The present invention relates to a fragrance delivery system for use in laundry detergent compositions including rinse-added and dryer-added fabric conditioning compositions which provides a long lasting “freshness” or “clean” scent to fabric. The compositions described herein deliver highly fabric substantive linear acetal and/or ketal pro-fragrances to the fabric surface during laundering wherein the pro-fragrances release their fragrance raw materials over a period of up to two weeks. The present invention also relates a method for delivering a pleasurable scent to fabric which has a lasting freshness quality by contacting the fabric with a laundry detergent composition which comprises the fragrance-releasable pro-fragrances.
本发明涉及一种香氛传递系统,用于洗涤剂配方,包括添加到漂洗剂和烘干剂中的织物柔顺剂配方,为织物提供持久的“清新”或“清洁”香气。本文描述的配方在洗涤过程中将高度织物亲和性的线性缩醛和/或缩酮前香料传递到织物表面,其中前香料在长达两周的时间内释放其香料原料。本发明还涉及一种通过将织物与包含香氛可释放前香料的洗涤剂配方接触来为织物提供持久清新品质的愉悦香气的方法。
