Also known as: DHHB, Uvinul A Plus, Diethylamino Hydroxybenzoyl Hexyl Benzoate
Key Benefits
DHHB (Uvinul A Plus) is a broad-spectrum UVA filter covering the long-wave UVA-I spectrum (320β400 nm, peak ~354 nm). Studies suggest it may provide superior photostability compared to avobenzone, potentially offering more consistent UVA protection throughout sun exposure without degradation.

π Why Regulations Differ
DHHB received EU approval in 2005 (Commission Directive 2005/9/EC) and is approved in Japan and other markets. However, the FDA has not approved it for US sunscreens as of 2025. Like other newer UV filters, it requires demonstration of GRASE status through the FDA's NDA or citizen petition process, which is resource-intensive and has deterred US approval despite a strong EU safety record.
Recent Regulatory Changes
- β’ SCCS reaffirmed safety at 10% in June 2025 for face creams, lotions, and sprays
