摘要 |
<p>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 comprising 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.</p> |
