Hydroxypropylcellulose (HPC)

CAS No. 9004-64-2

Hydroxypropylcellulose (HPC) is a nonionic, water-soluble cellulose ether with a versatile combination of properties in personal care applications. It combines solubility in aqueous and polar organic solvents, thermoplasticity, and surface activity with the thickening and stabilizing properties of other water-soluble cellulose polymers.

One of the problems normally associated with this and other water-soluble thickeners is the tendency of the particles to agglomerate or lump when first wetted with water. The high-purity cosmetic grade of Hydroxyethylcellulose we offer is an R-grade, designed to be added to water without lumping, and thus greatly facilitating solution preparation. It is also the most efficient grade of non-ionic thickener available from the manufacturer.

HPC is great for hand sanitizers, hair styling products, body care, facial care, color cosmetics, and after sun care
