- In terms of manufacturers, there is a select group that stands out for their commitment to quality, innovation, and reliability
- The chemical industry also finds Lithopone 28-30% to be a valuable additive. It is often used as a filler in plastics, rubber, and other polymers to improve their mechanical strength, wear resistance, and electrical conductivity. Moreover, its chemical inertness makes it suitable for use in products that come into contact with corrosive substances.

You see sometime ago, before they changed their warranty to exclude sunscreen damage, Bluescope Steel were getting countless warranty claims for peeling paint. All curiously shaped in fingerprint patterns around the edge of their metal sheets. This was a little perplexing & financially worrying for the bosses at Bluescope steel so they got some clever scientists to test the damaged roof sheets.

Titanium dioxide is a common pigment, and zinc oxide and magnesium oxide are common fillers in rubber base adhesives.

The toxicity of P25TiO2NPs was evaluated in both prokaryotic (Fig. 3) and eukaryotic cells (Fig. 4). The XTT assay was chosen to measure the cell viability in bacterial cultures of MSSA, a normal skin microbiota microorganism. The reduction in the viability of samples with bare NPs is notorious, possibly due to the described ROS production from the interaction of P25TiO2NPs with light [37]. This effect seems to be avoided when they are functionalized with vitamin B2. Also, the most concentrated vitaminB2@P25TiO2NPs sample (0.2 mg/mL) shows up to 60% more absorbance after 6 h compared to the bare NPs (due to normal cell replication). This may indicate that the antioxidant effect of the vitamin B2 coating is greater than the oxidation damage produced by the NPs. This protective capacity could be attributed to the glutathione redox cycle and the conversion of reduced riboflavin to its oxidized form [38]. Values of cell viability greater than 100% are not rare and could be understood because the XTT assay actually measure metabolic activity when reducing the tetrazole to formazan. It is usually assumed that conversion is dependent on the number of viable cells, but it could also be related to an expected increased enzymatic activity when cells are exposed to small doses of some new substance. Further analysis showed that this effect was not the only one responsible for better cell viability of vitaminB@P25TiO2NPs treated samples.

Barium sulfide is produced by carbothermic reduction of barium sulfate. Zinc sulfate is obtained from a variety of zinc products, often waste, by treatment with sulfuric acid.
- Properties:
Lithopone is the ideal combination of the white pigment zinc sulfide and the white spacer Blanc fixe. Due to the particle distribution of the ZnS (0.35 µm) and BaSO4 (0.8 -1.0 µm), which is the result of a co-precipitation (not mixing) and co-calcination, a high packing density is achieved, which in turn gives Lithopone its low resin demand and excellent rheological properties. - Another advantage of using titanium dioxide in plastic manufacturing is its UV-blocking capabilities. The pigment absorbs ultraviolet radiation, which helps to prevent the degradation of the plastic material caused by exposure to sunlight. This not only prolongs the lifespan of the product but also protects it from fading and discoloration over time This not only prolongs the lifespan of the product but also protects it from fading and discoloration over time

A few processes are used to produce TiO2 pigment. Rutile TiO2 is found in nature. This is because the rutile crystal structure is the thermodynamically stable form of titanium dioxide. In chemical processes natural TiO2 can be purified, thus obtaining synthetic TiO2. The pigment can be made from ores, rich in titanium, that are mined from the earth.
Two chemical routes are used to make both rutile and anatase TiO2 pigments.
As for titanium dioxide, the FDA approved titanium dioxide for use as a food additive in 1966. The last time the agency reviewed the additive’s safety, according to the Guardian, was in 1973.


Lithopone 30% CAS No. 1345-05-7 / Application
3.Used for coloring rubber products, varnishes, leather, paper, enamel, etc.
Not everyone agrees, though. The European Commission banned titanium dioxide as a food additive in the European Union in 2022.
Throughout the fourth quarter of 2021, the European market had consistent optimistic sentiment. Despite the overwhelming inventories at lower levels during the fourth quarter of 2021, the demand prognosis in the domestic market revealed varied opinions. Imports from the Asia Pacific region, on the other hand, remained disruptive due to limited accessibility of vessel freights and a decrease in the PMI index for titanium dioxide in China despite the application of severe environmental protection measures.
Moreover, titanium dioxide is also used in rubber formulations to improve the processing and curing properties of rubber compounds. It acts as a catalyst in the vulcanization process, speeding up the cross-linking of rubber molecules and enhancing the overall performance of the final product. This results in rubber products that are stronger, more flexible, and better suited for a wide range of applications.
This regulation entered into force on 7 February 2022. However, the Regulation included a six-month transitional period to allow food businesses time to phase out the use of this food additive and to reformulate their products using suitable alternatives. This period will end on 7 August 2022.
