Carbomer is a polymer polymer that bonds acrylic tetrenolyl ether or acrylic sucrose. According to the calculation of dry products, the acid-containing acid (-COOH) should be 56.0% to 68.0%. Kapom is a very important rheum regulation agent, with water binding gel is acidic, neutralized and after Kapo is an excellent gel matrix, thickening, suspension and other important uses, simple process, good stability, widely used in emulsions, creams, gels.  

Polyacrylic acid with low molecular weight is a colorless and transparent solid. Its 20% to 30% aqueous solution is a pale yellow or colorless viscous liquid. Molecular weight 500 to 5000, pH is 2 to 4. The solution constant is about 5× 10-5, and the solution constant of acetic acid is similar (1.8× 10-5), which is much larger than the first dissociation constant of carbonic acid. Therefore, polyacrylic acid is a weak acid stronger than carbonic acid. It is generally stable for strong acids, strong alkalis, oxidants, but at high temperatures or long-term light, low molecular weight polyacrylic acid will still re-polymerize, so that its molecular weight continues to increase, viscosity also increases, and finally become a frozen state of solids from the water solution. It is a chelating agent and a lattice distortion agent, which can form a stable complex with metal ions such as calcium and magnesium in water. It also has good dispersion properties, can disperse crystalline compounds in water, soil, dust, corrosive substances and biological debris and other non-stereotyped particles.
