Carbomer 351

Product Name: Carbomer 351

Ingredient:Acrylic polymer  CAS NO.: 9003-01-4  HS code: 39061000.00

Introduction

It is a crosslinked acrylic polymer with strong hygroscopicity, acting as high-efficient thickener and suspending agent with outstanding stability and excellent clarity. TC-CARBOMER 351 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 351 for its good compatibility with ethanol.
