Description

The invention relates to a novel surfactant composition which can be used in the preparation of cosmetic and pharmaceutical formulations having a topical use.

The use of emulsions in cosmetics or in dermopharmaceuticals is very common in the design of hygiene or care products. The formulations of this type make it possible to achieve a harmonious combination, in a homogeneous form easy to employ, of an oily phase and an aqueous phase containing ingredients of antagonistic nature, sometimes lipophilic, sometimes hydrophilic.

The emulsifying agents used under these circumstances can be of different natures. If its chemical structure concerned does not carry a charge, this compound is described as nonionic surface-active agent; if a negative charge, counterbalanced by a cation, is attached to it, it is an anionic surface-active agent; if charges of different natures coexist on the carbon-based sequence of the same chemical structure, it is an amphoteric surface-active agent; and, finally, if the chemical structure comprises a group having a positive charge counterbalanced by an anion, it is a cationic surface-active agent.

The favored ranges of applications of cationic surface-active agents are hair products and cosmetic formulations having a high presence of inorganic and/or organic fillers, such as anti-sun products. Creams, in particular those having a depilatory use, and lotions can also comprise such cationic surface-active agents.

Cationic surface-active agents of quaternary ammonium type are the most widely used in the cosmetics industry [Martin M. Reiger, “Harry's Cosmeticology”, 8th Edition, (2000), Vol. I I-II, p. 201, Chemical Publishing]. They are in particular quaternary ammonium structures, such as trimethylstearylammonium chloride or behenyltrimonium methanesulfonate [Michael and Irene Ash, “Handbook of Lubricants”, (2012), (2nd Edition), 999, Synapse Information Resources], sold for example by Croda under the name Incroquat Behenyl TMS [E. W. Flick, “Cosmetic and Toiletry Formulations”, (1997), Vol. 6 (2nd Edition), 126, 210, Noyes Publications], or of trialkylbenzylammonium type, such as the benzyldimethylstearylammonium chlorides appearing in the Stepan range under the Ammonyx trade names [Ernest W. Flick, “Cosmetics additives, An industrial guide” (1991), 725, Noyes Publications].

Access to cationic surface-active agents is based very largely today on a quaternization reaction of an alkyldimethylamine with a quaternization agent capable of transferring a carbon-based group, generally a methyl radical, which reaction can be illustrated by the following scheme:

R′ representing, for example, an alkyl radical comprising from 8 to 22 carbon atoms, R″ representing a methyl radical or an ethyl radical and Y representing a halide, methyl sulfate or ethyl sulfate anion.

Another approach is based on the involvement of tertiary amines of low molecular weights and of alkyl halides intended to bestow a fatty chain on the final structure and to confer surfactant properties on it. The abovementioned scheme also makes it possible to illustrate it when R′ represents, for example, a methyl radical or a benzyl radical, R″ represents an alkyl radical comprising from 8 to 22 carbon atoms and Y represents a halide, methyl sulfate or tosylate anion.

In point of fact, the reactants employed according to these two approaches are of synthetic or petrochemical origin and are dangerous for the health and for the environment. This is thus particularly the case for halogenated derivatives and dimethyl and diethyl sulfates. With regard to the fatty dimethylamines, they generally originate from the conversion of fatty acids [Harold A. Wittcoff et al., “Industrial Organic Chemicals” (2004), 419, Wiley-Interscience], which also involves reactants, such as ammonia or hydrogen, which are problematic to use and which often require the presence of catalysts based on heavy metals, such as cobalt or nickel.

It has thus appeared necessary to be able to have available cationic surfactant derivatives which can be obtained from reactants not exhibiting pronounced risks for the health of man and for the environment and which can be employed under mild conditions easy to control on the industrial scale.

