摘要:
The use of alkyl N-(hydroxyalkyl)carbamates in a cosmetic or pharmaceutical composition provided in the form of an aqueous lotion, a gel, an emulsion, a cream, a foam or a paste.
摘要:
The invention relates to new hydrocarbon compounds containing a fluorinated chain of formula I ##STR1## and to their process of preparation. The invention also relates to the use of these new compounds as thickening agents, in particular for non-aqueous media, such as cosmetic compositions, and to the cosmetic compositions containing them.
摘要:
A fluorohydrocarbon compound of formula RF—C2H4—O—CO—RH, in which RF is a perfluorinated alkyl group and RH is an alkyl group, in and/or for the preparation of a stable emulsion containing at least one fatty phase and one aqueous phase. The invention also relates to the use of the same compound as a stabilizing agent for an emulsion containing at least one fatty phase and one aqueous phase. Another subject of the invention is the use of such a compound as an essential component of the fatty phase of an emulsion and emulsions containing such a fatty phase. Another subject of the invention is a composition comprising such an emulsion.
摘要:
The ceramides according to the invention are compounds corresponding to the formula: ##STR1## in which: R.sub.1 is a C.sub.11 to C.sub.21 alkyl or alkenyl radical; R.sub.2 is a linear or branched C.sub.1 to C.sub.29 hydroxyalkyl radical or a C.sub.7 to C.sub.29 hydroxyaralkyl radical, these compounds being in the form of a racemic mixture of the erythro and threo diastereoisomers for the aminodiol part ##STR2## in erythro:threo ratios of from 85:15 to 20:80. Application to cosmetic and dermopharmaceutical compositions.
