    • 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.
    • 描述了一种具有芳香组分的芳香组合物,其直到例如施用于人的皮肤为止才被活化。 该组合物是碱性的或(如果是无水的)能够在施用之前与水接触时产生碱性pH,并且包括(1)施用该组合物的载体,和(2)至少一种潜在的香料, 至少一种在碱性组合物中具有很少或没有气味的化合物,例如在较低pH环境中水解,生成具有较强香味的化合物。 当将碱性组合物施用于皮肤表面时,皮肤的强缓冲能力(其表面的正常pH为5.5-7.0)中和组合物的碱度(降低pH),以恢复正常的皮肤表面pH; 然后将潜在的香料在较低pH下水解以释放具有较强香味的化合物。 潜在香料可以作为透明(透明)除臭棒组合物的组分掺入到人类腋窝区域中,该香料在施用于身体后被释放。
