摘要:
The present invention relates to perfume or fine fragrance compositions inter alia perfumes, colognes, eau de toilettes, and after shave lotions, comprising pro-accord compounds which release their fragrance raw material components on a delayed basis therefore providing sustained fragrance levels to the user. Typically the pro-accords are comprised of orthoesters, ketals, acetals, orthocarbonates which release two or more fragrance raw materials upon hydrolysis. The present invention also relates to an article of manufacture comprising a first pro-accord containing reservoir and a second fragrance raw material reservoir and a means for admixing and applying the perfume material.

摘要:
Detergent compositions containing certain acetals or ketals which hydrolyze upon exposure of surfaces washed in solution of said compositions to a reduction in pH, thereby releasing a fragrance which is characteristic of one or more of the hydrolysis products. The acetals and ketals themselves also form part of the invention; they have a molecular weight of at least about 350; a ClogP of about 4, and a half-life of less than 60 minutes when measured at pH=0 by the pro-fragrant hydrolysis test.

This invention is a fabric delivery system for liquid laundry detergent compositions which comprises a &bgr;-ketoester selected from a Markush group of &bgr;-ketoesters. Laundry compositions also contain surfactants and carriers.
摘要:
The present invention relates to a fragrance delivery system for use in laundry detergent compositions which provides a long lasting "freshness" or "clean" scent to fabric. The compositions described herein deliver highly fabric substantive .beta.-ketoester 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 to 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 .beta.-ketoester pro-fragrances.

Rinse added fabric softening compositions containing pro-fragrant acetals or ketals which hydrolyze upon exposure of surfaces rinsed in solution of said compositions to a reduction in pH, thereby releasing a fragrance which is characteristic of one or more of the hydrolysis products.

Laundry and cleaning compositions comprising a nonionic or anionic ester of an allylic alcohol perfume having the formula: ##STR1## especially geranyl and neryl esters.
摘要:
Esters of perfume alcohols having at least one free carboxylate group are provided. The esters have the general formula: ##STR1## wherein R is selected from the group consisting of substituted or unsubstituted C.sub.1 -C.sub.30 straight, branched or cyclic alkyl, alkenyl, alkynyl, alkylaryl or aryl group; R' is a perfume alcohol with a boiling point at 760 mm Hg of less than about 300.degree. C.; and m and n are independently an integer of 1 or greater. The esters are employed as perfume components in laundry and cleaning compositions such as fabric softening compositions.
