SILICONE EMULSION AND USES THEREOF

Aqueous silicone emulsion compositions which cure utilising titanium-based reaction products as catalysts, and a process to prepare the same and their uses, are provided. The composition comprises (a) a titanium-based reaction product; (b) one or more silicon containing compounds having at least 2 or at least 3 hydroxyl and/or hydrolysable groups per molecule; (c) one or more surfactants; and (d) water. The titanium-based reaction product (a) is obtained or obtainable from a process comprising the steps of: (i) mixing a first ingredient, an alkoxy titanium compound having from 2 to 4 alkoxy groups with a second ingredient, a linear or branched polydiorganosiloxane having at least two terminal silanol groups per molecule and a viscosity of from 30 to 300,000 mPa·s at 25° C.; (ii) enabling the first and second ingredients to react together by stirring under vacuum to form a reaction product; and (iii) collecting the reaction product of step (ii).