Glycine betaine, which is naturally present in certain fruits, such as orange or lemon, cereals, such as oats, barley or wheat, or in beet, has recently appeared as an advantageous alternative to conventional routes for achieving cationic surfactant structures [F. Nsimba Zakanda et al., “Thin Solid Films”, (2011), 520, 344-350]. This is because this compound structurally carries a positive charge and makes it possible to transfer, under suitable conditions, this cationic nature to the structure to which it is chemically bonded. Glycine betaine is extracted from beet molasses, of which it represents approximately 27% by weight.

The international application published under the number WO 2005/121294 discloses novel compositions describing mixtures of alkyl hexosides or xylosides and of fatty esters or amides of glycine betaine which can be used in bactericidal, fungicidal or preserving compositions.

The international application published under the number WO 2005/121252 discloses the use of glycine betaine derivatives in cold bituminous emulsions and mentions the preparation of glycine betaine esters or amides.

The international application published under the number WO 2005/121291 discloses the use of glycine betaine derivatives in cosmetic emulsions.

The present invention relates to novel compositions which combine glycine betaine fatty esters and esters of glycine betaine and of alkyl polyglucosides, which include in particular structures of alkyl polyglucosides type carrying a cationic group introduced by virtue of a controlled grafting of glycine betaine.

EXAMPLE 1: PREPARATION OF A COMPOSITION (C1)

19.9 mmol of methanesulfonic acid are added, in a reactor, to 13.33 mmol of glycine betaine, 1.33 mmol of compound of formula (III), in which m is equal to 1.25 and R2 represents a tetradecyl radical, and 11.95 mmol of tetradecanol. The mixture thus obtained is placed under reduced pressure (5 to 10 mbar) and is heated at 70° C. for approximately 18 hours. The reaction is monitored, on the one hand, by 1H NMR analysis in the solvent CDCl3/MeOD (1:1 v/v) and, on the other hand, by thin layer chromatography by elution in the AcOEt/AcOH/H2O (7:2:1 v/v/v) mixture. The conversion of the compounds of formula (III) to give compounds of formula (I) determined by proton NMR is 39%. The composition (C1) is obtained, which composition (C1) comprises, as molar percentages, the following compounds:

Mesylate of glycine betaine [Compound of formula (V)]: 19%

Methanesulfonic acid [Compound of formula (IX)]: 34%

Tetradecyl alcohol [Compound of formula (II)]: 21%

Mesylate of the tetradecyl ester of glycine betaine [Compound of formula (IV)]: 24%

Compounds of formula (I) in which R2 represents a tetradecyl radical: 0.5%

Compounds of formula (III) in which R2 represents a tetradecyl radical: 1.5%

EXAMPLE 2: PREPARATION OF AN EMULSION ADVANTAGEOUS IN THE COSMETIC FIELD STARTING FROM A COMPOSITION ACCORDING TO THE INVENTION

The aqueous phase is an aliquot portion of a solution of demineralized water, the pH of which is adjusted beforehand to 5.5 by virtue of controlled additions of acetic acid and sodium acetate. The fatty phase (20 g of a mixture of triglycerides of caprylic/capric type, sold by Dubois under the name Dub MCT™ 5545) and the aqueous phase (171 g) are brought beforehand separately to 80° C. The emulsifying composition (C1) prepared in example 1 is dissolved with stirring in the fatty phase and then 1 g of “Caesalpinia spinosa gum”, sold by SEPPIC under the name Solagum Tara, is introduced into the fatty phase immediately before the mixing of the two phases using an apparatus of rotor-stator type of the Silverson brand. The emulsion thus formed is subsequently brought back to ambient temperature under gentle stirring (150 rev/min) with an impeller of anchor type. A preservative can optionally be added during this latter phase. This type of emulsion remains stable in an oven at 45° C. for one month.

EXAMPLE 3: PREPARATION OF AN EMULSION ADVANTAGEOUS IN THE COSMETIC FIELD STARTING FROM A COMPOSITION ACCORDING TO THE INVENTION

An emulsion like that of the preceding example 2 was prepared but without incorporating “Caesalpinia spinosa gum”. The emulsion thus formed remains stable in an oven at 45° C. for one month.
