Safety score · 0–100

Good

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A natural skin lipid that softens and protects the barrier. Very well tolerated; the only real downside is that the unhydrogenated form can oxidize, so squalane is often preferred.
