Patent ID: 8012544

Claim:
A method of making an aqueous silicone emulsion containing a crosslinked silicone elastomer comprising mixing; (i) 1-95 parts by weight of a linear hydroxy terminated polydiorganosiloxane, (ii) 5-60 parts by weight of a silanol containing silicone MQ resin, providing there is at least 40 parts of component (ii) per 100 parts of component (i), and (iii) 0.1-30 parts by weight of an organofunctional polysiloxane, to form a water-insoluble homogeneous silicone oil phase; admixing at least one emulsifier and water to the silicone oil phase to obtain an aqueous silicone base emulsion; adding a sufficient amount of an acidic or basic compound to the aqueous silicone base emulsion in order to adjust the pH of the aqueous silicone base emulsion to an acidic or basic pH necessary to facilitate condensation and crosslinking of the linear hydroxy terminated polydiorganosiloxane and the silanol containing silicone MQ resin in forming a crosslinked silicone elastomer; and neutralizing the aqueous silicone emulsion containing the crosslinked silicone elastomer.
