Diethylamino Hydroxybenzoyl Hexyl Benzoate (also known as DHHB or Uvinul A Plus) is an oil-soluble organic sunscreen agent that provides strong, photostable absorption in the long-wave UVA range (around 354 nm). It is widely used in sunscreens and daily UV-protective skincare to help prevent UVA-induced photodamage.

| Allergic contact dermatitis | Very rare | Isolated case reports; considered low-sensitizing compared with some older UV filters. |
| Photoallergic reaction | Very rare | Uncommon given its high photostability; rarely documented. |
