The combination of an enzyme substrate and an enzyme capable of accelerating the modification of said substrate, provides a triggered release system which works especially well. The use of the enzyme-triggered release system can retain a rinse benefit agent during the wash stage and release it during the subsequent rinse stage.

Triggered release system

A particle comprising:&#x2014;(a) a spacer which is a polyethylene glycol (PEG) chain with molecular weight Mw (and therefore the required length) of the spacer extending from the particle from 3000 to 400,000; (b) a deposition aid; and (c) a benefit agent, wherein the spacer is attached directly to the particle and the deposition aid is attached to the end of the spacer.

Encapsulated benefit agents

The invention provides a benefit agent delivery particle comprising hydroxylpropyl cellulose. The benefit agent delivery particle may further comprise a non-polysaccharide polymer, preferably an aminoplast polymer. The benefit agent delivery particle may comprise a perfume. The invention also provides a process for the manufacture of the particles in which perfume oil is encapsulated using emulsion polymerization to form core-shell particles, (in the alternative the perfume may be adsorbed later) and, a further polymer layer is formed on the outer surface of the core shell-particles in the presence of the delivery aid.

Fabric treatment compositions comprising targeted benefit agents

A particle (preferably a core-shell encapsulate) comprising a benefit agent (preferably a perfume), said particle being bound to a non-cationic deposition aid which is substantive to polyester, wherein the non-cationic deposition aid is a polymer derivable from dicarboxylic acids and polyols. Preferably the polymer comprises units derived from (poly)ethylene glycol and terephthalate, most preferably selected from the group comprising PET/POET, PEG/POET, PET/PEG and phthalate/glycerol/ethylene glycol polymers. The invention also provides a method for producing improved benefit agent particles which comprises the step of covalently linking or co-polymerising a deposition aid which is substantive to polyester to a particle comprises the benefit agent. The particles find particular utility in laundry treatment compositions comprising (a) anionic and/or nonionic surfactant, or (b) cationic fabric conditioner and further comprising core-shell particles, wherein said particles have, incorporated in the shell a polyester-substantive deposition aid which is a phthalate containing polymer and incorporated in the core a perfume.

Fabric treatment composition comprising a core-shell particle bound to a phthalate-containing polymer

A laundry treatment composition comprising composition comprising: in which Rare independently of one another selected from H, a hydrolysable group, or a fibre reactive group in which when Ris a hydrolysable group the degree of substitution is 0 to 1, and wherein Ris a fibre reactive group the degree of substitution is from 0.05 to 1 and;

Laundry composition

The present invention is directed to a process for the preparation of polysaccharide grafted latex particles wherein the polysaccharide has &#x3b2;-1,4 linkages, wherein the process comprises core/shell emulsion polymerisation. Preferably, the process comprises a single step of preparing the latex particles by emulsion polymerisation of latex monomers with the simultaneous grafting of the polysaccharide.
