A solid composition for releasing active silicone ingredients contains a cationic polymer, an active silicone ingredient and optionally a thickener and a carrier. The cationic polymer is preferably a homopolymer or a copolymer. The cationic polymer has higher water solubility at neutral pH than at a basic pH of 9-11. Granular encapsulated compositions can be prepared by using the solid silicone-releasing composition as a component in a laundry detergent powder, tablet or bar. This is particularly of interest for the delivery of silicone ingredients in the rinse cycle of a laundry operation.

Delivery system for releasing silicone ingredients

This invention relates to aqueous emulsions comprising a polyorganosiloxane and a wax, and to methods of production of such emulsions. The emulsions are of the type oil-in-water. An organopolysiloxane is polymerized in admixture with a molten wax, thereby forming a blend of the wax with an organopolysiloxane of increased molecular weight, and the said blend of polymer and molten wax is emulsified in water in the presence of a surfactant. The emulsions are useful in personal care applications such as on hair, skin, mucous membrane or teeth. The emulsions are also useful in applications such as paints, water based coatings, textile fiber treatment, leather lubrication, fabric softening, fabric care in laundry applications, homecare, release agents and oil drag reduction.

Organopolysiloxane emulsions and their production

A foam control agent comprises (A) an organopolysiloxane material having at least one silicon-bonded substituent of the formula X&mdash;Ph, wherein X denotes a divalent aliphatic hydrocarbon group and Ph denotes an optionally substituted aromatic group, (B) an organosilicon resin and (C) a hydrophobic filler. The organosilicon resin (B) preferably consists of siloxane units of the formula R&prime; SiO wherein R&prime; denotes a hydroxyl, hydrocarbon or hydrocarbonoxy group, particularly trialkylsiloxy units and SiO4/2 units, wherein a has a value of from 0.5 to 2.4. The foam control agent may be provided as an emulsion or as a particulate material. It is especially useful as a detergent foam control agent.
