description Product Description
Used as a binder in pharmaceutical tablets to ensure active ingredients are evenly distributed and released properly. Acts as a stabilizer in colloidal systems, preventing particles from clumping in solutions. Employed in wound care products due to its film-forming and moisture-retaining properties. Commonly found in eye drops to reduce irritation and improve lubrication. Used in hair and skin care products for its ability to hold moisture and improve texture. Serves as a dispersing agent in pigments and dyes for inks and coatings. Also utilized in membrane filtration processes to enhance performance and reduce fouling.
