With the improvement of people's living standards and the intensification of international competition, the research and development of safe and efficient sunscreen cosmetics will gradually increase. Today, the sunscreen cosmetics market in developed countries has shown strong vitality. From 1999 to 2000, the United States' annual sales reached 737 and 765 million U.S. dollars, and the United Kingdom reached 2.45 and 270 million U.S. dollars. In recent years, they have increased at a rate of 20% and 10% respectively. Among them, the consumption of nano-titanium dioxide is also increasing year by year Increased. The annual demand of nano-titanium dioxide in anti-ultraviolet cosmetics in Japan is more than 1000t, and the amount in textiles, plastics, and rubber products is even greater.
From the development trend of sunscreen cosmetics, one is inorganic sunscreens instead of organic sunscreens, and the other is bionic sunscreens. The latter has a higher cost and is difficult to promote now. The former is moderately priced and has superior sun protection performance, so it is generally optimistic. Especially nano-titanium dioxide, because of its superior performance and application prospects, its development momentum and market potential are better.
