added dropwise in the course of 1 hour. Stirring is continued for 1 hour at 50.degree.-60.degree. C. and the solvent is evaporated off. Functional group analysis is used to check that all the epoxide groups have reacted.

143 g of thioglycolic acid containing 10.5 milliequivalents/g (that is to say 1,500 milliequivalents of carboxyl groups) are neutralised with 309 g of 40% strength NaOH solution under a nitrogen atmosphere.
161.5 g of the product obtained by the process described above (1,500 milliequivalents of chlorine), solubilised in 80 g of methylcellosolve (ethylene glycol methyl ether), are then introduced at 80.degree. C. in the course of 45 minutes. The reaction mixture is then heated for 2 hours at 100.degree. C. The degree of completion of the reaction, assessed by determining the remaining sulphydryl groups, is of the order of 96%.
The mixture is diluted with 300 g of water and then acidified by the addlition of 265 ml of 6N hydrochloric acid (1,590 milliequivalents).
The organic phase is decanted and washed twice with 250 g of water at 70.degree. C. About 50 g of butoxyethanol or isopropanol can be added during the first decantation in order to fluidise the organic phase.
150 g of water and 130 g of 40% strength NaOH solution are then added. The solvent is driven off under reduced pressure and the residue is taken up in water so as to give, after total removal of the butoxyethanol, a solution containing about 41% of active ingredients. This solution is in the form of a clear, light yellow liquid with a pH of the order of 9. The basicity index is 2.32 milliequivalents/g (determination of the carboxylate group).

C.
The reaction mixture is heated for 3 hours at 100.degree. C. and then progressively up to 180.degree. C., the water being removed by evaporation. The mixture is thus heated at this temperature for 3 hours.
The reaction mixture is taken up in 50 g of water and 30 g of 40% strength NaOH solution for 1 hour at 70.degree. C.
The resulting mixture is then evaporated to dryness and the residue is taken up in isopropanol to remove the last traces of solvents. The precipitate is filtered off, drained and dried.
The product thus obtained is in the form of a sandy-coloured powder which is prefectly soluble in water. The basicity index is 2.3 milliequivalents/g.

300 g of 40% strength NaOH solution are then introduced in the course of 10 minutes. The reaction is exothermic and the temperature rises rapidly from 25.degree. C. to 75.degree. C.
The mixture is heated for 2 hours under reflux, the ethanol is then distilled and the residue is taken up in water so as to be in a homogeneous medium.
The resulting mixture is heated again for 2 hours at 100.degree. C. It is acidified by the addition of 125 ml of concentrated hydrochloric acid.
The compounds of the formula (I) in the acid form separate out from the aqueous phase. 80 g of n-butanol are added.
