Choleth-24
Keeps oil and water mixed and keeps a product stable.
What it does
It’s the cholesterol part of lanolin, the wax from sheep’s wool, joined to a PEG chain, so it mixes with both oil and water. It’s there for texture and stability, not to change your skin.
The evidence, graded
expert consensusUS safety reviewers’ 1982 report describes choleth-24, made from the cholesterol part of lanolin, as used to help oil and water mix and keep products stable, at up to 5%. On people’s skin it was only slightly irritating and caused no allergy at up to 50%, and the reviewers judged it safe as used. In 2023 they looked again and kept that verdict.Cosmetic 1982 · Journal of the American College of Toxicology 1(4):119-126 (CIR portal copy) ↗
