Cosmetic compositions containing polyethylene glycol derivatives

Abstract

The invention relates to new polyethylene glycol derivatives.These compounds correspond to the general formula: ##STR1## in which R denotes an alkyl and/or alkoxymethyl and/or alkenyloxymethyl radical or a mixture of these radicals, n denotes an average number of units from 20 to 500 and preferably from 30 to 200, and x and y denote average numbers of units from 0 to 8, it being possible for (x+y) to vary from 1 to 8.They can be used in cosmetic or pharmaceutical compositions, in particular as thickeners.

Description

The present invention relates to products derived from polyethylene glycols and from alkylene oxides and/or from alkyl glycidyl ethers or alkenyl glycidyl ethers, their use and cosmetic and/or pharmaceutical compositions in which they are used.

Pharmaceutical and cosmetic compositions intended for use by topical application generally have a high viscosity, being presented in the form of oils, gels, creams or pastes.

This type of presentation is highly valued by the consumer; for the formulator, it most frequently satisfies a practical requirement, namely that of limiting the diffusion of the product, for locally applied compositions, to the treatment zone.

This requirement is particularly important for medicinal compositions, especially if it is desired to carry out local treatments, and it is equally real for the formulation of cosmetic compositions such as compositions intended for hair dyeing, which must not trickle onto the forehead or the neck, and of shampoos in concentrated form, which must not run into the user's eyes, and also for all the other topical applications for which it is desirable to limit the application of the composition to well-defined areas.

A certain number of thickening products have been used in the past for obtaining this result, in particular natural gums and synthetic anionic or cationic polymers.

The use of inorganic salts for increasing the viscosity of solutions of anionic surface-active agents has also been described.

However, it has been found that certain of these products are ineffective for thickening solutions based on surface-active agents, or compositions already containing polymers which flocculate on the addition of ionic thickeners.

Mixtures of polyethylene glycol monoesters and diesters have also been proposed as non-ionic thickeners for cosmetic compositions. However, the proportions of monoesters and diesters are difficult to control; in particular, these products are unstable, which results in a drop in the viscosity of the solutions as a function of time.

A new class of non-ionic compounds which can be used for increasing the viscosity of solutions of ionic or non-ionic surface-active agents has now been discovered, according to the present invention. By virtue of their non-ionic nature, they are more readily compatible with other ionic constituents. Furthermore, they have the great advantage of being chemically stable and of making it possible to obtain viscosities which are substantially constant as a function of time, at ambient temperature or at elevated temperatures.

The products of the invention are solubilized or dispersed in water at concentrations from about 20 to 60%, to give transparent or opaque gels. At lower concentrations, a separation into two phases is generally observed, one phase being gelled and the other completely fluid. However, the introduction of, say, 0.2 to 10% of products of this invention into solutions of surface-active agents makes it possible to obtain limpid or opalescent, homogeneous compositions of substantially increased viscosity.

In certain cases, the products of the invention can be used as foam synergistic agents.

The products can, in certain cases, reduce the aggressiveness of surface-active agents which can be present in certain cosmetic compositions such as soaps, shampoos, eye make-up removal lotions, and foam baths, for example.

The invention thus provides new derivatives of polyethylene glycols and of alkylene oxides and/or of alkyl glycidyl ethers or alkenyl glycidyl ethers, these products essentially being characterized in that they correspond to the general formula (I): ##STR2## in which R denotes an alkyl and/or alkoxymethyl and/or alkenyloxymethyl radical or a mixture of these radicals, n denotes an average number of units from 20 to 500 and preferably from 30 to 200, and x and y denote average numbers of units from 0 to 8 and preferably from 1 to 8, it being possible for the sum (x+y) to vary from 1 to 8, preferably from 2 to 8 and in particular from 2 to 6.

The alkyl radicals are preferably linear radicals having 8 to 18 carbon atoms; the alkoxymethyl or alkenyloxymethyl radicals preferably contain from 8 to 20 carbon atoms in the alkyl or alkenyl part.

The products according to the invention thus essentially consist of a polyoxyethyleneated sequence which is joined, at least at one end and preferably at both ends, to a very limited number of lipophilic units, the proportion by weight of the oxyethyleneated part desirably representing 70 to 95% of the product.

These products can be obtained, in particular, by adding one or more compounds of the general formula: ##STR3## in which R has the same meaning as given above, to mixtures of polyethylene glycols, in the presence of a basic catalyst.

Specific epoxides of the formula (II) which can be used include:

1,2-alkylene oxides such as 1,2-decene oxide, 1,2-dodecene oxide, 1,2-tetradecene oxide, 1,2-hexadecene oxide or 1,2-octadecene oxide; alkyl glycidyl ethers such as decyl glycidyl ether, dodecyl glycidyl ether, tetradecyl glycidyl ether, hexadecyl glycidyl ether, octadecyl glycidyl ether, eicosyl glycidyl ether, 2-methyldodecyl glycidyl ether, 2-methyltetradecyl glycidyl ether, 2-methylpentadecyl glycidyl ether, 2-hexyldecyl glycidyl ether or 2-octyldodecyl glycidyl ether, 2-ethylhexylglycidyl ether; oleyl glycidyl ether, undecylarylglycidyl ether or a mixture of these compounds.

