Product Description

Carbomer 940HC 

Carbomer 940HC 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

1. Short flow properties 
2. High viscosity 
3. High clarity

Recommended Applications 

1. Hair styling gels 
2. Hydroalcoholic gels 
3. Moisturizing gels 
4. Bath gels 
5. Hand, body and face lotions 
6. Creams

Formula Guidelines 

1. Typical recommended dosage at 0.2-1.0 wt %. 
2. 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.
3. The ideal viscosity can be achieved at pH ranges of 5.0~10.0 when neutralized;
4. In a hydoalcoholic system, a correct neutralizer must be chosen carefully based on the amount of alcohol to be gelled. 
5. After neutralization, high-shear and lasting stirring should be avoided to keep stable thickening ability.
