Cocamidopropyl Betaine ●
TL;DR. This ingredient is an amphoteric surfactant used for gentle cleansing, foam boosting, and improving the feel of rinse-off formulas. It also helps reduce the harsh feel of stronger anionic surfactants and can support viscosity building in shampoos and body washes.
What does Cocamidopropyl Betaine do in a cosmetic formula?
This ingredient is an amphoteric surfactant used for gentle cleansing, foam boosting, and improving the feel of rinse-off formulas. It also helps reduce the harsh feel of stronger anionic surfactants and can support viscosity building in shampoos and body washes.
Is Cocamidopropyl Betaine clean?
From a clean-beauty perspective, this ingredient is widely accepted but not friction-free. The main scrutiny is around manufacturing residues, especially residual amines, which can increase irritation potential if not tightly controlled.
Is Cocamidopropyl Betaine sustainable?
This material is typically made from coconut or palm-derived fatty acids combined with synthetic inputs. It is generally considered readily biodegradable, but its plant-oil sourcing can carry traceability and land-use concerns.
Is Cocamidopropyl Betaine COSMOS-approved?
It can be used in COSMOS-natural formulas when the supplier and manufacturing route meet the standard’s criteria, but it does not contribute to COSMOS-organic content in the way minimally processed plant ingredients do. Green Chemistry alignment is mixed, with renewable fatty feedstock and biodegradability balanced against chemical modification and residue control requirements.
How does Cocamidopropyl Betaine work chemically?
The molecule is a zwitterionic surfactant with a fatty amide tail and a it-type head group, which helps it interact well with both water and oil while remaining compatible with many surfactant systems. It is commonly used around 3 to 10% as supplied in cleansing products, performs well across mildly acidic to neutral pH, and is often paired with anionic surfactants for foam and mildness.
