Cocobetaine is one of the sugar surfactants and has a pH value between 5 and 6. It is particularly easily absorbed by the skin and mucus membranes. Despite its mildness, it has good foaming and cleaning properties and is therefore ideal for baby products and cleaning products for sensitive skin. A slightly anti bactericidal effect can be attributed to cocobetaine. Cocobetaine is mainly found in shampoos, shower gels, intimate washing lotions, bubble baths and liquid soaps and can also reduce the irritation potential of other surfactants.
