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 such that when the composition is in contact with water, prior to application, the composition is at an alkaline pH; 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.
