Abstract: A process for preparing silicate shell microcapsules comprises adding a water reactive silicon compound to an oil in water emulsion, thereby condensing and polymerizing the water reactive silicon compound to form silicate shell microcapsules having a core comprising the oil phase of the said emulsion. The water reactive silicon compound comprises a tetraalkoxysilane and an alkoxysilane having an amino or quaternary ammonium substituted alkyl group.

Abstract: A fabric, fibre, hair or skin conditioning additive for use in a liquid cleaning product is encapsulated within a shell comprising a silicon-containing polymer network.

Abstract: An emulsion for controlled fragrance release comprises a disperse phase which is a blend of a fragrance composition and a waxy hydrophobic material having a melting point in the range 10-200° C. dispersed in a continuous phase comprising an aqueous solution of concentration at least 0.1 molar of a salt capable of ionic disassociation in water.

Abstract: A domestic care product comprising a fragrance particle wherein the particle comprises a fragrance composition and at least one silicone polymer having a melting point of at least 10° C., provided that at least 20% of the silicone atoms in the silicone polymer have a substituent of 16 carbon atoms or more. The fragrance may be employed in relatively small proportions and yet deliver fragrance to a domestic care product over a prolonged period of time by use these silicone polymers.

Abstract: This invention relates to a particulate foam control agent comprising from 1 to 30 parts by weight of a silicone antifoam, from 70 to 99 parts by weight of a zeolite carrier for the antifoam, from 1 to 60% by weight of the silicone antifoam of a surface active agent which has been deposited on the zeolite carrier not later than the silicone antifoam and from 1 to 40 parts by weight of a polycarboxylate-type binder or encapsulant, whereby the polycarboxylate-type binder has a pH of 3 or less when dissolved in water. The invention also relates to a detergent composition comprising the particulate foam control agent and a method for the preparation of the foam control agent.
