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 concentration of 10%[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]
