What does this ingredient do in an antiperspirant?

It is a volatile base ingredient that makes application easier and then largely evaporates from the skin's surface.

It is commonly used in sticks and cream antiperspirants. It is not an aluminum salt and does not itself control sweating.

Regulatory and scientific context

The regulatory assessment depends on the exposure scenario, including possible inhalation from aerosol products; the product format matters.

What sensitive skin should consider

It is generally used for its sensory profile. The inhalation route is assessed separately for aerosols.

Do not confuse with

Do not confuse it with Dimethicone. Both are silicones, but their structures and volatility differ.

Links are based on the complete published INCI list for the exact product version.
