In addition to its UV protection properties, P25 TiO2 also offers high photocatalytic activity. When exposed to sunlight, it can break down organic compounds and pollutants, making it an effective agent for environmental remediation. This property makes P25 TiO2 a valuable addition to paints and coatings, as it can help reduce the amount of volatile organic compounds (VOCs) released into the atmosphere, thereby contributing to air quality improvement.

Having thus described the origin and uses of the pigment, we now come to the question, what is lithopone? It is, in short, a chemical compound usually consisting of 30.5 per cent zinc sulphide, 1.5 per cent zinc oxide and 68 per cent barium sulphate, but these proportions vary slightly in the different makes. Lithopone of this composition is sold as the highest grade, either as red seal or green seal, as it best suits the idea of the manufacturer. Many manufacturers, especially in Europe, sell and also export other brands under other seals, containing 24, 20, 18 and as little as 12 per cent of zinc sulphide with very small percentages of zinc oxide, the balance being usually barium sulphate, but sometimes certain portions of China clay or gypsum (calcium sulphate) or whiting (calcium carbonate). Such brands are not a chemical compound, but mechanical mixtures of the chemically compounded lithopone and the admixtures referred to.
