ABSTRACT:
Described is a fragrancing composition having fragrancing components that are not activated until, e.g., application to the skin of a human. The composition is alkaline or (if anhydrous) capable of producing an alkaline pH when in contact with water, prior to application, and includes (1) a vehicle for application of the composition, and (2) at least one potential fragrance that is at least one compound having little or no odor in the alkaline composition but which, e.g., is hydrolyzed in a lower pH environment to produce compounds having a relatively strong aroma. Upon application of the alkaline composition to the skin surface, the strong buffering capacity of the skin (the surface of which has a normal pH of 5.5-7.0) neutralizes alkalinity of the composition (lowers pH) so as to restore normal skin surface pH; the potential fragrance is then hydrolyzed at the lower pH to release the compound having relatively strong aroma. The potential fragrance can be incorporated as a component of a transparent (clear) deodorant stick composition for application to human axillary regions, the fragrance being released after application to the body.
