Coco-Betaine ●
TL;DR. This ingredient is a mild amphoteric surfactant used in cleansers to lift oil and soil, boost foam, and reduce the feel of stronger anionic cleansing systems.
What does Coco-Betaine do in a cosmetic formula?
This ingredient is a mild amphoteric surfactant used in cleansers to lift oil and soil, boost foam, and reduce the feel of stronger anionic cleansing systems.
Is Coco-Betaine clean?
From a clean beauty perspective, it is generally accepted but not entirely friction-free because it is synthetically processed and can irritate sensitive skin at higher active levels, especially in rinse-off formulas with multiple surfactants. It is not a major restricted-list ingredient, but quality and residual processing byproducts matter.
Is Coco-Betaine sustainable?
This material is typically made from coconut or palm-derived fatty chains combined with synthetic chemistry, so sourcing traceability is the main sustainability question. It is expected to be readily biodegradable, though its overall profile depends on feedstock certification and wastewater exposure from rinse-off use.
Is Coco-Betaine COSMOS-approved?
It can be permitted under COSMOS-natural when the feedstocks, manufacturing steps, and impurity profile meet the standard’s surfactant criteria, but it does not usually contribute to organic percentage. Its Green Chemistry fit is moderate, with renewable carbon content and biodegradability balanced against multi-step chemical processing.
How does Coco-Betaine work chemically?
The molecule is an amphoteric, zwitterion-forming surfactant with a long fatty chain and a polar head group, which helps it remain compatible with anionic, nonionic, and cationic systems. It is commonly used in rinse-off products across mildly acidic to neutral pH ranges, where it supports foam quality, viscosity building with salt or partner surfactants, and a milder skin feel.
