Coco-Betaine
A mild cleanser made from coconut. It boosts foam and softens the effect of stronger cleansers in the same product.
What it does
It’s made from coconut fatty acids. It’s there to clean, not to change your skin.
The EU’s ingredient database lists it as a thickener (controls how thick the product is) and a cleanser (helps keep skin clean).European Commission, CosIng (© European Union, CC BY 4.0) · uses put in plain words by Drop ↗
The evidence, graded
expert consensusUS safety reviewers (2018) judged 11 alkyl betaines, coco-betaine among them, safe as used in products made not to irritate. Tests at up to 5% found it didn’t cause allergy, and in a human study it irritated less than SLS. Two people got eczema after shampoos with it, and patch tests pointed to coco-betaine. It irritated rabbit eyes at 16% and 30%.Burnett 2018 · International Journal of Toxicology ↗
