- The pH of titanium dioxide refers to its acidity or alkalinity level, which can greatly affect its dispersibility, stability, and performance. Typically, titanium dioxide is most stable and exhibits its optimal properties at neutral pH levels, around 7.0. At this pH, the titanium dioxide particles are well-dispersed and have maximum brightness and opacity.
- Anatase titanium dioxide pigment is a popular choice for manufacturers in a variety of industries, including paints, coatings, plastics, and cosmetics. This high-quality pigment is valued for its superior opacity, brightness, and UV resistance, making it an ideal choice for products that require long-lasting color and protection.

- In conclusion, while both lithopone and titanium dioxide have their advantages and disadvantages, TiO2 appears to be the better choice for most applications. Its superior whiteness, UV protection properties, and chemical stability make it a popular choice in the paint, plastics, and paper industries. However, for applications where cost and safety are primary concerns, lithopone may still be a viable option. Ultimately, the choice between these two pigments will depend on the specific requirements of the application and the desired balance of performance and cost.
- In addition to these traditional uses, titanium dioxide is gaining popularity in emerging fields such as photocatalysis and solar energy conversion
Ref. 18% TiO2 - Our manufacturing process for lithopone involves carefully selecting high-quality raw materials and utilizing advanced technology to ensure consistent and superior product quality. We take great pride in our state-of-the-art facilities and skilled workforce that help us maintain strict quality control measures throughout the production process.
- In addition to technological advancements, TiO2 factories are increasingly focused on sustainability. They implement eco-friendly practices such as wastewater recycling, energy recovery systems, and the use of renewable energy sources. Some factories even collaborate with local communities to promote environmental awareness and support conservation efforts.

Titanium dioxide is widely used as a color-enhancer in cosmetic and over-the-counter products like lipsticks, sunscreens, toothpaste, creams, and powders. It’s usually found as nano-titanium dioxide, which is much smaller than the food-grade version (7Trusted Source).
It’s also used in food products to provide a white color. Candies, cakes and creamers are examples of foods that may contain titanium dioxide for its color enhancing and bleaching properties.
The Regulation sets out a requirement ofcancer warning labels for mixtures in powder form containing 1% or more of titanium dioxide particles with an aerodynamic diameter of ≤ 10 µm. Although other forms and mixtures do not fall under this classification, there are specific warnings that need to be applied to those that contain more than 1% of titanium dioxide.Thusfive hundred and sixty-three pounds of a seventeen-per-ccnt. grade of lithopone will be precipitated, from which the soda liquor may be filtered and then washed out. Fifty six pounds of sodium hydrosulfid may then be recovered from the solution, if no further treatment thereof is contemplated, by any suitable evaporating process. By employing sodium sulfate and suitably altering the reaction I have also produced lithopone and sogo dium sulfid. The products of these reactions will be found to be of unusual purity and require no subsequent treatment for placing them upon the market.Nano, or ultrafine, TiO2 comprises primary particles sized less than 100nm. In this grade, titanium dioxide is transparent (colourless) and boasts improved UV scattering and absorbing properties compared with larger particle-size pigmentary TiO2.
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.
