It also relates to processes for their preparation and their uses in therapy and in cosmetic; such as an antiperspirant and a deodorant agent.
- Antiperspirant and deodorant compositions are popular personal care products used to prevent or eliminate perspiration and body odor caused by perspiration. Most of antiperspirant compositions commonly used include at least one antiperspirant active ingredient that minimize or prevent the secretion of perspiration by blocking or plugging ducts of sweat-secreting glands. Further, most of the deodorant compositions include at least one deodorant active agent that minimize, prevent and/or eliminate malodor associated with perspiration.
- the most common antiperspirant active ingredients typically used in these compositions are salts of strong inorganic acids, such as aluminium-containing and/or zirconium-containing salts. These salts upon contact with perspiration enter the sweat duct via diffusion or convection and react with the basic components of perspiration blocking it. Further, these antiperspirants and some other components of the composition often leaves a chalky film on the skin. When the composition dries on the skin or on clothing (which has come into contact with the skin after application of the antiperspirant), the antiperspirant salt often remains visible as a white residue. These white marks attack cellulosic fabrics due to liberation of strong acids from the salts, discolouring and ruining them over time, leaving the clothes with hard-to-remove stains. Besides, most of the antiperspirant compositions contain a high amount of oil components which increase the drying time upon contact with skin, providing an uncomfortable greasy and sticky feeling on application; and also leading to fabric staining.
