Swapnroop offers Carbomer 980 as a pharmaceutical-grade excipient for formulation applications requiring high viscosity, gel formation, rheology modification, suspension stabilization and controlled formulation consistency.
Carbomer 980 is a high-molecular-weight, crosslinked acrylic acid polymer classified as Carbomer Homopolymer Type C. It is widely used as a functional pharmaceutical excipient because of its high thickening efficiency and ability to develop substantial viscosity at low concentrations after neutralization. The pharmaceutical-grade Carbopol 980 NF specification identifies it as a white, fluffy powder with a slightly acetic odor.
Carbomer 980 NF is designed for pharmaceutical formulations where high viscosity and efficient rheology modification are required. At a 0.5% concentration, neutralized to pH 7.3–7.8, the published specification gives a viscosity range of 40,000–60,000 cP at 25°C. At 0.2% concentration under the specified test conditions, the viscosity range is 13,000–30,000 cP.
Lubrizol categorizes Carbopol 980 NF as a homopolymer and identifies it as a very-high-relative-viscosity carbomer with high suspending ability and high mucilage clarity. It is used in pharmaceutical topical and oral formulation applications.

Carbomer polymers are crosslinked acrylic-acid polymers designed to provide viscosity enhancement, suspension properties and gel-forming functionality.
Carbomer 980 can be used in pharmaceutical formulation development for applications such as:
Lubrizol identifies Carbopol polymers for topical applications including clear gels, hydroalcoholic gels, lotions and creams, and lists 980 NF among the very-high-viscosity grades.
Carbomer 980 provides efficient viscosity development at relatively low concentrations. Its formulation functionality can help pharmaceutical developers achieve:
The published pharmaceutical comparison identifies Carbopol 980 NF as having very high relative viscosity, high suspending ability and high mucilage clarity.
Pharmaceutical-grade Carbomer 980 is evaluated using identification and physicochemical tests appropriate for the polymeric excipient.
The published Carbopol 980 NF specification includes:
The specification gives 56.0–68.0% carboxylic acid content, 40,000–60,000 cP viscosity at 0.5%, 13,000–30,000 cP at 0.2%, and NMT 2.0% loss on drying.
Swapnroop provides pharmaceutical excipients for formulation development and manufacturing requirements. Carbomer 980 can be positioned for customers requiring a high-viscosity carbomer for pharmaceutical gels, topical formulations, suspension systems and other suitable formulation applications.
Material specifications, grade requirements, documentation and packaging can be aligned with applicable customer and regulatory requirements.
Carbomer 980 should be stored in tightly closed packaging and protected from moisture, contamination and unsuitable environmental conditions.
The material should be handled according to the applicable product specification and Safety Data Sheet. Appropriate precautions should be taken when handling fine polymeric powder.
