Sorbeth-30 Tetraoleate

Sorbeth-30 Tetraoleate

A helper that keeps oil and water mixed so a product stays blended.

What it does

It’s sorbitol joined to a PEG chain and four chains of oleic acid, a fatty acid. It’s there to hold the formula together, not to change your skin.

The evidence, graded

expert consensusUS safety reviewers (2015) assessed 80 polysorbates, which products use mostly as surfactants, helping oil and water mix. Polysorbate 20, 60 and 80 and sorbeth-30 tetraoleate are named in their conclusion. They judged the polysorbates safe as used, in products made not to irritate, replacing their earlier verdicts.Becker 2015 · Cosmetic Ingredient Review ↗
