    Carbomer is a loose white powder, with acidity, hygroscopicity and special slight odor. It can be dissolved in water, ethanol and glycerol. The molecule contains 56% – 58% carboxyl group, so it is weakly acidic. When carbomer is dispersed in water, due to the repulsion between negative charges caused by carboxyl ionization, the crimped polymer stretches out and expands in volume. The pH of 0.5% aqueous dispersion is 2.7 ~ 3.5. 1% aqueous dispersion can be neutralized with alkaline substances to form gel. The concentration of commonly used aqueous dispersion is 0.1% – 3.0%.

    1.The main functions of carbomer are thickening, suspension and emulsification,
    2.In pharmaceutics, it can be used as gel agent, adhesive, coating material, rheological modifier (humidifier, lubricant, suspension aid, stabilizer), etc., and is widely used, especially in new drug delivery systems. It has been widely used at home and abroad.

    At present, our factory has upgraded carbomer 940 to carbomer 980. Because the original Carbomer 940 is synthesized from acrylic acid and benzene, it contains a certain amount of benzene residue, which is a toxic substance.
    In order to be safer, we use cyclohexane to make Carbomer 980, so that our product ingredients will be safer and the effect will be better.
    Of course, Carbomer 980 is the same as Carbomer 940 in terms of viscosity and light transmittance.
    If you have no special requirements on light transmittance and viscosity, we also recommend Carbomer 680, the price will be cheaper.
