Abstract:
Topically applicable UVA photoprotective cosmetic/dermatological compositions comprise an effective photoprotecting amount of at least one UVA screening agent substituted by at least one optionally neutralized sulfo functional group, and an effective UVA photoprotecting-enhancing amount of at least one otherwise non-UVA photoprotecting iron chelating agent, thereby imparting a synergistic protection factor (PF) effect thereto, in a cosmetically/dermatologically acceptable topical vehicle, carrier or diluent therefor.
Abstract:
A cosmetic composition consisting essentially of (i) a fatty phase, (ii) at least one fatty acid ester of a C.sub.5 -C.sub.7 carbohydrate, and (iii) at least one polyol.
Abstract:
Use in association, as oil thickners, in a cosmetic composition comprising an oily phase, of at least one first copolymer including patterns derived from at least one lipophilic monomer and patters derived from at least one hydrophilic monomer, comprising at least one carboxylic acid or sulphonic grouping, and of at least one second copolymer including patterns derived from at least one lipophilic monomer and patterns derived from at least one hydrophilic monomer comprising at least one amine, amide, alcohol or ether grouping. Said first and second copolymers have a molecular weight of not less than approximately 100 000. The association enables thickened composition to be obtained, the texture, look and feel of which correspond to a cosmetic use.
Abstract:
Composition for the treatment of acne containing a dispersion of vesicles of ionic or non-ionic amphiphilic lipids, the vesicles containing in the lipid phase at least one salicylic acid derivative of formula (I): ##STR1## in which R represents a linear or branched C.sub.11 -C.sub.17 alkyl radical; R'.sub.1, R'.sub.2, R'.sub.3, which are identical or different, represent a C.sub.1 -C.sub.18 alkyl or hydroxyalkyl radical, it being possible for one of the radicals R'.sub.1, R'.sub.2 or R'.sub.3 to be a benzyl radical. The derivative of formula (I) serves both as charged lipid and as anti-acne active ingredient. The derivatives of formula (I) in which, when R represents a C.sub.13 -C.sub.17 alkyl radical, R'.sub.1, R'.sub.2, R'.sub.3, when they are identical, do not represent a hydroxyethyl radical.
