Diethylamino hydroxybenzoyl hexyl benzoate/DHHB with Cas 302776-68-7
What is Diethylamino hydroxybenzoyl hexyl benzoate ?
Diethylamino hydroxybenzoyl hexyl benzoate,DHHB is a benzoate UV absorber that can effectively absorb 320-400 nanometers of UV light, with a peak absorption of 354 nanometers. It has the characteristics of high UV absorption efficiency and good photothermal chemical stability, and is one of the UV absorbers with the highest absorption efficiency in the UVA band.
DHHB can beuased for cosmetics, sunscreen, filters, etc. It is also very suitable for long-lasting sun protection and facial anti-aging products. The core sun protection principle of diethylaminohydroxybenzoic acid hexyl ester (DHHB) is efficient absorption and light energy conversion.The general dosage is 0.2-0.5%.

Diethylamino hydroxybenzoyl hexyl benzoate/DHHB Applications
DHHB is a typical chemical sunscreen (organic UV absorber). Its core function is not to protect the skin by reflecting ultraviolet rays like physical sunscreens such as titanium dioxide and zinc oxide, but to work through a mechanism of “absorption and conversion”:
Selective absorption of UVA: The molecular structure of DHHB determines its strong affinity for specific wavelengths of light. It can efficiently absorb ultraviolet rays in the 320-400 nanometer wavelength range (especially UVA, which has strong penetration and is prone to skin photoaging), with an absorption peak at around 354 nanometers.
Conversion of light energy into heat energy: When DHHB molecules absorb high-energy ultraviolet photons, they will be excited to an unstable high-energy state. Subsequently, it will release energy through harmless means (mainly converting light energy into trace amounts of heat energy) and quickly return to its original low-energy stable state.
Excellent photostability: Many traditional chemical sunscreens are prone to self decomposition and failure after absorbing ultraviolet light, but DHHB has extremely strong photothermal chemical stability. This means that under prolonged exposure to sunlight, it can repeatedly undergo a cycle of absorption conversion release without easily degrading, providing long-lasting and stable UVA protection for the skin.
