HPC ●
TL;DR. This ingredient is primarily a nonionic thickener, film-former, and binder. It helps build gel texture, suspend particles, improve spread, and leave a light flexible film on skin or hair.
What does HPC do in a cosmetic formula?
This ingredient is primarily a nonionic thickener, film-former, and binder. It helps build gel texture, suspend particles, improve spread, and leave a light flexible film on skin or hair.
Is HPC clean?
It is generally viewed as low-irritation and low-sensitization in clean beauty frameworks. The main quality consideration is control of manufacturing residues rather than routine skin reactivity.
Is HPC sustainable?
It is based on renewable plant fiber that is chemically modified, usually with some petrochemical input. It is generally more biodegradable than persistent silicone-type polymers, although breakdown rate depends on substitution level and wastewater conditions.
Is HPC COSMOS-approved?
It is permitted under COSMOS natural and organic standards when it meets the standard’s origin and processing requirements. From a Green Chemistry view, it has a renewable backbone and works at low levels, balanced by chemical derivatization and reagent controls.
How does HPC work chemically?
The molecule is a nonionic, water-soluble, substituted plant-fiber polymer with ether-linked side groups that reduce crystallinity and allow hydration in water and many water-alcohol systems. Typical use is about 0.1 to 2% as a rheology modifier or film former, with good stability around pH 3 to 11 and possible viscosity loss under strong oxidizing conditions or very high electrolyte load.
