Abstract
Abstract Surface-active polysiloxanes are disclosed having the formula: ##STR1## in which x denotes an integer from 3 to 10 and A denotes a cationic, anionic, zwitterionic or nonionic hydrophilic unit which contains one or more of the same or different groups which are amine, amine oxide, ammonium, ammonioalkylcarboxylate, ammonioalkylsulphonate, amide, sulphonamide, ether, thioether, sulphoxide, hydroxyl, ester or acid groups. These polysiloxanes are particularly useful for use in cosmetic and pharmaceutical compositions, especially compositions for the hair.
