Frequently Asked Questions (FAQ)
Q: What's the difference between Uvinul A Plus and Avobenzone?
A: While both are UVA filters, Uvinul A Plus offers superior photostability and doesn't require stabilizers. It's less likely to cause skin irritation and maintains efficacy longer under UV exposure.
Q: Can I use Uvinul A Plus in the United States?
A: Currently, Diethylamino Hydroxybenzoyl Hexyl Benzoate is not FDA-approved for sunscreen use in the US. It's approved in many other regions including Europe and Asia.
Q: What concentration should I use in my formulation?
A: Typical use levels range from 1-5%, with maximum allowed concentrations varying by region (up to 10% in EU). Always verify local regulatory limits.
Q: How does it compare to mineral UVA filters?
A: Unlike zinc oxide (which provides broad-spectrum but weaker UVA protection), Uvinul A Plus offers strong, specific UVA protection with cosmetically elegant formulation properties.
