Sodium carbomer

Sodium carbomer (CAS 73298-57-4), also known by the E-number E1210, is a pre-neutralized polyacrylic acid polymer used as a rheology modifier and stabilizer.

Where is Sodium carbomer used?

• Personal care: viscosity builder and suspending agent in gels, lotions and cleansers
• Pharmaceutical: thickener and binder in topical gels and ophthalmic formulations
• Coatings and adhesives: thickening and stabilizing agent for water-based dispersions
• It also supports emulsion stability in leave-on and rinse-off cosmetic products.

Good to know: Unlike standard carbomers that require in-process neutralization, the sodium salt form disperses readily in aqueous systems, streamlining manufacturing workflows and reducing production time.

Commercial specifications

• Cosmetic-grade and pharmaceutical-grade specifications; the latter conforming to Ph. Eur. and USP monograph requirements
• Technical-grade material for industrial coating and adhesive applications where pharmacopoeial compliance is not required
