Most people believe that sunshine is good for health. However, a large number of skin pathological studies have shown that intense solar radiation, especially UVB&UVA (290 - 400 nm), poses a great harm to human health. It can cause skin tanning, pigmentation, skin-aging, and even skin cancer.
Sunscreen became one of the most effective measures to prevent the damage of UV radiation on human health. UV absorber is the crucial component which bring protection effect. It has been used in cosmetics for more than 70 years.
In 1928, the United States reported that benzene salicylate and benzene cinnamate two UV absorbers were first used in emulsion cosmetics. In 1930, sunscreen cosmetics first appeared in the Australian market. Nowadays, the demand of sunscreen cosmetics increases year by year, new uv absorbers with high efficiency, high safety and broad absorption spectrum are constantly developed!
Some hot UV absorbers in sunscreens:
Cinnamic acid derivative
Cinnamic acid uv absorbers have high absorption coefficients due to the conjugated bond formed between benzene ring and carbonyl group. In sunscreen cosmetic market, nearly 70 % product use Cinnamic acid derivative.
