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.
Claims17
A fabric, fibre, hair or skin conditioning additive for use in a liquid cleaning product, wherein a fabric, skin, hair or fibre conditioning agent is encapsulated within a shell comprising a silicon-containing polymer network, and wherein the shell is a polymerization product of a tetraalkoxysilane and a quaternary aminosilane having at least one silicon-bonded alkoxy radical.
A process for preparing an encapsulated fibre, skin, hair or fabric conditioning additive, the process comprising adding a liquid composition comprising a water reactive silicon compound (composition A) to an aqueous emulsion of a fibre, skin, hair or fabric conditioning agent (composition B), thereby condensing and polymerising the composition A at its interface with the emulsified droplets of the composition B to form microcapsules, wherein the composition B has a core of the fibre, skin, hair or fabric conditioning additive surrounded by a shell comprising a silicon-based polymerized network, wherein the composition B comprises a cationic aqueous emulsion containing 10 to 50% by weight of an amino-functional polyorganosiloxane.
An encapsulated polyorganosiloxane in a liquid laundry detergent composition, wherein the encapsulated polyorganosiloxane is encapsulated within a shell comprising a polymerization product of a tetraalkoxysilane and a quaternary aminosilane having at least one silicon-bonded alkoxy radical.
A process for preparing an encapsulated fibre, skin, hair or fabric conditioning additive, the process comprising adding a liquid composition comprising a water reactive silicon compound (composition A) to an aqueous emulsion of a fibre, skin, hair or fabric conditioning agent (composition B), thereby condensing and polymerising the composition A at its interface with the emulsified droplets of the composition B to form microcapsules, wherein the composition B has a core of the fibre, skin, hair or fabric conditioning agent surrounded by a shell comprising a silicon-based polymerized network, wherein the shell is a polymerization product of a tetraalkoxysilane and a quaternary aminosilane having at least one silicon-bonded alkoxy radical.
