Application of titanium dioxide in cosmetics

wallpapers Industry 2020-07-21
Because ultraviolet rays are very harmful to the human body, developed countries have paid more attention to the research and development of sunscreen products in recent years. They have successfully introduced a variety of anti-ultraviolet fibers, plastics, films, coatings, sunscreen creams, foundations, and lipsticks. Sunscreen cosmetics such as mousse and ointment. In recent years, my country has also increased the research and production of sunscreen cosmetics.

However, in the past, sunscreens were mostly organic compounds such as benzophenones, anthraquinones, salicylates, para-aminobenzoic acids, and cinnamates, which were unstable, short-lived, and had more significant side effects. Has a certain degree of toxicity and irritation. If it is added in excess, it will cause chemical allergies and may even cause skin cancer. Nano-titanium dioxide is an inorganic component with excellent chemical stability, thermal stability and non-migration, durable decoloring power, hiding power, low corrosiveness, superior dispersibility, and non-toxic, odorless, It is non-irritating, safe to use, and has the function of sterilization and deodorization. More importantly, as mentioned above, nano-titanium dioxide can absorb ultraviolet rays and emit and scatter ultraviolet rays, so it has a robust anti-ultraviolet ability. Compared with the same dose of organic anti-ultraviolet agent, its absorption peak in the ultraviolet region Higher; and nano-titanium dioxide has a blocking effect on the ultraviolet in the medium wave region and the longwave region, unlike the organic anti-ultraviolet agent, which only shields the ultraviolet light in the medium wave region or the longwave region. This is mainly due to its finer particles, high transparency of the finished product, visible light transmission, natural skin whiteness when added to cosmetics, overcoming the opacity of some organic matter, or pigment-grade titanium dioxide the skin unnaturally pale. Because of this, nano-titanium dioxide quickly received widespread attention and gradually replaced some biological anti-ultraviolet agents, becoming a physical shielding anti-ultraviolet agent with superior performance in today's sunscreen cosmetics.

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 relatively high cost and is difficult to promote now. The former is generally optimistic because of its moderate price and superior sun protection performance. Especially nano-titanium dioxide, due to its excellent performance and application prospects, its development momentum and market potential are better.

Trunnano is one of the largest titanium dioxide producers in the world. There are titanium dioxide powders and photocatalyst products in various particle sizes. If necessary, please contact Dr. Leo. Email: brad@ihpa.net.
