Abstract
The invention relates to a silicon/water emulsion comprising, in an aqueous medium: PA0 1/ an organopolysiloxane containing a diester functional group containing, per molecule, at least one unit of formula: EQU ZR.sub.a SiO.sub.(3-a)/2 where Z has the formula: ##STR1## where the symbols R' are C.sub.1 -C.sub.12 monovalent saturated hydrocarbon, C.sub.2 -C.sub.12 alkoxyalkyl or C.sub.6 -C.sub.12 aryl, alkylaryl or arylalkyl radicals, the symbol X is H or CH.sub.3, the symbol W is a covalent bond or a C.sub.1 -C.sub.4 alkylene radical, the symbols R are C.sub.1 -C.sub.20 alkyl, vinyl, phenyl, 3,3,3-trifluoropropyl or hydroxyl radicals, only one of the radicals R per silicon atom denoting hydroxyl, a is equal to 0, 1 or 2; PA0 2/ an emulsifier chosen from anionic, cationic, amphoteric or nonionic surfactants. Application: to the treatment of textile fibers, to the coating of flexible substrates and to the cosmetic or dermatological treatment of hair or of the skin.
