Carbomer 981 is a cross-linked polyacrylate polymer. It performs the same as Carbomer 941. but it is polymerized in co-solvent system of ethyl acetate and cyclohexane..
Features and Benefits
l Outstanding long flow property
l Highly efficient at moderate and low concentration.
l High clarity
l Topical lotions, creams and gels
l Clear gels
l Moderately ionic systems
l Typical recommended dosage at 0.2~1.5%.
l To disperse Carbomer 981 completely, it should be slowly and carefully sifted 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; To achieve maximum thickening, Carbomer941 should be neutralized; in a hydoalcoholic 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.
