COCAMIDOPROYPL BETAINE ●
TL;DR. This ingredient is an amphoteric surfactant used to boost foam, improve cleansing mildness, and help stabilize surfactant systems in shampoos, body washes, hand soaps, and facial cleansers.
What does COCAMIDOPROYPL BETAINE do in a cosmetic formula?
This ingredient is an amphoteric surfactant used to boost foam, improve cleansing mildness, and help stabilize surfactant systems in shampoos, body washes, hand soaps, and facial cleansers.
Is COCAMIDOPROYPL BETAINE clean?
From a clean-beauty perspective, it is generally accepted but watched because trace manufacturing residues can be linked with irritation or allergic contact dermatitis in sensitive users. Well-purified grades with tight residual-amine controls are the cleaner fit.
Is COCAMIDOPROYPL BETAINE sustainable?
This material is typically made from coconut or palm-kernel fatty acids combined with synthetic intermediates, so sourcing transparency matters. It is generally considered readily biodegradable, but palm-derived supply chains can carry land-use and certification concerns.
Is COCAMIDOPROYPL BETAINE COSMOS-approved?
It can be permitted under COSMOS-natural when made from approved renewable fatty-acid sources and compliant processing, but it is not a simple COSMOS-organic ingredient. Its Green Chemistry profile is mixed, with renewable carbon and good biodegradability balanced by multi-step synthesis and impurity-control needs.
How does COCAMIDOPROYPL 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, nonionic, and cationic systems. It is commonly used around 2 to 10% active matter in rinse-off cleansers, performs across roughly pH 4 to 8, and requires control of residual amines and amidoamine impurities for best skin compatibility.
