Diethylamino Hydroxybenzoyl Hexyl Benzoate CAS NO.302776-68-7

 Applications of DHHB: 

DHHB function played in sunscreen products include:

(1) With high absorption effect on UVA

(2) With strong protective effect for free radical produced by UV.

(3) Enhance the SPF value of UVB sunscreen 

(4) With very good light stability, maintain effectiveness for long time

DHHB defilade of UV range covered the whole UVA, from 320 to 400 nm wavelength, the maximum absorption peak is

at 354 nm. So for the shielding, DHHB has the same effect as the current best sunscreen Avobenzone. However, 

DHHB stability in the sun is much better than Avobenzone, because Avobenzone’s ability to absorb ultraviolet radiation

will quickly reduce in the sun. Therefore in the formula you need to add other UV absorber as a light stabilizer, 

in order to reduce the loss of Avobenzone. And it is not necessary to worry about this problem when using DHHB.

DHHB instead of Avobenzone, become a model UVA sunscreen agent, with better light stability than Avobenzone, do not 

need to add Sunsafe-MBC, SUNSAFE - OMC compound, lower cost, better effect.

Solubility: Easily dissolve in ethyl acetate and ethanol, insoluble in water.

Stability and Storage: 

DHHB can be safely handled without any irritation caused to the skin. DHHB should be stored in a closed system, 

and be kept in a dry and dark place without any light exposure.

Package: 25kg net cardboard drum.

Shelf life: 24 months.
