Yes, zinc oxide and titanium dioxide are physical sun blockers.
Avobenzone is what is problematic for sunscreen and makeup usage.
Avobenzone is said to become unstable when combined with uncoated zinc oxide, uncoated titanium dioxide, and iron oxides of yellow and black. If the zinc oxide, titanium dioxide, and iron oxides are coated or encapsulated, then there is no risk of avobenzone becoming unstable.
I don't see avobenzone in the ingredients list you posted, so there is no problem. Mineral makeup does not become unstable with Ethylhexyl Methoxycinnamate, or OMC, only with avobenzone. |