The polyethylene glycols which can be used particularly according to the invention are polyethylene glycols with an average molecular weight of 1,000 to 20,000 and preferably 1,500 to 10,000.

The compounds corresponding to the formula II are preferably used in a molar ratio of 1 to 4:1 and more preferably 1.5 to 3:1 relative to the hydroxyl end groups of the polyethylene glycols.

The basic catalysts which are more particularly preferred in the process for the preparation of the products are alkali metal catalysts such as sodium, potassium, sodium methylate or ethylate or potassium methylate or ethylate, sodium hydroxide or potassium hydroxide.

These catalysts are suitably used in molar proportions of 10 to 300% and preferably 20 to 100%, relative to the polyethylene glycols.

The polyaddition reactions of the compounds of the formula (II) to the polyethylene glycols are generally carried out under an inert atmosphere and preferably under a nitrogen atmosphere, at a temperature of, say, 120.degree. to 180.degree. C.

After neutralization of the catalyst with hydrochloric acid, if appropriate, the addition products are usually in the form of white or slightly coloured waxes which are soluble or dispersible in water at a concentration of more than 20%, with gelling.

If these products are used at lower concentrations, a separation into two phases is observed, one phase being gelled and containing the products according to the invention, and the other virtually consisting of water. However, it is possible to prepare homogeneous compositions containing the products of the invention at concentrations of, say, 0.2 to 10% and preferably of 1 to 3% by weight, in the presence of one or more surface-active agents chosen from non-ionic, anionic, cationic, amphoteric or zwitterionic surface-active agents, or mixtures thereof, the proportion by weight of the products according to the invention varying from, say, 5 to 40%, relative to the surface-active agents. In this case, the products according to the invention make it possible to obtain limpid or slightly opalescent, aqueous solutions of substantially increased viscosity.

Because of their properties, the products according to the invention can be used as thickeners, in particular in cosmetics and in pharmacy, in the proportions mentioned.

The cosmetic and/or pharmaceutical compositions which form a further aspect of the present invention are essentially characterized in that they contain at least one product corresponding to the formula (I), together with a cosmetically and/or pharmaceutically active ingredient.

In general, the cosmetic and/or pharmaceutical compositions according to the invention are in the form of viscous liquids, gels, dispersions, creams or pastes.

In one embodiment, the cosmetic and/or pharmaceutical compositions according to the invention contain from 0.2 to 10% and preferably from 1 to 3% of the product according to the invention, in the presence of one or more surface-active agents which are non-ionic, anionic, cationic, amphoteric or zwitterionic derivatives, or mixtures thereof, the proportion by weight of the compounds according to the invention preferably being from 5 to 40%, relative to the surface-active agents.

The cosmetic compositions include, in particular, compositions intended for the care of the skin, nails and hair, which can also contain, for example, surface-active products, alkalising or acidifying agents, foam synergistic agents and foam stabilisers, other thickeners, opacifiers, sequestering agents, superfatting agents, antiseptics, preservatives, anionic, cationic, non-ionic or amphoteric polymers, pigments, perfumes, dyestuffs, agents for imparting pearlescence, solvents, sun filters, oxidising agents, reducing agents, electrolytes, oils, waxes, natural substances, protein derivatives, anti-seborrhoea agents, anti-dandruff agents and any other active substance which can have an action in the treatment, care or protection of the skin or hair, and any other adjuvant normally used in cosmetic compositions.

The compositions according to the invention can, in particular, be used as shampoos, foam baths, liquid soaps and lotions or creams to be applied before or after shampooing, before or after dyeing or bleaching or before or after permanent waving.

The compositions can also be used for dyeing or bleaching the hair, as creams or milks for the body or as make-up products. They can contain, in addition to the products of the present invention, other ingredients conventionally used in these types of composition.

The acids and the bases are generally used in amounts so as to adjust the pH of the compositions to 3 to 12 and preferably 3 to 10.

The pharmaceutical compositions also contain active substances intended for the treatment of the human or animal body and pharmaceutically acceptable excipients.

The following Examples further illustrate the present invention.

PREPARATION EXAMPLE (I)

5.8 g of sodium methylate containing 5.64 milliequivalents/g (33 milliequivalents) are added to 150 g (0.075 mol) of polyethylene glycol 2,000 (P.E.G. 2,000) molten at 90.degree. C., under a nitrogen atmosphere, and the mixture is then heated gradually to 150.degree. C., the methanol being removed at ordinary pressure and then under reduced pressure.

54 g (0.225 mol) of 1,2-epoxyhexadecane are then introduced dropwise, at 150.degree.-155.degree. C., in the course of about 40 minutes.

The heating and the stirring are maintained for 1 hour after the addition has ended.

The degree of completion of the reaction, assessed by determining the remaining epoxide groups, is 97.5%.

The basicity introduced is neutralised by adding 33 ml of normal hydrochloric acid.

After drying by heating under reduced pressure, a light yellow wax melting at 29.degree. C. is obtained.

The compound obtained corresponds to the following formula: ##STR4##

The other compounds of the invention, shown in Table 1 which follows, are prepared in the same way; this table indicates the nature of the P.E.G., the nature of the epoxide compound of the formula II together with the amounts used, the molar ratios of the compounds of the formula II to the P.E.G., and the amounts of sodium methylate, expressed in milliequivalents per gram.
