Question

Regarding two sunscreen formulations containing Zinc Oxide that have separated and clumped due to insufficient mixing power, should these formulas be discarded?

Answer

Based on the staff's explanation, the separation and clumping in your sunscreen formulations are due to insufficient mixing power, which prevents the ingredients, especially the sunscreen filters like Zinc Oxide, from being properly dispersed or emulsified.

The staff mentioned that if the sunscreen ingredients are not fully dispersed or dissolved, the sun protection efficacy will be compromised or may not be present at all.

Therefore, for your safety and to ensure effective sun protection, it is recommended not to use these separated formulations as sunscreens. While it's unfortunate, the best course of action is to discard them and attempt making new batches with a more powerful mixer as recommended by the staff.
