It is capable of providing high viscosity, excellent thickening and suspending performance with low-dosage. Its short flow (non-drip) properties are ideal for applications such as clear gels, hydroalcoholic gels, creams. When neutralized by alkali it forms sparkling clear water or hydroalcoholic gels and creams. Features and Benefits ⚫     Short flow properties ⚫     High viscosity ⚫     High suspending, thickening and stabilizing ability ⚫     High clarity Recommended Applications ⚫     Hair styling gels ⚫     Hydroalcoholic gels ⚫     Moisturizing gels ⚫     Bath gels ⚫     Hand, body and face lotions ⚫     Creams Formula Guidelines ⚫ Typical recommended dosage at 0.2~1.0 wt %. ⚫ To disperse Carbomer 940 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
