Its solid products are in the form of white powder, with a chemical purity of 98--99%.
1.Usage:
Poly(ethylene oxide) resins are high molecular weight homoploymers produced by the heterogeneous catalytic polymerisation of ethylene oxide.The resins are characterised by the structural formula:hoch2ch2o(ch2ch2o)nh.Poly(ethylene oxide) is water soluble resins.Aqueous solutions with low concentrations are very tacky and sticky. Poly(ethylene oxide) can used as long fibre dispersing agent in manufacture of paper, adhesives, friction reduction agent, flocculating agents, thickecing agents and lubricants and so on.

Usage:
Sunscreen agent-1789 is the most effective fat soluble UVA filter and is a safe and effective UVA sunscreen approved by the US FDA for sale on the counter. It can effectively block UVA, thereby increasing the SPF value of sunscreen products. It can improve the efficacy of sunscreen products when used in combination with UVB filters, and BL-200 has the best effect when used in combination with octyl methoxycinnamate. BL-200 can increase its stability in the product. It has an extremely effective protective and repairing effect on human skin.
Application:
This product is soluble in oil and can be formulated into a cream using the usual method. However, the product turns red when it encounters metal ions, so other components such as formula water should not introduce metal ions. The equipment should be made of pure stainless steel, and an appropriate amount of EDTA-2Na should be added to the formula water phase to chelate with metal ions.

Product feature
Calcium chloride is an inorganic salt, which exists as solid or liquid. Solid calcium chloride is a white, crystal substance in the form of flake, granule, pellet or powder. With different crystallized water contents, it can be dihydrate or anhydrous.
Liquid calcium chloride is a colorless, clear solution. As calcium chloride has such properties as quick dissolving, exothermic ability, attracting moisture from the air and surroundings, dissolving at very low temperature,
