carbomer 940

Product Description

GM-CARBOMER 940
MF: C3H4O2
CAS No.: 9007-20-9
EINECS No.: 202-415-4
Features and Benefits  
Short flow properties / High viscosity / High suspending, thickening and stabilizing ability/ High clarity
Recommended Usage
Hair styling gels / Hydroalcoholic gels/ Moisturizing gels/Bath gels/ Hand, body and face lotions/Creams
Formula suggested
1. Typical recommended dosage at 0.2-1.0 wt %.
2. To disperse GM-Carbomer940 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; 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.
