Zinc Oxide USP is mainly used in food industry as a dietary ingredient and as a nutrient. Zinc is an important antioxidant nutrient. It is necessary for protein synthesis, wound healing, for blood stability, normal tissue function, and aids in the digestion and metabolism of phosphorus. It also governs the contractility of muscles and maintains the body's alkaline balance. Zinc Oxide is also used in a variety of products like plastics, ceramics, glass, cement, rubbers, paints, pigments, lubricants, adhesives, sealants, batteries, ferrites, flame-retardant, and bandages. It is commonly used in personal care products like baby powders, diaper rash creams, calamine creams, antiseptic ointments, and anti-dandruff shampoos and sunscreens. It is used as an additive in the production of concrete, and as an additive in food products (breakfast cereals).USP, or United States Pharmacopeia, grade chemicals comply with the standards of the United States Pharmacopeia and National Formulary (USP-NF). USP Grade chemicals are fit for use in food, drugs, and medicines. They are subject to stringent testing and are typically required to have the highest level of purity.

Molybdenum,when added to chromium-Nickle austentic steels,improves resistance to pitting Corrosion especially by chorides and sulphur chemicals, when added to low alloy steels, Molybdenum improves high temperature strength and hot hardness. When added to chromium steels it greatly diminishes the tendency of steels to Embrittle in service orin heat treatment. Also see pitting Resistance equivalent.
