ABSTRACT:
Perfumes containing normal perfuming components, such as essential oils, esters, ethers, aldehydes, alcohols, hydrocarbons, ketones and lactones, have the fragrances thereof desirably altered, and often significantly strenghtened, by incorporation with them, as another perfuming component, of a N-lower alkyl neoalkanamide, such as ethyl neodecanamide, or a mixture of such neoalkanamides. It has been found that the neoalkanamides are of desirable fragrances, are stable, even in alkaline media, such as built detergent compositions, maintaining their fragrance notes in the perfumes and in perfumed products during comparatively lengthy storage periods, and are significantly substantive to surfaces contacted by them, even when such contact is made in relatively dilute media, such as aqueous wash water, as when ther neoalkanamide (preferably methyl- or ethyl neodecanamide) is a component of a perfume that has been employed to perfume a detergent composition. Furthermore, experimentation has indicated that the described neoalkanamides act to strengthen the fragrances of other perfuming components of the perfumes.
