Diethylamino hydroxybenzoyl hexyl benzoate (INCI) is an organic compound used in sunscreens to absorb UVA radiation. It is marketed as Uvinul A Plus by BASF. DHHB has an absorption maximum of 354 nm.[1][2]

DHHB has excellent photostability and compatibility with other UV absorbers and other cosmetic ingredients.[3]

DHHB has been approved for the use in sunscreens in the European Union since 2005 with a maximum of 10 per cent[4][5] and is also approved in South America, Mexico, Japan and Taiwan.[6] In the United States it can be used for product protection.[7]
