Abstract

The invention relates to fragrance precursors. In particular, the invention relates to the use of several classes of compounds which can act as fragrance precursors, e.g. in consumer, e.g. cosmetic products, such as deodorants and antiperspirants. These compounds are normally odourless or nearly so, but upon contacting theskin as, for example, in skin care compositions or in personal care compositions, produce fragrances by liberating an odoriferous alcohol.
