Thickener

PRODUCT NAME：Carbomer 940HC

Carbomer 940HCis a cross-linked polyacrylate polymer. HC means very High Clarity. It is usedas a high-efficient rheology modifier, capable of providing high viscosity,excellent clarity. When neutralized by alkali it forms sparkling clear water orhydroalcoholic gels and creams.

    Formula Guidelines  

  • Typical recommended dosage at 0.2-1.0 wt %. 

  • To disperse Carbomer 940HC 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.
