Sodium Stearoxy Pg-Hydroxyethylcellulose Sulfonate
What is Sodium Stearoxy Pg-Hydroxyethylcellulose Sulfonate?
Sodium Stearoxy PG-Hydroxyethylcellulose Sulfonate is a synthetic anionic polymer derived from cellulose, a plant-based polysaccharide. It features hydroxyethyl ether groups for water solubility, propylene glycol (PG) and stearoxy modifications for lipophilicity, and sulfonate groups for charge and compatibility. Primarily used in rinse-off cleansing products like shampoos, conditioners, and body washes, as well as some emulsions, it acts as a rheology modifier. In formulations, it hydrates and swells in aqueous systems, creating a three-dimensional network that boosts viscosity, prevents phase separation, suspends solids or droplets, and enhances shear-thinning behavior for better dispensing and rinse-off. The hydrophobic stearoxy chain aids mild deposition on surfaces, while sulfonation ensures stability with anionic surfactants, contributing to creamy textures and improved user experience across personal care categories.
