The high pH soil (pH 7.2) was less susceptible to the effects of zinc exposure. At the highest doses of zinc (2500 mg/kg dw soil), both nano and non-nano particulate zinc applications elicited a similar response in the soil bacterial community, and this differed significantly to the ionic zinc salt treatment.

We’re big on the power of non-nano Zinc Oxide, a natural mineral that helps to provide a physical barrier between the skin and the sun. Non-nano zinc oxide powder is recommended as it doesn't get absorbed into the skin and stays on the surface, providing protection from UV rays. You can adjust the amount of zinc oxide powder to increase or decrease the SPF of the lip balm. Essential oils are optional, but peppermint oil can provide a refreshing sensation on the lips. Zinc Oxide nanoparticles have been synthesized by two simple routes using Aloe vera (green synthesis, route I) or Cassava starch (gelatinization, route II). The XRD patterns and Raman spectra show that both synthesis routes lead to single-phase ZnO. XPS results indicate the presence of zinc atoms with oxidation state Zn2+. SEM images of the ZnO nanoparticles synthesized using Cassava starch “Both nano particle—a smaller particle size—and traditional zinc oxide sunscreens are both safe and effective, and both will be considered safe for reefs. The only difference is the cosmetic feel on the skin.” So you’re pretty much good to go with a mineral-based option. How do I know if a sunscreen is "reef friendly"? Zinc oxide nanoparticles are the specially prepared mineral salt having particle size of 1 to 100 nm. It promotes growth can act as antibacterial agent, modulates the immunity and reproduction of the animals. Both in lower and higher doses of specifications it has exhibited a variety of effects on animal performances. Ingredients: Non-nano zinc oxide (23%), Organic Coconut Oil, Organic Almond Oil, Organic Cocoa Butter, Organic Beeswax, Thanaka Powder, Organic Shea Butter, Organic Cacao Powder, Organic Cinnamon Oil. Why I Love It: A high content of non-nano zinc oxide (23%) High SPF 50; Natural anti-aging formula; Subtle tint adding a tone-up effect bkbEUUt.
