What it does
Contributes UVA protection within a tested formula. It does not by itself provide complete UVB protection or establish a product's SPF.
Sources: 1, 2, 3Good for
- UVA protection in tested sunscreens
How to use it
Apply and reapply the finished sunscreen according to its label. Protection depends on sufficient application and other sun-protection measures.
Sources: 1, 2, 3Who should be careful
Select a suitable finished sunscreen and follow its label. Ingredient authorization and impurity specifications depend on the market; eye stinging or formula reactions are still possible.

Usage, safety and formulation details
Mechanism of action
Its molecular chromophore absorbs UVA radiation. Film formation, concentration and the other filters influence the finished sunscreen's performance.
Sources: 1, 2, 3Potential adverse effects
Some users experience irritation, contact allergy or eye stinging; select a tolerated finished sunscreen rather than abandoning sun protection.
Sources: 1, 2, 3Formulation considerations
Verify the trade grade, solubility, supplier purity specification and current DHHB impurity advice, including DnHexP. Do not infer an actual product's impurity content from the INCI alone.
