What Stearyl Alcohol does

Thickens and gives body to formulas
Softens and smooths skin and hair
Helps oil and water stay blended

Stearyl Alcohol belongs to a group called fatty alcohols. These are long, waxy molecules, not the drying alcohol used in some toners or the drinking kind. It is typically made from plant or animal fats.

Formulators use it to add body and a cushiony feel. It helps water and oil mix into a stable cream, and it can give shampoos and conditioners a softer, slightly opaque look. On skin and hair it leaves a smooth, lightly conditioning feel rather than a greasy film. Because it is solid at room temperature, it helps creams set into a comfortable texture.

Good for

Suits people who want creamy, smooth-feeling products with a soft, not sticky, finish. It is found in many everyday formulas.

Frequently asked questions

Is Stearyl Alcohol the same as drinking alcohol?

No. Stearyl Alcohol is a fatty alcohol, a waxy molecule with a long carbon chain. It is not the drinking kind, and unlike quick-drying short-chain alcohols such as ethanol, it is used to soften and smooth.

Is Stearyl Alcohol bad for your skin or hair?

For most people it is considered gentle and well tolerated. It is used to soften and condition, and it is rarely linked with irritation. Anyone with sensitive skin or a known reaction should patch test new products first.
