Features and Uses

Diethylaminohydroxybenzoyl hexyl benzoate(DHHB) is a broad-band oil-soluble UV absorber, white to off-white crystalline powder. UVA PLUS has a strong absorption of ultraviolet rays in the whole UVA band (320nm-400nm), and only a small amount of addition to the formula can increase the SPF value. It is an effective light stabilizer for avobenzone.
