Abstract
This invention provides cosmetic deodorant stick, roll-on and cream formulations. An invention deodorant product comprises an organic matrix having a dispersed solids phase which includes discrete crystallites of bicarbonate salt ingredient and particulate boron oxide desiccant ingredient. When an invention deodorant product is applied to a skin surface, the boron oxide reacts with moisture, and converts to boric acid which neutralizes any content of a strong basic irritant such as alkali metal carbonate which is present as an impurity in an alkali metal bicarbonate salt.
