About this ingredient
Coco-Betaine is a mild amphoteric surfactant from coconut-oil fatty acids. Structurally similar to cocamidopropyl betaine (CAPB) but without the amide group – instead, direct fatty-acid-to-betaine bonds. As a result it less often contains DMAPA impurity (the main CAPB allergen). Where applied. Shampoos, shower gels, micellar products, baby cosmetics, intimate hygiene products. Concentration 1-10%. In Spain – in Klorane, Mustela, Babé Pediátrico, niche eco-cosmetic brands Mádara, Weleda. Mechanism. Amphoteric – gently solubilizes dirt and sebum. Works alongside anionic surfactants, reducing irritation. Stabilizes foam. Evidence base. Functional surfactant. No direct clinical efficacy. Tolerance profile is close to CAPB but with lower contact allergy risk due to the missing amide group and related impurities. Safety. CIR/SCCS confirm safety at cosmetic concentrations. Allergic reactions are rare, less frequent than for CAPB. Non-comedogenic. Pregnancy and lactation – safe. Acceptable at any stage. Suitable for baby cosmetics from birth. Suitable for. Universal, including atopics, eczema, sensitive skin. An alternative to CAPB with confirmed DMAPA allergy. Pharmacy atopic brands (La Roche-Posay Lipikar, Avène Trixera) often use coco-betaine instead of CAPB.
