Emulsions are prepared by heating and polymerizing a mixture containing (i) a non-crosslinked silicone polyether; (ii) optionally, a cosurfactant which can be a monohydroxy alcohol, diol, triol, or glycol ether; (iii) an =Si-H containing polysiloxane; (iv) a mono-alkenyl polyether; (v) an alpha,omega-diene, alpha,omega-diyne, or alpha,omega-ene-yne; (vi) optionally, a silicone oil such as (a) a low molecular weight linear or cyclic volatile methyl siloxane, or (b) a low molecular weight linear or cyclic volatile or non-volatile alkyl or aryl siloxane; (vii) a platinum catalyst; and (viii) water.
