Long flow Carbomer 981/NM-Carbomer 981
INCI
Name: Carbomer
Carbomer 981 is a
cross-linked polyacrylate polymer,long flow carbomer. It
performs the same as NM-Carbomer 941. But it is polymerized in co-solvent
system of ethyl acetate and cyclohexane .
Features and Benefits
Outstanding long flow property
-
Highly efficient at moderate
and low concentration.
-
High clarity
Recommended Applications
Topical lotions, creams and
gels
-
Clear gels
-
Moderately ionic systems
Formula Guidelines
-
Typical recommended dosage at 0.2~1.5%.
-
To disperse NM-Carbomer941
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.
-
The ideal viscosity can be
achieved at ph ranges of 5.0~10.0; To achieve maximum
thickening, NM-Carbomer941 should be 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.
