The Journal of the American Institute for Conservation (JAIC) is an international peer-reviewed periodical for the art conservation profession. The Journal publishes articles on treatment case studies, current issues, materials research, and technical analyses relating to the conservation and preservation of historic and cultural works. The topics encompass a broad range of specialties including architectural materials, archeological objects, books and paper, ethnographic materials, objects, paintings, photographic materials, sculpture, and wooden artifacts. Started as the Bulletin of the International Institute for Conservation-American Group (IIC-AG), in April 1961, the Journal matured into its current form in 1977. Since that time JAIC has become a repository for the core body of conservation information through its documentation of new materials, changing methods, and developing standards in the conservation profession. The four-color publication is distributed three times a year to AIC members and museum, library, and university subscribers.

Although barium sulfate is almost completely inert, zinc sulfide degrades upon exposure to UV light, leading to darkening of the pigment. The severity of this UV reaction is dependent on a combination of two factors; how much zinc sulfide makes up the pigments formulation, and its total accumulated UV exposure. Depending on these factors the pigment itself can vary in shade over time, ranging from pure white all the way to grey or even black. To suppress this effect, a dopant may be used, such as a small amount of cobalt salts, which would be added to the formulation. This process creates cobalt-doped zinc sulfide. The cobalt salts help to stabilize zinc sulfide so it will not have as severe a reaction to UV exposure.

Toxic effects of TiO₂ NPs on aquatic organisms

The major applications studied in the report include paints & coatings, plastics, printing inks, paper & pulps, rubber, leather, linoleum, and others. Region-wise, the market is studied across North America, Europe, Asia-Pacific, and LAMEA. Presently, Asia-Pacific accounts for the largest share of the market, followed by North America and Europe.

Titanium dioxide A1 adopts good oxidation process, composite inorganic coating and organic treatment, and has the characteristics of excellent particle size distribution, high brightness and high weather resistance. It is recommended for high gloss and high weather resistance coatings, inks and outdoor polymer materials.

The EU expert panel did not identify an immediate health concern linked to TiO₂ when used as a food additive. However, due mainly to uncertainties concerning the safety of TiO₂ nanoparticles, the panel concluded that TiO₂ as a food additive (E171) could no longer be considered safe.

The alarming fact of this study is that it was only conducted for 100 days, I have been wearing makeup daily for at least the last fifteen years & would have eaten kilo's of lipstick in my life time - what effects has this had on my system & health??

Reacting to the report, France’s ministers of health, agriculture and economy instructed the country’s food health and safety agency, Anses, to investigate whether the additive poses a risk for human health.

The study was said to be prompted by “growing concerns that daily oral… Intake is associated with an increased risk of chronic intestinal inflammation and carcinogenesis”, or cancer formation”.

Un pigment apparenté, mais où le sulfate de baryum est remplacé par du sulfate de calcium, prend le nom de « sulphopone »

Method of producing improved lithopone

In food, titanium dioxide has a few different uses. Most notably, its food-grade form is used as a colorant to enhance and brighten the color of white foods such as dairy products, candy, frosting, and the powder on donuts. For foods that are sensitive to UV light, titanium dioxide is used for food safety purposes to prevent spoilage and increase the shelf life of food.

Sunscreens made with mineral active ingredients, like titanium dioxide and zinc oxide, generally score well in EWG’s Guide to Sunscreens. They provide strong sun protection with few health concerns and don’t easily break down in the sun.
