摘要:
Primary amine salts of derivatives having formula: R'O--CO--NH--CH(R)--COOH wherein R is --CH.sub.2 OH or --CHOHO--CH.sub.3, and R' is an optionally insaturated alkyl group having at least 10 carbon atoms, as well as the least partial salification products of the derivatives of formula (I) with primary amines, and whose salification degree is sufficient to obtain, in aqueous solution, a pH higher than 6 and lower than 7.5; and cosmetic compositions, in the form of emulsions, containing them. These primary amine salts which have hydrating properties for the skin, have also the property of stabilizing emulsions.
摘要:
A cosmetic or dermatological composition containing a mixture of at least one type-III ceramide in the form of a single stereoisomer and of at least one type-V ceramide. This mixture is in particular a mixture having a melting point which is much lower than that of the type-III ceramide. This composition is intended in particular for moisturizing dry skins.
摘要:
The present invention relates to a stable oil-in-water emulsions comprising an oily phase dispersed in an aqueous phase with an emulsifying system. More precisely, the emulsifying system contains a first ester chosen from the fatty acid esters of glucose and the fatty acid esters of alkylglucose and at least one second fatty acid ester of sucrose. The emulsion according to the invention may be used in the cosmetic field and in the field of dermatology in order to obtain a skin cream.
摘要:
UV-photoprotective, topically applicable cosmetic/dermatological compositions contain: (a) at least one silicon-containing s-triazine substituted with two aminobenzoate or aminobenzamide groups of specific formula (I), and (b) at least one non-silicon-containing lipophilic 1,3,5-triazine compound UV-screening agent, such compositions having improved photoprotective effectiveness in the UV-B range and the 1,3,5-triazine compound(s) being improvedly soluble therein.
摘要:
The invention relates to a composition comprising, in a cosmetically acceptable carrier, a system for screening out UV radiation, characterized in that it contains:(a) at least metal oxide-based mineral pigments, and(b) at least one hydroxyalkylurea of formula (I) below: in which R1, R2, R3 and R4 each independently represent a hydrogen atom, a C1-C4 alkyl group or a C2-C6 hydroxy-alkyl group that may contain from 1 to 5 hydroxyl groups, at least one of the radicals R1-R4 representing a hydroxyalkyl group, and also a salt, solvate or isomer thereof, said composition containing no kojic dipalmitate. The invention also relates to the use of a hydroxyalkylurea of formula (I) in a composition comprising, in a cosmetically acceptable carrier, at least metal oxide-based mineral pigments, for reducing, or even eliminating, the whitening effect on the keratin material after application.
摘要:
Stable UV-photoprotective, phase inverted oil-in-water emulsions, well suited for the photoprotection of the skin, lips and/or hair, the average size of the globules which constitute the oily phase thereof ranging from 100 nm to 1,000 nm, contain inorganic metal oxide nanopigments and at least one organic UV-screening agent, and which also contain at least one organic 4,4-diarylbutadiene UV-A-screening agent.
摘要:
Cosmetic, notably anti-sun/sunscreen compositions having reduced whitening effect on keratin materials, e.g., human skin, contain at least one system for screening out UV radiation, and also contain: (a) at least one metal oxide mineral pigment, and (b) at least one hydroxyalkylurea compound of formula (I): in which R1, R2, R3 and R4 each independently represent a hydrogen atom, a C1-C4 alkyl radical or a C2-C6 hydroxyalkyl radical containing from 1 to 5 hydroxyl groups, at least one of the radicals R1—R4 representing a hydroxyalkyl group, or salt, solvate or isomer thereof, formulated into (c) a topically applicable, cosmetically acceptable carrier therefor.

Cosmetic, notably anti-sun/sunscreen compositions having improved comfort after application onto keratin materials, e.g., human skin, contain at least one system for screening out UV radiation, and also contain: (a) at least one insoluble organic UV-screening agent, and (b) at least one hydroxyalkylurea compound of formula (I): in which R1, R2, R3 and R4 each independently represent a hydrogen atom, a C1-C4 alkyl radical or a C2-C6 hydroxyalkyl radical containing from 1 to 5 hydroxyl groups, at least one of the radicals R1-R4 representing a hydroxyalkyl group, or salt, solvate or isomer thereof, formulated into (c) a topically applicable, cosmetically acceptable carrier therefor.
摘要:
Topcially applicable photoprotective compositions having improved sun protection factor, cosmetic properties and/or stability contain: (a) at least one 1,3,5-triazine UV-screening agent, (b) at least one mixture including: (i) at least one arylalkyl benzoate compound, and (ii) at least one oil containing in its structure at least one amide unit.
摘要:
The invention relates to the use of at least one amphiphilic copolymer comprising at least one hydrophilic block and at least one hydrophobic block to stabilize dispersions of insoluble organic compounds comprising at least one group that absorbs UV radiation, which is in the form of particles with a mean size of between 10 nm and 5 &mgr;m, and also to dispersions stabilized with these amphiphilic copolymers and to cosmetic compositions for topical application, in particular antisun compositions, containing them.
