  • How to convert ZnO to Zn?

    The assay counts the oxide % ZnO. This is not comparable to Zn informed with Zn content. Thus the molecule calculation is as follows: ZnO Atoms Zn mol mass. Zn 1 65,38 65,38 80,34 % conversion factor. O 1 16,00 16,00. Total mass 81,38. 40 ZnO 80,34 % = 32,14 Zn. Meaning that 40% ZnO without Oxide converts to 32.14% Zn.

  • Sunscreen Percentage Concentration Matters

    Zinc Oxide: 5% minimum; 10-20% is ideal. It is more common to see 2-7% concentrations. 25% is the legal maximum. Anything at this level in a cream form will be very thick and uncomfortable for daily wear on the face. Unless you are extremely photosensitive, this level would be more appropriate for intense sunshine, e.g. trekking in the desert, skiing, or hiking at high altitude.
