Impacted by air pollution, the ozone layer is thinning and the amount of ultraviolet radiation reaching the surface gradually increases, and the shortwave of UV light trend is enhanced. Especially the medium and long wavelength UV Light(290-400nm) has caused great harm to human health, which lead to skin tanning, pigmentation, keratin growth and aging. What’s more, it even cause skin cancer and immune suppression of the body. Adding sunscreen has become one of the most effective way to against the harm caused by sun radiation.
In recent years, the demand for sunscreen cosmetics is growing, subsequently, new ultraviolet absorbers with high efficiency, high safety and broad spectrum sun protection function are constantly being developed. Among them, benzophenone UV absorber which is developing towards environmental protection and high efficiency is an indispensable variety, such like our OMNISTAB UV BP6.
The benzophenone UV absorber has a relatively wide absorption wavelength, it has a strong absorption in almost all the ultraviolet light region. This bases on its structure the intramolecular hydrogen bonding, the intramolecular hydrogen bond formed between the hydroxyl hydrogen and the carbonyl oxygen on the benzene ring, then an intramolecular chelating ring is formed. When the UV absorber absorbs the ultraviolet energy, the molecules thermal vibrate and the hydrogen bonds break and the chelating ring open, so that transform the harmful ultraviolet energy into harmless heat and release it. In addition, after benzophenone UV absorbers absorb ultraviolet light, it is tautomerized to form an enol structure, which is also a way to dissipate energy.
The Specifications of OMNISTAB UVBP6
Omnistab UVBP-6 can absorb UV light at 320-400nm,but hardly absorb visible light, superior to BP-3(UV-9) for light and heat stability, and it’s widely used in high-quality cosmetics.
UV BP-6 also can be used for light colored or transparent products, with high absorption efficience,non-toxic,no teratogenic side effects. It’s also widely used in polyester, PVC, epoxy resin materials, as well as paint and varnish coatings.
In addition to OMNISTAB UV BP6, we also have a series of UV absorbents that can be used in different cosmetic systems as follows:
