Natrosol™ Cellulose Ethers

Key Applications

Hair Care; Oral Care; Skin Care

Product Description

This nonionic, water-soluble polymer is used to create products that are rich and thick from the container, but spread easily on hair and skin. Natrosol HEC is easily dissolved in cold or hot water to give crystal clear solutions of varying viscosities. Low to medium molecular weight (MW) types are fully soluble in glycerol and have good solubility in hydro-alcoholic systems containing up to 60 percent ethanol.

250 LR Natrosol 250 LR is an off-white powder that is surface-treated with glyoxal, a pH sensitive material that crosslinks hydroxyls on the particle surfaces and temporarily inhibits solubility.  This provides a pH and temperature sensitive delay, allowing the Natrosol HEC time to be dispersed as discrete particles before the particles begin to hydrate (swell and become sticky).  Once the glyoxal crosslinks hydrolyze, which is typically triggered by raising the pH, Natrosol HEC will begin to hydrate and dissolve without formation of lumps or gels.
