What Aluminum Chlorohydrate does

Reduces sweat at the surface of the skin
Forms a temporary gel inside sweat ducts
Works as the active in antiperspirants

Aluminum chlorohydrate is made by reacting aluminum compounds with hydrochloric acid, creating a water-soluble salt. It belongs to the aluminum salt family, a group that antiperspirants have relied on for decades.

Formulators use it because it dissolves easily in water and, once it meets sweat, forms a gel-like plug in the sweat ducts. This helps lower how much sweat reaches the skin. In roll-ons and sticks it usually feels smooth, though it can leave a slight tacky film as it dries. Some people notice mild stinging, especially on freshly shaved skin.

Good for

Good for people who want to reduce underarm sweat and are looking for an antiperspirant rather than a deodorant alone.

Be careful if

Nothing in particular for most skin types.

Frequently asked questions

Is aluminum chlorohydrate safe to use?

It has been used in antiperspirants for a long time and is generally well tolerated by most people. Skin sensitivity varies, so if you notice redness or itching, stop using the product and check with a doctor or pharmacist.

Is aluminum chlorohydrate the same as deodorant?

Not quite. Deodorants mainly mask odor, while antiperspirants like this one aim to reduce sweat. Many products combine both, so check the label if you want sweat reduction.
