Abstract
This invention provides deodorant and deodorant-antiperspirant cosmetic stick and roll-on products with an organic matrix having a dispersed phase of discrete particles of an encapsulated bicarbonate salt such as sodium bicarbonate, and discrete particles of an encapsulated fragrance compound such as musk ketone. The particle surfaces are coated with a polymer such as maltodextrin starch. When this type of cosmetic product is applied to underarm surfaces, the deodorizing activity is signaled by the release of a fragrance aroma.
