Message: | Carbomer is a loose white powder with a density of 208 kg / m3 and a glass transition temperature of 100-105 ℃. The molecule contains 56% - 68% carboxyl group, so the resin is weakly acidic. The pH of 0.5% aqueous dispersion is 2.7-3.5, its equivalent is 76 ± 4, and the equilibrium water content is 8-10% (relative humidity 50%). Many people have a familiar feeling about carbomer. Next, let's understand the function and application of carbomer.
To sum up, the characteristics of carbomer 940: it can produce high viscosity permanent emulsion and suspension, and the colloid produced has good transparency and short flow. Carbomer 934 features: good thickening effect, strong shear resistance, permanent stability at high viscosity, long flow in aqueous solution, it is suitable for cream cosmetics. The characteristics of carbomer 941: high efficiency thickening effect can produce clear and transparent water or alcohol water gel, and its rheological property is very short. Features of carbomer 1342: it has good resistance to ions in the system containing ions, and is more suitable for daily chemical and pharmaceutical fields |
