TEA-Cocoyl Alaninate
TEA-Cocoyl Alaninate
Alanine joined to coconut fatty acids, as a triethanolamine salt: a cleanser.
What it does
The EU lists it as a cleanser that also conditions hair.
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 ↗
expert consensusEU Regulation 1223/2009, Annex III entry 62, covers trialkylamines, trialkanolamines and their salts. It caps them at 2.5% in leave-on products and sets no maximum for rinse-off products. TEA-cocoyl alaninate and TEA-cocoyl glutamate are triethanolamine salts.EU 2026 · Official Journal of the European Union (consolidated version, EUR-Lex) ↗
