Cosmetic or pharmaceutical compositions comprising modified polyorganosiloxanes

摘要

Linear organopolysiloxane-polyoxyalkylene copolymers of the formula (I)
are described, in which
R 1 and R 2 , independently of one another, are a straight-chain or branched, saturated alkyl group having 6 to 22 carbon atoms or are a straight-chain or branched, mono- or polyunsaturated alkenyl group having 6 to 22 carbon atoms,
R 3 , R 4 , R 5 , R 6 , R 7 and R 8 , independently of one another, are a straight-chain or branched, saturated alkyl group having 1 to 30 carbon atoms, a straight-chain or branched, mono- or polyunsaturated alkenyl group having 2 to 30 carbon atoms or a phenyl radical,
m and p are numbers from 4 to 50 and
n is a number from 3 to 90. The linear organopolysiloxane-polyoxyalkylene copolymers of the formula (I) can be used in an advantageous way in cosmetic or pharmaceutical compositions.
Moreover, they are suitable particularly for the cleansing and care of the hair and the skin, as emulsifier in emulsions, preferably in O/W or W/O emulsions, and as conditioners.
