Carbomer 940
Carbomer 940 is a white loose powder. It has excellent thickening properties, high transparency, high viscosity, strong suspending ability, short rheology and thixotropy, and low resistance to ionic shear force. Main characteristics Reflected in swelling and slightly acidic properties. It is widely used in transparent gel, essence and cream products, especially suitable for highly transparent products.
Carbomer 940 has the characteristics of short rheology, high viscosity, high clarity, low ionic resistance and shear resistance. Its role in the product is mainly reflected in three aspects: thickening, suspension and emulsification. Carbo 940 can produce higher viscosity at a very low content (regular dosage 0.25-0.5%).
Application:
Widely used in transparent gel, essence and cream products, especially suitable for highly transparent products.
