About

A saturated, hydrogenated form of lanosterol — works as a skin-conditioning emollient similar to lanosterol but more chemically stable due to its saturated sterol ring structure.

Dihydrolanosterol (also called lanostanol) is the saturated analogue of lanosterol, lacking the double bonds in the lanostane tetracyclic ring system. It is obtained by hydrogenation of lanosterol. Like other sterols, it functions as a skin-conditioning agent and emulsifier in cosmetic products. It is well tolerated on skin, has a favorable safety profile, and is not restricted or banned in any major regulatory jurisdiction.

Skin benefits

  • Skin-identical emollient — reinforces barrier function
  • Stable saturated sterol — good for sensitive skin formulations

Known concerns

  • Minor: derived from lanolin, potential for lanolin allergy in sensitized individuals
