When sourcing Zinc Oxide (ZnO) powder, it's essential to understand that not all grades are created equal. The purity, particle size, and intended application dictate which grade of zinc oxide is most suitable. NINGBO INNO PHARMCHEM CO.,LTD. offers high-quality zinc oxide powder, emphasizing the importance of choosing the right grade for optimal results in cosmetics, pharmaceuticals, and industrial uses.

The primary grades of zinc oxide encountered in the market are Pharmaceutical Grade, Cosmetic Grade, and Technical Grade. Pharmaceutical grade zinc oxide adheres to the strictest purity standards, ensuring it is free from contaminants and suitable for medical applications, including certain dermatological treatments and high-end sunscreens. Cosmetic grade zinc oxide is specifically formulated for skincare and makeup products. It is tested for safety and efficacy, often featuring a fine particle size that allows for good dispersion and a smooth feel, making it ideal for creating products like foundations, concealers, and daily moisturizers with SPF.

Technical grade zinc oxide, while often more economical, typically has lower purity levels and may contain impurities that make it less suitable for direct skin application. It is generally used in industrial applications such as rubber manufacturing, ceramics, and paints, where high purity is not a critical requirement. For anyone looking to buy zinc oxide for skincare or cosmetic formulations, prioritizing pharmaceutical or cosmetic grade is crucial. The price of zinc oxide often reflects its grade and purity.

When considering zinc oxide powder for your formulations, aspects like particle size (nano vs. non-nano) and whether it's coated or uncoated are also important. Non-nano zinc oxide is preferred for sunscreens as it sits on the skin's surface, providing a physical barrier against UV rays without being absorbed. Uncoated zinc oxide is generally more reactive and can offer better UV protection, while coated versions may offer improved dispersion or texture.
