The primary use of Ammonium Sulphate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of Ammonium Sulphate is its low nitrogen content relative to Ammonium Nitrate, which elevates transportation costs.
It is also used as an agricultural spray adjuvant for water soluble insecticides, herbicides, and fungicides. There it functions to bind iron and calcium cations that are present in both well water and plant cells. It is particularly effective as an adjuvant for 2,4-D (amine), glyphosate and glufosinate herbicides.

Packaging and storage: 1kg/aluminum foil bag. 25kg/barrel, pharmaceutical packaging barrel. 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.
