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.
Part of a system, not a label in isolation
It is commonly used in sticks and cream antiperspirants. It is not an aluminum salt and does not itself control sweating.
The regulatory assessment depends on the exposure scenario, including possible inhalation from aerosol products; the product format matters.
It is generally used for its sensory profile. The inhalation route is assessed separately for aerosols.
Do not confuse it with Dimethicone. Both are silicones, but their structures and volatility differ.
