We are glad to propose 500 MT of stain less steel mill scale. Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products. At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel. The recovery ratio after melting in furnace for the most valuable alloy elements is: - Ni: 3.5 - 4.5% - Cr: 6-8% From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows: Waste code: 10 02 10 The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers. Chemical analysis of the material is available on request.

Sealed, stored in dark, with a shelf life of 2 years. Reference dosage: The hygiene standards for cosmetics stipulate that the maximum amount added shall not exceed 5%, and the general dosage is 1-4%. 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.
