Abstract:
A cosmetic composition comprisingat least one inorganic-organic hybrid prepolymer having an Siâ€”Oâ€”S network and made by hydrolytic precondensation of at least one organofunctional silane of formula (I): RSiX3â€ƒâ€ƒ(I), wherein R represents a crosslinkable organic group selected from the group consisting of alkyl, alkenyl, alkynyl, aryl, arylalkyl, alkylaryl, arylalkenyl, alkenylaryl, arylalkynyl, and alkynylaryl crosslinkable groups, and wherein said alkyl, alkenyl, alkynyl, aryl, arylalkyl, alkylaryl, arylalkenyl, alkenylaryl, arylalkynyl and alkynylaryl crosslinkable groups may optionally be interrupted by at least one O, S, or N atom, OR wherein R denotes an organic group that is not crosslinkable by itself but contains a crosslinkable substituent and said crosslinkable substituent is selected from the group consisting of halogen, amino, amido, aldehyde, keto, alkylcarbonyl, carboxy, mercapto, cyano, hydroxyl, alkoxy, methacryloxy, epoxy, and vinyl groups; and wherein X denotes a hydrolyzable and condensable group selected from the group consisting of hydrogen, alkoxy, aryloxy, acyloxy, alkylcarbonyl, alkoxycarbonyl, halogen and substituted or unsubstituted amino groups; and and at least one cosmetic ingredient selected from the group consisting of water, organic solvents, non-setting nonionic polymers, non-setting anionic polymers, non-setting natural polymers, thickeners, perfumes, opacifers, anionic surfactants, cationic surfactants, amphoteric surfactants, nonionic surfactants, humectants, colorants, dyes, light-stabilizers, anti-oxidants, preservatives, propellants, and silicone polymers.
