Generated: 2026-09-16T18:20Z - **INCI name:** Diethylamino Hydroxybenzoyl Hexyl Benzoate - **Common name:** Uvinul A Plus (DHHB) - **Typical use range:** Up to 10% (EU Annex VI) - **Evidence tier:** literature-backed - **Functions:** uv-filter ## What it does Diethylamino hydroxybenzoyl hexyl benzoate, known by the trade name Uvinul A Plus, is an organic UV filter that absorbs long-wave UVA, with peak absorption around 354 nm. UVA is the part of the spectrum most associated with the appearance of photoageing and uneven tone, and it reaches skin through cloud and glass, so a strong UVA filter is central to a modern sunscreen. Two properties set it apart from older UVA filters. It is photostable, meaning it does not break down and lose efficacy in sunlight the way unstabilised avobenzone does. And it is oil-soluble with good compatibility with other filters, which lets formulators build a high-UVA sunscreen with a light, non-greasy texture and no white cast. It is listed in Annex VI of the EU Cosmetics Regulation with a maximum concentration of 10%, and is widely used in Europe and Asia. Filters of this generation are the reason today's sunscreens can reach PA++++ ratings while feeling like a light lotion. ## Notes Diethylamino hydroxybenzoyl hexyl benzoate, known by the trade name Uvinul A Plus, is an organic UV filter that absorbs long-wave UVA, with peak absorption around 354 nm.
