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.
摘要:
The invention relates to the use of aminoalcohol derivatives containing a urea functional group corresponding to the following formula: in which: R1 represents a linear or branched, saturated or unsaturated alkyl radical having from 8 to 22 carbon atoms; R2 represents a hydrogen atom or a linear or branched, saturated alkyl radical having from 1 to 6 carbon atoms; R3 represents a linear or branched, monohydroxylated or polyhydroxylated, saturated alkyl group having from 1 to 10 carbon atoms, in and for the preparation of cosmetic or dermatological compositions. These compounds are used in particular as moisturizing agents in care products for the skin or as conditioning agents in hair products.

摘要:
A cosmetic or dermatological composition containing, as an active substance, at least one natural or recombinant spider silk protein, or an analog of such a protein. The composition may be in the form of hair products, skincare products, make-up products or antisun products.
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:
The invention concerns the use of flavylium type compounds, non-substituted in position 3, and substituted by at least a hydroxyl or alcoxy radical, in particular Apigenidin, in pure form or in the form of plant extracts containing them, as coloring agent in or for making compositions for dyeing keratinous fibers, particularly human keratinous fibers such as hair. The invention also concerns the dyeing compositions containing them, particularly cosmetic compositions for direct hair dyeing, and the corresponding dyeing method. The hair dyes resulting from the use of these coloring agents are particularly stable to light and washing.
摘要:
Lysine derivatives, salts of the derivatives, their optical isomers of D or L configuration, or their mixtures, the derivatives containing an Ne-alkoxy or Ne-alkenoxycarbonyl group and having the formula: in which: R represents a linear or branched C13-C24 alkyl radical or alkenyl radicals, are used in cosmetic, pharmaceutical, hygiene or food compositions, particularly compact compositions.
摘要:
