摘要:
An O-acyl product derived from glucose which may be obtained by partial or total esterification of glucose and of vitamin F, comprising a mixture of esters, for example, monoesters, of glucose and of at least one acid chosen from linoleic acid, oleic acid, palmitic acid and stearic acid, compositions, for example, cosmetic and pharmaceutical compositions, comprising this novel derivative, and their use for improving the condition of head hair and/or other hairs, and, for example, for reducing and/or impeding the loss of head hair and/or other hairs, and/or for inducing and/or stimulating hair growth, as well as a process for preparing O-acyl derivatives mainly in position 6 of glucose, comprising preparing a mixed anhydride by reacting a carboxylic acid with a trimethylacetyl halide, followed by reacting said mixed anhydride formed with glucose.

摘要:
Process for the preparation of O-acylated glucose derivatives, in particular O-acylated predominantly in the 6 position, by reaction of a carboxylic acid with an alkyl haloformate, so as to form a mixed anhydride, and then reaction of the mixed anhydride with glucose.
摘要:
Novel pyrrolidinyl-substituted para-phenylenediamine derivatives comprising a cationic radical, the dye compositions comprising them and the process for dyeing keratin fibers using these compositions, making it possible to obtain a chromatic, powerful, unselective and fast coloration of keratin fibers.
摘要:
The invention relates to novel histidine derivatives corresponding to the general formula (I) below: in which: R denotes a linear or branched, saturated or unsaturated alkyl radical containing from 6 to 22 carbon atoms, n is an integer ranging from 1 to 16, Q+ represents H+ or an organic or inorganic cation, and the addition salts with an acid. The invention also relates to a process for preparing the compounds of formula (I), as well as to the use of these compounds in cosmetics and pharmacy.

摘要:
A cosmetic composition comprising, in a cosmetically acceptable medium, at least one compound of formula (I) in which R1, and R′1 are chosen from alkyl radicals and R2, R′2, R3, R′3, R4, R′4, R5, and R′5 are chosen from a hydrogen atom, a halogenated radical, a hydroxyl radical, an alkyl, alkyloxy, acyl, or acyloxy radical having 1 to 6 carbon atoms. The use of compounds of formula (I) for coating substrate particles, the resulting powder substance, and its use in a cosmetic composition.
摘要:
The use of carbohydrate derivatives in or for making a topical composition for promoting skin exfoliation is disclosed. The use of said composition of controlling intrinsic and extrinsic skin ageing, as well as a non-therapeutic skin treatment method for skin exfoliation, are also disclosed.
摘要:
The invention concerns a composition, in particular a cosmetic composition, comprising at least a powder substance and a branched amide used as dispersion agent. The invention also concerns novel branched amides of formula (I′).
摘要:
A composition containing at least one retinoid and at least one histidine derivative. The histidine derivative improves the stability of the retinoid in the composition. The composition may be used to treat skin and/or hair.
