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.
一种颗粒(最好是核-壳封装颗粒),包括一种益处剂(最好是香料),该颗粒与一种对聚酯有亲和力的非阳离子沉淀助剂结合,其中该非阳离子沉淀助剂是由二羧酸和多元醇衍生的聚合物。最好的情况是该聚合物包括由(聚)乙二醇和对苯二甲酸酯衍生的单元,最好是PET / POET,PEG / POET,PET / PEG和邻苯二甲酸/甘油/乙二醇聚合物。该发明还提供了一种制造改进的益处剂颗粒的方法,其中包括将对聚酯有亲和力的沉淀助剂与包含益处剂的颗粒共价链接或共聚合。该颗粒在包括(a)阴离子和/或非离子表面活性剂的洗涤剂组合物或(b)阳离子织物柔顺剂并进一步包括核-壳颗粒的洗涤剂组合物中具有特殊的实用性,其中所述颗粒在壳中包含对聚酯有亲和力的沉淀助剂,该沉淀助剂是含邻苯二甲酸的聚合物,并在核中包含香料。
