Aluminum chloride and aluminum chlorohydrate are not the same

Both ingredients are antiperspirant actives, but they are usually used in different types of formulas and routines. Comparing products by a familiar word on the label alone is not enough.

Editorially reviewed · 10 September 2026

Aluminum chlorohydrate

It is commonly found in daily roll-ons and aerosols. These products are usually applied in the morning or after washing unless the manufacturer states otherwise.

Aluminum chloride

It is commonly used in long-lasting overnight products. Completely dry, intact skin, a thin layer and a waiting period after hair removal are especially important with these formulas.

What matters more than the name

Tolerance is influenced by concentration, solvent, acidity, other ingredients and application technique. That is why we show the active ingredient alongside the complete formula and its source whenever available.
