What is Carbomer 940?
Carbomer is an organic compound, also known as polycarboxylate, which is a polymer formed by chemical crosslinking of acrylic acid or acrylate with allyl ether, including polyacrylic acid (homopolymer) and long-chain alkanol-acrylate polymer (copolymer). Its molecular structure contains 52~68% acid groups, so it has certain acidity, hydrophilicity and can be dissolved in water.

Application
Poly(Acrylic Acid) is a thickening, suspending, dispersing, emulsifying agent. In the cosmetic and textile printing fields, in printing inks, in emulsion-based lubricants, in pharmaceuticals, polishes, waxes, paints, waterproof and oil-proof coatings, in industrial specialties.
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 ethyl acetate and 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.
