Compatibility
Works well with:
Homosalate Octocrylene Ethylhexyl Methoxycinnamate Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine Butyl Methoxydibenzoylmethane
DHHB is an oil-soluble UVA filter with good compatibility across most sunscreen actives and emollient systems. It is known to photostabilize Butyl Methoxydibenzoylmethane (avobenzone), making it a valued pairing in broad-spectrum formulations. No widely documented incompatibilities with common cosmetic co-ingredients, though it should be evaluated empirically in each system.
Formulation notes
Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB) is an oil-soluble organic UVA filter with peak absorption around 354 nm, providing strong broad-spectrum UVA I protection. It is approved in the EU at up to 10% and is valued for its photostability and ability to stabilize other UV filters such as avobenzone. It is not currently approved as a sunscreen active by the US FDA but may be used in US cosmetic formulations outside of OTC drug claims.
