Thickener

PRODUCT NAME：Carbomer 940

Carbomer 940 is a cross-linked polyacrylate polymer used in personal care gels and creams as a high-efficient rheology modifier. It is capable of providing high viscosity, excellent thickening and suspending performance with low-dosage. Its short flow (non-drip) properties are ideal for applications such as clear gels, hydroalcoholic gels, creams. When neutralized by alkali it forms sparkling clear water or hydroalcoholic gels and creams.

Formula Guidelines:

Typical recommended dosage at 0.2-1.0 wt %. 

To disperse Carbomer 940 completely, it should be slowly and carefully sprinkled to dispersion medium while the mix is stirred rapidly to avoid formation of lumps; extremely high shear rate mixer should be carefully employed to avoid viscosity loss. 

The ideal viscosity can be achieved at pH ranges of 5.0～10.0 when neutralized;

In a hydoalcoholic system, a correct neutralizer must be chosen carefully based on the amount of alcohol to be gelled. 

After neutralization, high-shear and lasting stirring should be avoided to keep stable thickening ability.
