The FDA is reviewing the safety of titanium dioxide in response to an April petition from EWG and other environmental and public health groups. This is the FDA’s first comprehensive review of titanium dioxide since 1973.

Micronized titanium dioxide doesn’t penetrate skin so there’s no need to be concerned about it getting into your body. Even when titanium dioxide nanoparticles are used, the molecular size of the substance used to coat the nanoparticles is large enough to prevent them from penetrating beyond the uppermost layers of skin. This means you’re getting the sun protection titanium dioxide provides with no risk of it causing harm to skin or your body. The coating process improves application, enhances sun protection, and prevents the titanium dioxide from interacting with other ingredients in the presence of sunlight, thus enhancing its stability. It not only makes this ingredient much more pleasant to use for sunscreen, but also improves efficacy and eliminates safety concerns. Common examples of ingredients used to coat titanium dioxide are alumina, dimethicone, silica, and trimethoxy capryl silane.

It is expected that the implementation of rutile titanium dioxide market manufacturers will be stable this week, the new single quotation of the production link will be firm, the supply of low-cost goods will be reduced, and the reference range of the overall market transaction will rise slightly. It is expected that the market transaction reference is 15200-16200 yuan/ton, and the weekly average price may refer to 15600 yuan/ton. In addition, considering the difference of orders received by different manufacturers, some manufacturers may still have 300-500 yuan/ton of negotiation room. On the demand side, most buyers still have inventory to use, so the current new batch transaction intention is not strong; On the supply side, some producers are expected to increase the load next week, so the industry time output may be slightly increased. On the whole, it is expected that the overall trading range will rise slightly next week, but most producers will adjust the real single negotiation range according to their own orders, and the new single stable price of mainstream producers.

Lithopone B301, Lithopone B311 powder, brilliant white pigment used in paints, inks, leather, paper, linoleum, and face powder. It was developed in the 1870s as a substitute or supplement for lead carbonate (white lead), to overcome its drawbacks of toxicity, poor weathering, and darkening in atmospheres that contain sulfur compounds. Lithopone B301, Lithopone B311 powder is an insoluble mixture of barium sulfate and zinc sulfide that precipitates upon mixing solutions of barium sulfide and zinc sulfate. The precipitate is recovered by filtration, then calcined (roasted) at temperatures above 600° C (1,112° F). Although Lithopone B301, Lithopone B311 powder has been replaced in many applications by titanium dioxide, it is still widely used in a number of products, such as water paints.
