Cocamidopropyl Betaine is an amphoteric surfactant widely used to make cleanser systems milder.
It boosts foam and cleansing while reducing the harshness of stronger anionic surfactants. Most allergy issues attributed to it are linked to manufacturing impurities such as DMAPA/amidoamine rather than the ideal purified ingredient itself.
Usage & cautions
People with confirmed allergy to Cocamidopropyl Betaine or related impurities should avoid it.
Information approach
