About

A skin-conditioning fatty alcohol that is structurally related to stearyl alcohol, providing emolliency and helping to stabilize emulsions.

Tetradecyloctadecanol is a long-chain saturated fatty alcohol consisting of a C14 alkyl chain (tetradecyl) attached to a C18 alcohol (octadecanol). It functions as an emollient, emulsifier, and viscosity-controlling agent. Fatty alcohols of this type are considered inert and non-irritating, making them suitable for sensitive skin formulations. Stearyl alcohol analogues like this are widely used in cosmetics and have no EU restrictions. The ingredient is not metabolically active and acts purely as a structural/occlusive emollient.

Skin benefits

  • Occlusive emollient barrier
  • Stabilizes emulsions
  • Conditions and softens skin

Known concerns
