Carbomer 940 is a white loose powder. It has a spontaneous thickening performance, high transparency, high viscosity, strong suspending ability, rheological and thixotropic properties, low ion shear resistance, main characteristics It is swellable and slightly acidic. Widely used in transparent gel, essence and cream products, especially suitable for highly transparent products.
[Function and use]
Carbomer 940 has the characteristics of short rheology, high viscosity, high definition, 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 a higher viscosity in the case of very low content (conventional dosage 0.25-0.5%). Carbo resin can be used as an excellent suspending agent to suspend insoluble components in the system. It can also be used as an emulsifier, which plays an emulsifying and stabilizing role in the oil-water phase. In addition, it is also a transparent matrix for cosmetics and an effective water-soluble thickener.

[Usage Note]
After carbomer neutralization, long-term stirring or high-shear stirring will cause viscosity loss. The presence of electrolyte will lower the thickening efficiency of carbomer resin. Long-term ultraviolet irradiation will reduce the viscosity of carbomer resin.
