What is Diethylamino Hydroxybenzoyl Hexyl Benzoate/ DHHB?

Diethylamino Hydroxybenzoyl Hexyl Benzoate/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.

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'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 DHHB.

1.DHHB can be used as a photo initiator in UV-curing applications such as inks, imaging, and clear coatings in the printing industry.

2.DHHB Prevents ultraviolet (UV) light from damaging scents and colors in products such as perfumes and soaps.

3.DHHB can also be added to the plastic packaging as a UV blocker. Its use allows manufacturers to package the product in clear glass or plastic. Without it, opaque or dark packaging would be required.
