Zinc Oxide Particle Size and Product Sourcing

Regarding your questions:

Zinc Oxide (Micronized) Particle Size: The Zinc Oxide (Micronized) product has a particle size typically ranging from 1 to 10 microns. According to the general definition, particles below 100 nanometers (0.1 micron) are considered nano-sized. Therefore, the Zinc Oxide (Micronized) product, with particles in the micron range, is considered non-nano.

We also offer other types of Zinc Oxide with different particle sizes, including nano-sized options like Zinc Oxide 35nm Liquid and Zinc Oxide (40nm, Triethoxycaprylylsilane Coated), as well as a non-nano option specifically recommended for "non-nano" claims, which is Zinc Oxide 200nm EasyDisperse™.
Product Sourcing and Safety Verification: We understand your concern about product safety. We carefully select our ingredients to ensure they meet quality and safety standards for cosmetic and food applications. However, specific detailed information regarding the source country or supplier for each individual ingredient is proprietary and not typically provided to end-users for verification through this platform. You can be assured that we strive to provide high-quality ingredients for your formulations.
