Abstract
A cosmetic composition for the care of skin and hair is provided which contains from 0.1% to 10% of a silicone-containing phospholipid composition having the general formula: ##STR1## wherein: A is selected from H, M or R--Y--; PA1 A.sub.1 is selected from H, OH, OM or R--Y--O--; PA1 M is a cation; PA1 Y is alkylene or substantially alkylene; PA1 x is 0 or an integer from 1-5; and PA1 R is a quaternized organosilicone amidoamine reactant moiety of the formula: ##STR2## wherein: R.sub.10 is the silicone backbone chain to which at least one pyrrolidone containing amidoamine functional group is attached; PA1 R.sub.6 is hydrogen or alkyl, hydroxyalkyl or alkenyl of up to 6 carbon atoms each, cycloalkyl of up to 6 carbon atoms, or polyoxyalkylene of up to 10 carbon atoms within the oxyalkylene unit; PA1 R.sub.7 and R.sub.8 are selected from alkyl, hydroxyalkyl, carboxyalkyl of up to 6 carbon atoms in each alkyl moiety and polyoxyalkylene of up to 10 carbon atoms; PA1 F is linear or branched alkylene of 1-12 carbon atoms; PA1 X.sup.- is an anion; PA1 n is 0 or 2; PA1 n.sup.1 is 0 or 1; PA1 n.sup.2 is 0 or 1; PA1 n.sup.3 is an integer from 2 to 12. PA1 B is --NR.sub.11 sulfur or oxygen, w…
