Safety assessment of zinc oxide

 Zinc oxide (ZnO) is a common inorganic compound used in a variety of applications, including the pharmaceutical, cosmetic, electronic, coatings and rubber industries. Its unique physical and chemical properties permit it to show a wide range of applications in these fields. Zinc oxide is a white powder with the chemical formula ZnO, having a density of about 5.61 g/cm³ and a melting point of 1975°C. It is not soluble in water but can be dissolved in water. It is insoluble in water but soluble in acids and bases and has a high refractive index and good covering power. Zinc oxide is a basic oxide that reacts with acids to form the corresponding zinc salts and water and also has some catalytic and photocatalytic activity. In the pharmaceutical and cosmetic fields, zinc oxide is commonly used in the preparation of topical medicines and sunscreens with good antibacterial and anti-inflammatory properties, providing efficient UV protection and whitening effects. In the electronics industry, zinc oxide is used as a transparent conductive film in varistors, photodiodes and liquid crystal displays to improve the performance and reliability of electronic devices. In the coatings and rubber industries, zinc oxide is used as a pigment and filler, providing good coverage and weathering resistance and improving the physical properties and aging resistance of rubber.
Zinc Oxide
 Although zinc oxide shows promise for a wide range of applications in several fields, its potential risks should be noticed. Long-term inhalation of zinc oxide dust may lead to respiratory disorders such as lung inflammation and chronic obstructive pulmonary disease. Zinc oxide nanoparticles, due to their small particle size, can easily enter the respiratory tract and lungs and may lead to more serious health problems. Some people may have an allergic reaction to zinc oxide, which is manifested by symptoms such as redness, swelling and itching of the skin. Highly concentrated solutions of zinc oxide may be irritating to the skin and eyes. Accidental ingestion of large quantities of zinc oxide may lead to indigestion, nausea and vomiting, and prolonged ingestion of excessive zinc oxide may cause damage to the liver and kidneys. In addition, zinc oxide may be toxic to aquatic organisms and plant growth when it enters water bodies and soil, affecting the ecological balance. Therefore, a thorough assessment of the safety of zinc oxide is essential.
  To ensure the safe use of zinc oxide, a comprehensive safety assessment is required. Toxicological assessment assesses the acute toxicity, chronic toxicity and genotoxicity of zinc oxide through animal experiments to understand its short-term and long-term effects on organisms. Environmental impact assessment assesses the effects of zinc oxide on water and soil through experiments to determine its safe concentration in water and soil. Develop occupational health standards for zinc oxide to limit dust concentrations in the workplace and protect worker health. Clearly, mark precautions for use and safety measures on the labels and instructions of zinc oxide products to guide users in their proper use. Set standards for the disposal of zinc oxide waste to ensure its safe disposal and avoid pollution of the environment. In addition, research and develop safer alternatives to zinc oxide to reduce potential risks and conduct a performance evaluation of the alternatives to ensure that they are no less effective than zinc oxide in applications.
 Zinc Oxide
 In summary, zinc oxide, as a multifunctional inorganic compound, exhibits a wide range of applications in many fields, such as pharmaceuticals, cosmetics, electronics, coatings and the rubber industry. However, its potential risks should be addressed, and a comprehensive safety assessment is required to ensure its safety in use. Toxicological evaluation, environmental impact analysis, usage guidelines, and research on alternatives are important measures to ensure the safety of zinc oxide. Relevant companies and consumers should adhere strictly to usage guidelines and implement necessary protective measures to reduce potential risks. In the future, with the development of science and technology and heightened safety awareness, the safe use of zinc oxide will be further ensured and continue to play an important role in a number of fields.
