Cocomidopropyl Betaine ●
TL;DR. This ingredient is an amphoteric surfactant used in shampoos, body washes, facial cleansers, and hand soaps to boost foam, improve mildness, and help thicken surfactant blends.
What does Cocomidopropyl Betaine do in a cosmetic formula?
This ingredient is an amphoteric surfactant used in shampoos, body washes, facial cleansers, and hand soaps to boost foam, improve mildness, and help thicken surfactant blends.
Is Cocomidopropyl Betaine clean?
This ingredient is widely used in clean-positioned cleansing formulas, but it has a known sensitization caveat tied mainly to residual amidoamine and DMAPA from manufacturing. Good supplier purification and impurity specifications matter more than the base molecule itself.
Is Cocomidopropyl Betaine sustainable?
This material is commonly made from coconut or palm-kernel fatty acids combined with synthetic processing chemistry. It is readily biodegradable, but its sourcing profile can carry palm-related traceability concerns.
Is Cocomidopropyl Betaine COSMOS-approved?
It is generally permitted in COSMOS-natural and COSMOS-organic finished products when it meets the standard’s surfactant and biodegradability requirements. From a Green Chemistry view, it has partial alignment because it uses renewable fatty feedstocks and biodegrades, but it is still a chemically transformed surfactant with impurity-control needs.
How does Cocomidopropyl Betaine work chemically?
The molecule is a zwitterionic amphoteric surfactant with a fatty amide tail and a it head group, which helps it pair well with anionic surfactants and reduce cleanser harshness. Typical active use levels are about 2 to 10% in rinse-off products, and it is stable across mildly acidic to neutral cleanser pH ranges, often around pH 5 to 7.
