The present invention relates to a personal care composition suitable for application to hair, skin or nails, containing: a) a polyorganosiloxane emulsion containing: i) a polyorganosiloxane dispersed as particles in the emulsion, the polyorganosiloxane having a size average particle less than 150 nanometers containing a dysfunctional repeating unit "D": where n is greater than 1 and R1 and R2 are independently C1-C7 alkyl, phenyl, aminoalkyl, carboxyalkyl, haloalkyl, acrylate, acryloxy, acrylamide , mercaptoalkyl or vinyl; Said siloxane may be terminated with hydroxy group, alkoxy groups or trimethylsiloxy groups. ii) a surfactant system comprising anionic, cationic or nonionic surfactants or mixtures thereof, to disperse the polyorganosiloxane in the emulsion; b) from 0.01% to 10% of a silicone polyoxyalkylene linear block copolymer surfactant, having the formula : M´Db D1c M´ where M´ is a monofunctional unit R2 R´Si O½ D is a difunctional unit R2 SiO2 / 2 D´ is a difunctional unit RR´SiO2 / 2 R is independently H, C1-C6 alkyl or aryl; R 'is independently an oxyalkylene, H or CH3 containing medium; where when R´ is an oxyalkylene-containing medium, it has the formula: -R "(OCn CH2n) and --R" ´whereR "in a divalent radical to connect the oxyalkylene portion of the R´ medium to the siloxane start; ... |
