SPF Value

The formula includes Titanium Dioxide Nano EasyDisperse™.

Based on the product information, this specific grade of Titanium Dioxide is primarily intended for use in makeup products to provide effects like brightening or coverage. It is generally not the grade used or tested for providing reliable UV protection in sunscreen formulations.

Therefore, based on the ingredients provided in this formula, it is unlikely to have a significant or measurable SPF value suitable for effective sun protection. Achieving reliable SPF requires using specific sunscreen-grade UV filters at appropriate concentrations and typically requires in-vivo testing to determine the actual SPF rating.
