Swapnroop offers Carbomer 990 NF as a pharmaceutical excipient for formulation applications requiring viscosity modification, thickening, gel formation, suspension stabilization and rheological control.
Carbomer is a synthetic, high-molecular-weight, crosslinked polymer of acrylic acid used as a functional pharmaceutical excipient. Depending on polymer grade and crosslinking characteristics, carbomers can provide different viscosity, suspending, gel-forming and rheological properties.
Carbomer excipients are used in pharmaceutical formulation development across topical, semisolid, liquid and other suitable dosage-form applications. Lubrizol describes pharmaceutical Carbopol polymers as functional excipients used for viscosity control, rheology modification, thickening, gel formation, suspension stabilization and bioadhesive applications.
Carbomer 990 NF can be positioned as a pharmaceutical excipient for formulations where controlled viscosity and rheological performance are required.
Carbomer polymers swell and develop viscosity following appropriate dispersion and neutralization. Their performance depends on polymer grade, concentration, neutralization conditions, electrolytes, formulation pH and other formulation components.
Because 990 NF is not listed among the current official Lubrizol Carbopol pharmaceutical grades, the exact viscosity and other numerical specifications should be taken from the actual manufacturer's approved specification for your Carbomer 990 NF material rather than being copied from another Carbomer grade.

*CAS 9003-01-4 is widely associated with Carbomer/polyacrylic acid polymers, but the CAS number should be confirmed against the specific 990 NF manufacturer's CoA/SDS before publication.
Carbomer excipients can be used in suitable pharmaceutical formulation systems for:
Carbopol pharmaceutical polymers are used in topical and semisolid formulations because they provide efficient thickening, viscosity control, gel formation and stabilization of dispersed ingredients.
Depending on the exact grade, Carbomer 990 NF may provide:
The performance of an individual carbomer grade should be established using its actual technical specification and formulation compatibility testing.
Carbomer pharmaceutical excipients are typically evaluated using appropriate identification and physicochemical tests.
Depending on the specific grade, quality testing can include:
For example, current official Carbopol pharmaceutical specifications use carboxylic-acid content, viscosity, loss on drying and residual-solvent testing as important quality parameters.
Swapnroop provides pharmaceutical excipients for formulation development and manufacturing requirements. Carbomer 990 NF can be positioned for customers seeking a pharmaceutical carbomer for viscosity modification, gel formation, suspension stabilization and suitable topical or semisolid formulation applications.
Product grade, specifications, packaging and technical documentation can be aligned with customer requirements and applicable regulatory standards.
Carbomer 990 NF should be stored in tightly closed packaging and protected from moisture and contamination.
Storage and handling should follow the applicable manufacturer's product specification and Safety Data Sheet. Appropriate precautions should be followed when handling fine polymeric powder.
Depending on customer and regulatory requirements, documentation may include:
