Product Name:Carbomer 940
English Name:Carbomer 940
CAS No.:76050-42-5
Aliases:Carbomer, Carbopol 940
Molecular Formula:(C3H4O2)n
Physical Properties:White loose powder, slightly acidic, with a slight characteristic odor and strong hygroscopicity. It swells easily in water and polar organic solvents (such as ethanol and glycerol). After neutralization it forms clear gels. Density: 0.21 g/cm³; pH (0.5% aqueous solution): 2.7-3.5; viscosity (0.5% aqueous solution): 40000-60000 mPa·s; glass transition temperature: 100-105°C; carboxyl content: 56%-68%.
Uses:Carbomer resin is used as an excellent suspending, stabilizing, emulsifying and thickening agent. It is widely used in cosmetics as a transparent matrix and rheology modifier for creams, gels and lotions, as well as a pharmaceutical excipient matrix. The recommended dosage is generally 0.2%-1.0%, and 0.2%-0.5% for thickening or gel applications.
