Application field 

UV Filter DHHB' s 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
UV Filter 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, UV Filter DHHB has the same effect as the current best sunscreen Avobenzone. However, UV Filter DHHB's 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 UV Filter DHHB.
UV Filter DHHB instead of Avobenzone, become a model UVA sunscreen agent, with better light stability than Avobenzone, do not need to add MBC, OMC compound, lower cost, better effect.
