Carbo resin is a series of cross-linked acrylic polymer products. It is a family of water-soluble thickening resins. There are six main models: 940 934 941 2020 u20 u21 #
Carbo resin can be used as an excellent suspending agent, stabilizer, emulsifier, and can also be used as a transparent base of high-end cosmetics and a base for pharmaceutical accessories. Carbo
resin is also the most effective water-soluble thickener. Suggested dosage: The general dosage is 0.2 to 1.0%, in most cases 0.2 to 0.5%. This product\'s 0.2 ～ 2.0% dosage is used as emulsifier,
0.2 ～ 2.0% dosage is used as thickener, 0.2 ～ 2.0% dosage is used as ointment, 0.2 ～ 2.0% dosage is used as gelling agent.
Packaging and storage:
Packaging: This product is packed in non-toxic polypropylene and nylon co-extruded plastic bags, moisture-proof and air-proof, and then packed in a cardboard box, 22kg / carton. Carbomer is very
hygroscopic. When storing, be sure to seal it. Be careful to prevent moisture and agglomeration in the exposed air. If there is a slight agglomeration, gently tap the pressure, it can become a
loose powder, and it will not affect the thickening effect. In a sealed container filled with desiccant. Transport: Carbomer is a polyelectrolyte. Rubbing or squeezing resin particles can
sometimes become static. In case of splashing, please sweep up the dry powder with a broom first, and do not rinse with water, otherwise a very thin layer will form on the ground or equipment.
