Product Description

Carbo resin is a series of crosslinked acrylic polymer products, is a family of water-soluble thickening resins.

Carbo resin can be used as an excellent suspension agent, stabilizer, emulsifier, and also as a transparent substrate for high-grade cosmetics.

Direct method:
1. Sieve the carbomer slowly into the rapidly stirring water to fully disperse it;
2. Stir continuously and pour the water phase into the oil phase;
3. Neutralization with a suitable base (in some cases, neutralization is best done after step 4);
4, rapid mixing to reduce the size of particles, can obtain glossy products. The homogenization method can be used, but high speed shearing will make the emulsion unstable.
Indirect method:
1. Disperse the polymer emulsifier in the oil phase and stir continuously until a smooth and uniform dispersion is formed;
2. Add an appropriate amount of alkali as a neutralizer to the water;
3. In strong agitation, add the oil phase (containing polymer) to the water phase and continue to stir until a white emulsion is formed.
