Carbomer 940 HC is a cross-linked polyacrylate polymer. HC means very High Clarity. It is used as a high-efficient rheology modifier, capable of providing high viscosity, excellent clarity. When neutralized by alkali it forms sparkling clear water or hydroalcoholic gels and creams.
Features and Benefits
l Short flow properties
l High viscosity
l High clarity
l Hair styling gels
l Hydroalcoholic gels
l Moisturizing gels
l Bath gels
l Hand, body and face lotions
l Typical recommended dosage at 0.2~1.0 wt %.
l To disperse Carbomer 940 HC 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.
l The ideal viscosity can be achieved at pH ranges of 5.0~10.0 when neutralized; In a hydroalcoholic system, a correct neutralizer must be chosen carefully based on the amount of alcohol to be gelled.
l After neutralization, high-shear and lasting stirring should be avoided to keep stable thickening ability.
