1. Product description
CARBOMER 940 is a crosslinked acrylic polymer with strong hygroscopicity, acting as high-efficient thickener and suspending agent with outstanding stability and excellent clarity. CARBOMER 980 can be used in products including clear gels, topical lotions and creams. They primarily function as efficient thickeners and binders and provide suspension of non-soluble actives or excipients. Transparent hydroalcoholic and sanitizing gels can be manufactured based on CARBOMER 980 for its good compatibility with ethanol.
