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.SpecificationAppearance: White fluffy powder Oder: Slightly acetic CAS No.: 9003-01-4 ParameterSolutionValueViscosity/mPa.s(20 rpm at 25 oC, Neutralized Solution)0.2% Water solution19,000-30,0000.5% Water solution40,000-55,000Clarity /% (Neutralized Solutioin 420 nm wavelength)0.2% Water solution≥950.5% Water solution≥95Residual benzene /%-≤0.5Residual acrylic acid/%-≤0.25Loss on drying/%-≤2.0Bulk Density/(g/100 mL)-21.0-27.0Heavy metal Pb+As+Hg+Sb /ppm-≤10Features and Benefits Short flow properties High viscosity High clarityRecommended Applications Hair styling gels Hydroalcoholic gels Moisturizing gels Bath gels Hand, body and face lotions CreamsFormula 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.Standard Packing: 20kg cardboard box with PE lining Storage: Keep tightly closed in cool, dry and well-ventilated area Shelf Life: 24 months
