DELIVERY SYSTEMS FOR ACIDIC ACTIVES

摘要

A delivery system comprises a mixture of at least one compound having formula (I), wherein R<1> and R<2> are independently hydrogen or a hydrocarbyl moiety such that R<1>COR<2> is an aldehyde or ketone, and Q is a substituted or unsubstituted C1 to C12 alkyl, alkenyl, aryl or alkaryl moiety, providing that from 1 to 3 contiguous carbon atoms of Q are part of the ring structure of formula (I); and an acceptable vehicle. Where the delivery system is a perfume composition, the acceptable vehicle conveniently comprises at least one fragance material. Many other vehicles are also possible, depending principally on the nature of the delivery system. The invention also provides a method for delivery hydroxy acids and aldehydes or ketones to a substrate comprising applying to the substrate a compound of formula (I), and a perfume composition comprising at least one compound of formula (I).
