Calcium Stearate

What Calcium Stearate is & what it does

A soft metallic soap used to add slip and a smooth feel and to help bind powders. It improves texture and water resistance.

What does Calcium Stearate do in skincare?

Calcium Stearate is the calcium salt of stearic acid and is used mainly as a thickener, anticaking, and texture agent. It helps stabilize formulas and can give powders and creams a smooth, even feel.

Is Calcium Stearate comedogenic?

Calcium Stearate is generally used at low levels as a texture and stabilizer ingredient and is not commonly singled out as pore-clogging. Since reactions vary by person and full formula, those prone to breakouts can monitor how their skin responds.

Is Calcium Stearate vegan?

Calcium Stearate can be made from either plant or animal sourced stearic acid, so its vegan status depends on the source. Brands using plant-derived stearic acid can offer a vegan-friendly version, so check with the manufacturer if this matters.
