Surface active composition

Claim 1

A process for preparing a transparent aqueous micro-emulsion or transparent gel in which a surface active composition and an organo-silicon compound are mixed together and the resulting mixture introduced into an aqueous medium wherein the surface active composition comprises by weight: p1 a. 45 to 90% of at least one n-alkyl monoether of a polyethylene glycol, containing 4 to 9 --CH 2 CH 2 O-- units, the n-alkyl radicals containing 5 to 15 carbon atoms, b. 5 to 35% of a sodium dialkylsulphosuccinate, the linear or branched alkyl radicals containing 6 to 12 carbon atoms, c. 2 to 17% of at least one acid selected from the group consisting of oleic, linoleic, linolenic and ricinoleic acid, and d. 1.5 to 12% of at least one amine selected from the group consisting of triethanolamine and N-hydroxyethylmorpholine, and wherein the organosilicon compound is a monomer of the formula R 4 Si or R 3 SiO a SiR 3 or an organopolysiloxane polymer having 0.8 to 2.6 organic groups per silicon atom and formed of units selected from the group consisting of R 3 SiO 0 .5, R 2 SiO, RSiO 1 .5, SiO 2 and O 3-b R b/2 SiQ a SiR b O 3-b/2 in which R represents a monovalent organic group containing 1 to 20 carbon atoms, Q represents a divalent hydrocarbon radical having 1 to 12 carbon atoms, a is 0 or 1 and b is 0, 1 or 2, the organosilicon compound forming 0.05 to 15% by weight of the emulsion or gel and the mixture of the surface active composition and the organo-silicon compound forming at most 60% of the weight of the emulsion or gel.
