Abstract A surface active composition comprises by weight: 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 oleic, linoleic, linolenic and ricinoleic acid and D. 1.5 to 12% of at least one amine selected from triethanolamine and N-hydroxyethylmorpholine. The composition may be used as an emulsifier with diorganopolysiloxanes to form transparent micro-emulsions or transparent gels or to introduce silane cross-linking agents into catalyzed aqueous polysiloxane emulsions to cross-link the emulsion.
