ABSTRACT:
Organopolysiloxane-polyoxyalkylene block copolymers having a limited number of dimethylsiloxane units, at least one 6 to 16 carbon alkyl radical and at least one polyoxyalkylene radical are good emulsifiers for preparing water-in-mineral oil emulsions if the polyoxyalkylene radicals do not account for more than 1/3 of the molecular weight of the block copolymer. The block copolymers are readily dispersible or dissolvable in mineral oil to which a personal care component can be added. Personal care emulsion compositions can then be prepared by emulsifying an aqueous phase into the mineral oil phase.
