What it does
The EU lists it as a skin and hair conditioner that holds water and also cleanses.
The evidence, graded
expert consensusUS safety reviewers (2017) looked at 115 ingredients made from amino acids, which mainly condition skin and hair or cleanse. This one is on their list. They judged the group safe as used, as long as the product is made not to irritate, since most cleansing ingredients irritate a little. For the ones made with triethanolamine (TEA), they said leftover diethanolamine (DEA) must stay within the level they judge safe. Sodium caproyl prolinate and palmitoyl isoleucine weren’t in use then.Burnett 2017 · International Journal of Toxicology ↗
