Carbopol 940

Efficient Thickener

Carbomer 940 is a white loose polymer with slightly acidic and hygroscopic properties. It is soluble in water, ethanol and glycerol. It is obtained by bonding allyl sucrose or pentaerythritol allyl ether with acrylic acid. It has high thickening performance, high transparency, high viscosity, strong suspension ability, and low resistance to ionic shear force.

- Benzene-Free System - Excellent Suspending - High Viscosity - Low Resistance To Ionic Shear Force -Formulation Flexibility - High Light Transmittance

Carbomer 940 is a high-purity, cross-linked acrylic polymer renowned for its unparalleled ability to create crystal-clear gels in aqueous and hydroalcoholic systems (≤60% ethanol). As a rheological modifier, it delivers exceptional thickening efficiency at low concentrations (0.5%-2%), achieving viscosities up to 60,000 mPa·s (1% neutralized solution). Its unique molecular architecture ensures zero cloudiness or residue, making it the gold standard for luxury serums, transparent hydrogel masks, and premium ophthalmic formulations. The pseudoplastic behavior enables smooth application while maintaining structural integrity during storage.

Why choose Carbomer 940?

As the benchmark for clarity and thickening efficiency in the carbomer family, Carbopol® 940 has been successfully used in over 10,000 formulations worldwide and serves as the hidden formula engine for leading brands like Estée Lauder and L'Oréal. Whether developing transparent serums embracing the "clean beauty" trend or demanding medical-grade gels, it delivers a 100% performance breakthrough at just a 1% addition level.
