What is the SPF value provided by 1% concentration of Zinc Oxide 200nm EasyDisperse™ in an oil-based cream formulation?

Answer

SPF Value per 1% of Zinc Oxide 200nm EasyDisperse™

Regarding the SPF value per 1% concentration of Zinc Oxide 200nm EasyDisperse™ in a formulation, the product description does not provide a specific SPF value per 1% for this particular type of Zinc Oxide. The effectiveness can vary depending on the overall formulation, especially in an oil-based system.

The recommended usage rate for Zinc Oxide 200nm EasyDisperse™ is typically between 5% and 25% to achieve desired sun protection efficiency. For accurate SPF calculation, it is generally necessary to perform in-vivo testing on the final product formulation.

Therefore, a simple calculation of SPF per 1% is not applicable or provided for this specific ingredient.
