Aqua is the scientific name for water. It is commonly used as a solvent in antiperspirants. It helps to improve the spreadability of the product on the skin, allowing other ingredients to be distributed more effectively.

Alcohol Denat is one of the short-chain alcohol types and is commonly found in the ingredients of antiperspirants and deodorants. While antiperspirants reduce sweating, deodorants help mask or prevent body odor without affecting sweating. Alcohol Denat can assist in stabilizing the formulation of antiperspirants or deodorants, drying and cleansing the skin, and ensuring quick drying of the product on the skin. Additionally, it may help prevent the formation of bacteria and odor.

Aluminum chloride is one of the active ingredients in antiperspirant products. It helps reduce sweating by temporarily blocking sweat glands. This prevents sweat from reaching the skin's surface, thereby helping to prevent the formation of body odor and avoiding stains on clothes caused by sweat contact with the skin.
