2020-09-18

Zinc oxide has a weak astringent and antibacterial effect. It reacts with free fatty acids in oils to produce zinc oleate and zinc stearate, which protect the skin.

Zinc oxide Applications in pharmaceuticals, basic physicochemical properties of zinc oxide: Color white powder; Odor: odorless, tasteless, no sand; Structure: hexagonal crystal; Melting point: 1975℃; Boiling point: 2360℃; Flash point: 1436℃; Density: 5.606g·cm-31436℃; Band gap: Solubility: Soluble in acids, concentrated hydroxides, ammonia and ammonium solutions, insoluble in water and ethanol; The covering power is half that of titanium dioxide and zinc sulfide; The coloring power is twice that of basic lead carbonate.

Zinc oxide It has a weak astringent and antibacterial effect, and produces zinc oleate and zinc oleate with free fatty acids in oil, which has a protective effect on the skin. It is absorbed by cells through hair follicles, promotes the synthesis of nucleic acids and nucleoproteins, participates in cell energy metabolism, and plays a role in promoting tissue repair.

Zinc oxide is used to prepare dental or smear pastes. Used in dental adhesives and zinc oxide ointment. Zinc oxide can be used for re-bonding powders. Zinc phosphate cement is developed by mixing powder mainly composed of zinc oxide products and liquid mainly composed of phosphoric acid. It has bonding force, but its strength is insufficient, and it can be dissolved in some saliva, so it is not suitable for direct use as a filling agent. It is used as a base when filling silver amalgam and is used to study the filling of deciduous teeth. Polycarboxylate cement has higher strength, stronger bonding force, and lower solubility than zinc phosphate cement, and its uses are the same as zinc phosphate cement.

Skin disease medication zinc oxide zinc oxide ointment. For eczema, prickly heat and mild, small areas of skin ulcers. Weak astringent, moisturizing, protective effect on the skin, but also adsorption and drying function. Zinc oxide ointment is mixed with petrolatum ointment and zinc oxide. Zinc oxide It has many applications in medicine and has greatly promoted the development of the pharmaceutical industry and promoted production.
