What is the active ingredient commonly found in anti-perspirants?

Aluminum chloride is widely recognized as the active ingredient in many anti-perspirants. Its primary function is to block sweat glands, effectively reducing perspiration. When applied to the skin, aluminum chloride forms a temporary gel that acts as a barrier. This action prevents sweat from reaching the skin's surface, which is particularly valuable in areas prone to excessive sweating, such as the underarms.

The efficacy of aluminum chloride is well-documented, and it’s often the key active agent in formulations designed for strong or clinical-level antiperspirants. Its use is supported by numerous studies and industry standards, making it a trusted ingredient in personal care products aimed at controlling moisture and odor associated with sweating.
