Swapnroop offers Carbomer 980 NF as a pharmaceutical-grade excipient for formulation applications requiring high viscosity, efficient thickening, gel formation, rheology modification and suspension stabilization.
Carbomer 980 NF is a high-molecular-weight, crosslinked polyacrylic acid polymer classified as Carbomer Homopolymer Type C. It is a high-viscosity pharmaceutical excipient used in suitable topical, semisolid and other pharmaceutical formulation systems. Lubrizol's official specification identifies Carbopol 980 NF Polymer as meeting the applicable USP/NF, Ph. Eur., IP and ChP monograph requirements.
Carbomer 980 NF provides high viscosity at relatively low concentrations and is used as a functional rheology modifier, thickener and suspending agent. The official specification reports a viscosity range of 40,000–60,000 cP for a 0.5% w/w neutralized mucilage at 25°C. At 0.2% w/w, the specified viscosity range is 13,000–30,000 cP.
Within the Carbopol pharmaceutical polymer family, 980 NF is categorized as a homopolymer and is identified as a very-high-viscosity grade with high suspending ability and high mucilage clarity.
