Hydroxypropylcellulose ●
TL;DR. This ingredient is primarily a thickener, film-former, and binder that helps build viscosity, improve spread, and stabilize water-based formulas. It is common in gels, creams, mascaras, hair styling products, and oral-care formats.
What does Hydroxypropylcellulose do in a cosmetic formula?
This ingredient is primarily a thickener, film-former, and binder that helps build viscosity, improve spread, and stabilize water-based formulas. It is common in gels, creams, mascaras, hair styling products, and oral-care formats.
Is Hydroxypropylcellulose clean?
From a clean-beauty perspective, it is generally well tolerated, low in sensitization concern, and not a common restricted-list trigger. The main caveat is that it is a chemically modified natural polymer rather than a minimally processed botanical material.
Is Hydroxypropylcellulose sustainable?
This material is based on a plant-derived polysaccharide backbone, with chemical modification used to make it more useful in formulas. It is generally considered biodegradable and has lower persistence concern than many fully synthetic film-forming polymers.
Is Hydroxypropylcellulose COSMOS-approved?
It can be permitted under COSMOS-natural and COSMOS-organic frameworks when it meets the standard’s raw-material and processing criteria, though it does not contribute organic content. Its Green Chemistry profile is favorable because of its renewable backbone and biodegradability, with a modest tradeoff from the chemical etherification step.
How does Hydroxypropylcellulose work chemically?
The molecule is a nonionic, water-soluble polysaccharide ether with a substituted glucose-unit backbone, so it thickens through hydration and chain entanglement rather than charge effects. Typical use is about 0.1% to 2% for viscosity and film benefits, it is broadly stable across mildly acidic to alkaline pH, and its nonionic character gives good compatibility with many salts and surfactants.
