A skin conditioning composition comprising: (A) from about 5% to about 30% glycerin; (B) from about 0.5% to about 10% of a volatile silicone or mixtures thereof selected from the group consisting of methylsiloxane fluids having the average unit formula [Figure] wherein a has an average of from 2 to 3, inclusive; (C) from about 0.05% to about 1% of a polydiorganosiloxane-polyalkylene copolymer containing at least one polydiorganosiloxane segment and at least one polyoxyalkylene segment, said polydiorganosiloxane segment consisting essentially of [Figure] siloxane units wherein b has a value of from 0 to 3, inclusive, there being an average value of approximately 2 R radicals per silicon for all siloxane units in the copolymer, and R denotes a radical selected from the group consisting of methyl, ethyl, vinyl, phenyl and a divalent radical bonding said polyoxyalkylene segment to the polydiorganosiloxane segment, at least 95% of all R radicals selected from the group consisting of carbon, hydrogen, nitrogen, and oxygen being methyl; and said polyoxyalkylene segment having an average molecular weight of at least 1000 and consisting of from 0 to 50 mol percent polyoxypropylene units and from 50 to 100 mol percent polyoxyethylene units, at least one terminal portion of said polyoxyalkylene segment being bonded to said polydiorganosiloxane segment, any terminal portion of said polyoxyalkylene segment not bonded to said polydiorganosiloxane segment being satisfied by a terminating radical; the weight ratio of polydiorganosiloxane segments to polyoxyalkylene segments in said copolymer having a value of from 2 to 8; (D) from about 0.25% to about 5% of a surfactant or mixture of surfactants having an HLB of from about 8 to about 14; and (E) the remainder water.
