Cetyl Hydroxethylcellulose ●
TL;DR. This ingredient is a nonionic thickener, rheology modifier, and emulsion stabilizer. It helps water-based formulas build viscosity, suspend particles, and improve cushion without adding oiliness.
What does Cetyl Hydroxethylcellulose do in a cosmetic formula?
This ingredient is a nonionic thickener, rheology modifier, and emulsion stabilizer. It helps water-based formulas build viscosity, suspend particles, and improve cushion without adding oiliness.
Is Cetyl Hydroxethylcellulose clean?
From a clean-beauty perspective, it is generally low-irritation and not a common allergen or restricted-list concern. The main scrutiny is supplier quality, since manufacturing can require controls for trace processing residues.
Is Cetyl Hydroxethylcellulose sustainable?
This material is based on cellulose, usually from wood pulp or cotton, with an added fatty chain that may be plant-derived or petrochemical depending on the supplier. It is more biodegradable than many synthetic polymers, but its chemical modification makes its environmental profile less direct than native plant gums.
Is Cetyl Hydroxethylcellulose COSMOS-approved?
It can be permitted in COSMOS-natural formulations when the supplier documents compliant sourcing, processing, and residual controls, while it does not itself contribute meaningfully to organic content. Its Green Chemistry fit is moderate, with renewable cellulose as a backbone but additional chemical modification and residue management requirements.
How does Cetyl Hydroxethylcellulose work chemically?
It is a high-molecular-weight, nonionic plant-polymer derivative with water-loving ether groups and sparse long alkyl side chains, so it thickens through chain entanglement plus weak associative networking. Typical use is about 0.1% to 1.0%, with broad pH stability in many emulsions and gels, and hydration depends on good dispersion before full water swelling.
