Product Description

 

 

 

Pure zinc oxide powder is a high-purity, fine white inorganic powder widely used across industrial, cosmetic and technical applications. It is chemically stable, non-volatile and offers strong whitening, UV-absorbing and protective performance. This product is suitable for formulations that require consistent dispersion, reliable opacity and stable performance in powders, creams, coatings, rubber compounds and ceramic systems. Produced under controlled processing conditions, it helps support uniform quality and predictable application results. The powder is designed for professional use in manufacturing, R&D and formulation work, where purity, particle consistency and functional stability are important. It can be supplied for industrial, cosmetic, pharmaceutical intermediate and laboratory purposes, depending on grade and specification requirements.

Functions and Effects

 

 

 

 

Pure zinc oxide powder provides strong UV absorption, helping to reduce the impact of ultraviolet exposure in coatings and topical formulations. It acts as a white pigment and opacity enhancer, improving brightness and coverage without relying on organic dyes. Its mild astringent and protective properties make it useful in skin-care and personal-care systems where surface protection and formulation stability are needed. In rubber and polymer applications, it supports vulcanization, heat resistance and mechanical reinforcement. The powder also contributes to antimicrobial stability, moisture resistance and long-term durability in finished products. Its chemical inertness and thermal stability help maintain performance under processing and storage conditions.

Application Fields

 

Pure zinc oxide powder is widely applied in cosmetics, sun-care products, baby powders, creams and skin-protective formulations. It is used in rubber manufacturing to improve vulcanization efficiency, wear resistance and product durability. In coatings, paints and adhesives, it enhances whiteness, anti-corrosion performance and film stability. The powder is also suitable for ceramics, glass, pharmaceutical intermediates, feed additives and technical laboratory materials. In personal-care and daily-use products, it helps provide a smooth texture, mild surface protection and consistent visual appearance. For industrial buyers, it can be used in masterbatch production, pigment preparation, polymer modification and specialized functional material development.

FAQ

 

 

Q1:What is the difference between industrial grade and cosmetic grade zinc oxide?
A1:The main difference lies in purity and heavy metal limits. Cosmetic grade typically requires higher purity (≥99.5%) and stricter control over lead and arsenic content to ensure safety for skin contact. Industrial grade is suitable for rubber, ceramics, and coatings where skin safety is not the primary concern.
Q2:Is this zinc oxide powder nano-sized?
A2:Standard pure zinc oxide powder usually has a particle size (D50) around 0.2–0.5 μm, which is considered non-nano. Nano zinc oxide (particle size <100nm) is transparent when applied to skin but requires specific safety labeling. Our standard product provides excellent whitening and opacity.
Q3:Can this product be used in sunscreen formulations?
A3:Yes, zinc oxide is a widely recognized physical UV filter. However, for sunscreen products, you must ensure the specific batch meets the regulatory requirements of your target market (e.g., FDA or EU Cosmetics Regulation) regarding particle size and coating. Please request our specific "Sunscreen Grade" TDS if needed.
Q4:How should I store zinc oxide powder?
A4:Store in a cool, dry, and well-ventilated area. Keep the container tightly closed when not in use to prevent moisture absorption and contamination. Avoid contact with strong acids and aluminum powder, as zinc oxide can react with them.
Q5:What is the shelf life of the product?
A5:Under proper storage conditions, the typical shelf life is 24 months from the date of manufacture. It is recommended to retest the product after this period to ensure it still meets specifications before use.
