| abstract |
The present invention relates to fragrance precursors. In particular, the invention relates to the use of various classes of compounds that can act as fragrance precursors, for example in cosmetic products such as deodorants and antiperspirants, and in laundry products such as detergents and fabric softeners. These compounds are normally odorless or nearly odorless, but with the skin conduit as for example in skin care compositions or in personal care compositions, they produce fragrances. The compounds also produce fragrances when used in the presence of lipases, for example as those used in detergents (laundry), thus providing a prolongation of the perfuming effect of fabrics. The compounds under consideration are the compounds of formula I: (See Formula). Substituents are defined in the specification. |
