Ethylene glycol diacetate is a versatile intermediate used in the production of various pharmaceutical compounds. Its purity and consistency are vital for the synthesis of high-quality drugs. The presence of impurities in this intermediate can lead to contamination of the final product, posing serious health risks to patients. Therefore, manufacturers must implement stringent quality control measures to ensure the purity of ethylene glycol diacetate.

- Fourth, since the sulfate required for the production of the present invention is provided by the acid leaching slag itself, the mass fraction of the SO/- contained in the acid leaching slag is 15% or more, and the nanometer is prepared by using the acid leaching residue as the zinc and sulfate raw material of the lithopone. Lide powder products not only realize the resource utilization of acid leaching slag, but also turn waste into treasure, and treat and improve the acidic soil of acid leaching residue to purify the environment. Low production costs and simple operation. The metathesis reaction is carried out in a low-density ammonia system (the metathesis reactant is dissolved in recovered ammonia water), and the crystal nucleus formed is smaller. It is non-toxic and safe. The ammonia solution after synthesis and separation is returned to the leaching. There is no waste water in the whole production process. The produced waste residue meets the national solid waste discharge standard for efflux, conforms to the national industrial policy, and is an environmentally friendly “green” type process.

This article discusses the discovery of phosphorescent lithopone on watercolor drawings by American artist John La Farge dated between 1890 and 1905 and the history of lithopone in the pigment industry in the late 19th and early 20th centuries. Despite having many desirable qualities for use in white watercolor or oil paints, the development of lithopone as an artists' pigment was hampered by its tendency to darken in sunlight. Its availability to, and adoption by, artists remain unclear, as colormen's trade catalogs were generally not explicit in describing white pigments as containing lithopone. Further, lithopone may be mistaken for lead white during visual examination and its short-lived phosphorescence can be easily missed by the uninformed observer. Phosphorescent lithopone has been documented on only one other work-to-date: a watercolor by Van Gogh. In addition to the history of lithopone's manufacture, the article details the mechanism for its phosphorescence and its identification aided by Raman spectroscopy and spectrofluorimetry.
Titanium dioxide is an insoluble mineral, meaning it cannot dissolve in water. Known for its bright, white pigment, manufacturers use titanium dioxide in many different capacities, including in cosmetics, foods, and drugs.
When manufacturers add titanium dioxide to foods and other ingestible products, it’s typically referred to as E171, which relates to food-grade purity.
Anatase titanium dioxide is a popular ingredient in coatings due to its excellent UV resistance and chemical stability. Many manufacturers and businesses rely on wholesale suppliers to provide high-quality anatase titanium dioxide for their coating applications.

DUBLIN--(BUSINESS WIRE)--The Lithopone Market by Application: Global Opportunity Analysis and Industry Forecast, 2020-2027 report has been added to ResearchAndMarkets.com's offering.
Titanium dioxide (TiO2) is a naturally occurring mineral that is mined from the earth, processed and refined, and added to a variety of foods, as well as other consumer products. White in color, it is used to enhance the color and sheen of certain foods and is also key for food safety applications. In its natural state it exists in different bulk crystalline forms, such as anatase and rutile, but during processing it is ground into a very fine powder.

It's also worth noting that even prior to the EU decision, France had already outlawed titanium dioxide in food back in January 2020.

Lithopone is an inorganic white pigment, obtained from co-precipitation of Zinc sulfide (ZnS) and Barium sulfate (BaSO4). Titanium Dioxide (TiO2) has replaced Lithopone as a white pigment in majority applications as TiO2 is more durable. However, it is much cheaper than TiO2 and has advantages such as low binder requirement and good dispensability. As a white pigment, it can improve the substrate's weather resistance, and improve the fungicidal properties of paint formulations. Some of the major applications of Lithopone include manufacturing of paint pigments, plastic & rubber products, paper, printing inks, cosmetics, and leather & linoleum products. It is commercially available under names such as pigment white 5, Barium zinc sulfate sulfide, Becton White, C.I. 77115, Charlton White, Enamel White, and Zincolith. On the basis of content of ZnS, Lithopone is available at 28%-30% Lithopone and 60% Lithopone.
It doesn’t take much to imagine what they must be doing to our poor skin each day as we layer on our sunscreen, foundation, concealers, eyeshadows & lip sticks which all contain large doses of titanium dioxide.
Lithopone is used in water-based paints because of its excellent alkali resistance. It is also used as a whitener and reinforcing agent for rubber and as a filler and whitener for paper.
