Achieving SPF PA+++ with Titanium Dioxide 15nm Liquid (Gloss)

To achieve SPF PA+++ protection in your formulation, it is recommended to use Titanium Dioxide 15nm Liquid (Gloss) in combination with Zinc Oxide 35nm Liquid. These two ingredients work together to provide broad-spectrum protection against both UVA and UVB rays.

• Titanium Dioxide 15nm Liquid (Gloss) primarily protects against short-wave UVA and both short- and long-wave UVB.
• Zinc Oxide 35nm Liquid provides good protection against long-wave UVA.

Using them together ensures comprehensive coverage across the full UVA/UVB spectrum.

The exact percentage needed to reach SPF PA+++ depends on the overall formulation. However, based on product testing, an example formulation using:

• 25% Titanium Dioxide 15nm Liquid (Gloss)
• 15% Zinc Oxide 35nm Liquid

achieved an SPF of 51.06 and PA++.

While this example achieved PA++, increasing the concentration or optimizing the formulation further may be needed to reach PA+++. It is important to note that achieving specific SPF and PA ratings requires testing of the final product.

For a starting point to achieve high protection, consider using a combination of Titanium Dioxide 15nm Liquid (Gloss) and Zinc Oxide 35nm Liquid at percentages similar to the example provided, and then adjust based on your desired SPF/PA level and formulation characteristics.
