This invention relates to alkylmethylsiloxanes mixtures which are useful for softening and moisturizing skin. The mixtures comprise one or more alkylmethylsiloxane solvents of the structure [MeRSiO]a[Me2SiO]b or R min Me2SiO(MeRSiO)w(Me2SiO)xSiR min Me2 and one or more alkylmethylsiloxane waxes of the structrure R min Me2SiO(Me2SiO)y(MeRSiO)zSiMe2R min , wherein each R is independently a hydrocarbon of 6 to 30 carbon atoms, R min is methyl or R, a is 1-6, b is 0-5, w is 0-5 and x is 0-5, provided a + b is 3-6 and w is not 0 if R min is methyl.
