There are significant differences between USP grade magnesium oxide and ordinary magnesium oxide in terms of purity, production process, usage and safety standards. Therefore, when choosing magnesium oxide products, you need to choose the appropriate level and type according to the specific application scenarios and needs.
I, Purity
USP grade magnesium oxide: as the United States Pharmacopeia standards of magnesium oxide, its purity requirements are extremely high, usually required to reach the level of medicinal use, to ensure that no harmful impurities and pollutants.
Ordinary magnesium oxide: Its purity is relatively low and contains a certain amount of impurities which may be limited or affected in certain applications.
2, the production process
USP grade magnesium oxide: its production process is relatively complex, requiring strict control of reaction time, pressure, temperature and other conditions to ensure the purity and quality of the product. At the same time, the by-products produced also need to be properly handled to reduce the impact on the environment.
Ordinary magnesium oxide: the production process is relatively simple, the control of reaction conditions is not as strict as USP grade, and in some cases may not be environmentally friendly treatment of by-products.
3, usage
USP grade magnesium oxide: due to its high purity and good biocompatibility, USP grade magnesium oxide has a wide range of applications in the pharmaceutical field, such as as antacids, laxatives, etc. It is also used in the food industry as a PH regulator, color stabilizer and food additives. In addition, it is also used in high-end fields such as electronic information and new energy.
Ordinary magnesium oxide: more used in the fields which do not require high purity, such as building materials, water treatment, rubber, plastics and other industrial fields.
4, Safety standard
USP grade magnesium oxide: as a pharmaceutical grade product, its safety standards are extremely high, need to comply with the strict quality management standard for pharmaceutical production (GMP) and drug safety requirements.
Ordinary magnesium oxide: although also need to comply with certain safety regulations, but relative to USP grade magnesium oxide, its safety standards may be lower, and in some cases there may be safety risks.
