A composition for use as an anti-foam in laundry detergent wherein the anti-foam active ingredient is released slowly throughout the wash and rinse cycle.

Anti-foam composition

A sequential catalysis of the ring opening polymerization of cyclic organosiloxanes using a base catalyst that can be neutralized by a subsequent redistribution and condensation catalyst such as a Lewis acid catalyst, preferably a phosphonitrilic compound, permits the rapid synthesis of functionalized and poly-functionalized silicone copolymers such as alkenyl hydride copolymers, a new composition of matter. The instant claims are drawn to branched siloxanes having both Si--H and Si-alkenyl groups.

Process for preparing hydrogen siloxane copolymers
