Diethylamino Hydroxybenzoyl Hexyl Benzoate

Diethylamino Hydroxybenzoyl Hexyl Benzoate (Uvinul A Plus) is an oil-soluble UVA filter typically used around ~1–10% in sunscreens and is generally well tolerated in repeat insult patch testing, with low rates of irritation and sensitization compared with many other UV filters. In sensitive or eczematous skin, stinging is still possible—often influenced by the overall sunscreen vehicle and cumulative exposure—so it is not fully inert, but its intrinsic irritancy potential is low. Safety Notes: Diethylamino Hydroxybenzoyl Hexyl Benzoate (Uvinul A Plus) is a UVA filter used primarily in leave-on sunscreens and daily moisturizers with SPF; at the low end it appears in multi-filter facial SPFs and tinted products around ~0.2–1% where UVA coverage is shared with other filters. High-strength consumer sunscreens, especially EU/Asia-style high-UVA protection formulas, commonly use ~5% and can reach ~10% in OTC products, aligning with EU allowance up to 10% for this filter; it is uncommon in rinse-off products.
