Moving forward to 2045, we project a world that will be vastly different from today. The term singularity comes to mind, referring to a hypothetical future point where technological growth becomes uncontrollable and irreversible, resulting in unforeseeable changes to human civilization. Experts predict that by 2045, advancements in fields such as AI, biotechnology, and quantum computing will accelerate at an unprecedented rate. We might find ourselves coexisting with highly advanced AI systems capable of performing tasks beyond human capability, sparking debates on ethics, governance, and the nature of consciousness. In terms of the economy, the shift towards automation and AI-driven processes could lead to a significant change in employment patterns, potentially leaving behind traditional job roles in favor of more innovative, tech-centric positions.

  • Other scientists, however, have called into question the experimental designs of such studies, citing inconsistent results specifically in studies used to test DNA damage.

  • English name: Lithopone

  • 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. 

  • Moreover, China's stringent environmental regulations have driven the industry to adopt more eco-friendly production methods. Many manufacturers have invested in advanced technologies to reduce waste, minimize energy consumption, and lower emissions during the production of R996. This commitment to sustainability aligns with the global trend towards green manufacturing.
  • The aim of this work was to examine particularly the Degussa P25 titanium dioxide nanoparticles (P25TiO2NPs) because they are among the most employed ones in cosmetics. In fact, all kinds of titanium dioxide nanoparticles (TiO2NPs) have gained widespread commercialization over recent decades. This white pigment (TiO2NPs) is used in a broad range of applications, including food, personal care products (toothpaste, lotions, sunscreens, face creams), drugs, plastics, ceramics, and paints. The original source is abundant in Earth as a chemically inert amphoteric oxide, which is thermally stable, corrosion-resistant, and water-insoluble. This oxide is found in three different forms: rutile (the most stable and substantial form), brookite (rhombohedral), and anatase (tetragonal as rutile), of these, both rutile and anatase are of significant commercial importance in a wide range of applications [3]. Additionally, the nano-sized oxide exhibits interesting physical properties, one of them is the ability to act as semiconducting material under UV exposure. In fact, TiO2NPs are the most well-known and useful photocatalytic material, because of their relatively low price and photo-stability [4]. Although, this photoactivity could also cause undesired molecular damage in biological tissues and needs to be urgently assessed, due to their worldwide use. However, not all nanosized titanium dioxide have the same behavior. In 2007, Rampaul A and Parkin I questioned: “whether the anatase/rutile crystal form of titanium dioxide with an organosilane or dimethicone coat, a common titania type identified in sunscreens, is appropriate to use in sunscreen lotions” [5]. They also suggested that with further study, other types of functionalized titanium dioxide could potentially be safer alternatives. Later, Damiani found that the anatase form of TiO2NPs was the more photoactive one, and stated that it should be avoided for sunscreen formulations, in agreement with Barker and Branch (2008) [6,7].

  • Regulatory agencies around the world are currently working to establish guidelines for the safe use of TiO2 in consumer products and water supplies. In the meantime, consumers can take steps to minimize their exposure to TiO2 by choosing products that do not contain the pigment and using water filters that can remove nanoparticles.
  • The integrity of surface skin cells was evaluated with and without solar simulated irradiation. The integrity of the stratum corneum was significantly lower in individuals treated with P25TiO2NPs under the light in comparison to the ones that received the functionalized nanoparticles. Cell membrane suffering is evident (Fig. 9), and it is in accordance with the ROS levels and macromolecule oxidation found in vitro for the irradiated P25TiO2NPs. Disruption of the superficial skin layer was observed in all animals treated with no functionalized nanoparticles, under irradiation. This data expands the findings by the group of Professors Fubini and Fenoglio, who showed that P25TiO2NPs could impact the lipid structure at the top few microns of the stratum corneum [55]. Control skin under irradiation and without any topic formulation did not show changes in cell structure.

  • Stability and darkening

  • Can darken in the presence of iron.
  • Anatase titanium dioxide, with its 98% purity, offers a range of benefits that make it an ideal choice for paint formulations. Its unique crystal structure imparts excellent ultraviolet (UV) resistance, which safeguards painted surfaces from fading and degradation over time. Furthermore, its high refractive index contributes to exceptional hiding power and gloss retention, enhancing the aesthetic appeal of coatings.
  • When it comes to cost-effectiveness, titanium dioxide is a relatively inexpensive raw material. Its low price point makes it an attractive option for manufacturers looking to reduce costs without sacrificing quality. However, the price of titanium dioxide can vary depending on factors such as purity, particle size, and production methods.
  • In conclusion, when sourcing anatase titanium dioxide pigment, it is essential to partner with a reputable supplier that offers competitive prices, high-quality pigment, reliability, and superior customer service. By taking the time to evaluate these factors, you can find a supplier that meets your needs and helps you achieve success in your industry.

  • The properties of lithopone are very suitable for use in the production of coatings. Because the ingredients of lithopone are zinc sulfide and barium sulfate, and the more zinc sulfide content, the stronger its covering power. This indicates a paint product with strong white covering power. It is different from water in that it reacts with acid but does not react with alkali. It has a wide range of uses. Because its structural properties are similar to titanium dioxide and its price is relatively cheap, it can also be used as a substitute for some titanium dioxide. Lithopone can be used for coloring paints, inks, pigments, rubber, paper, leather, enamel, etc.

  • There are many suppliers of barium sulfate in the market, each offering different prices and levels of quality. Some suppliers may offer lower prices, but their products may not meet the required specifications. On the other hand, some suppliers may offer higher prices but provide superior quality products. It is important to strike a balance between price and quality when choosing a supplier for barium sulfate.
  • Prof. Matthew Wright, chair of EFSA’s working group on E171, noted: “Although the evidence for general toxic effects was not conclusive, on the basis of the new data and strengthened methods we could not rule out a concern for genotoxicity and consequently we could not establish a safe level for daily intake of the food additive.”
