Suppliers of lithopone have recognized the growing need for high-quality, reliable products that meet both industry standards and consumer preferences. They have invested in advanced production techniques and stringent quality control measures to ensure that their lithopone products deliver consistent performance. This commitment to quality allows paint formulators to achieve the desired properties in their final products, such as enhanced durability, improved hiding power, and superior color stability over time.

We know that there are a lot of suspended organisms and colloidal impurities in natural water. The forms of suspended solids are different. Some large particles of suspended solids can settle under their own gravity. The other is colloidal particles, which is an important reason for the turbidity of water. Colloidal particles can not be removed by natural settlement, because colloidal particles in water are mainly clay with negative electricity The Brownian motion of colloidal particles and the hydration on the surface of colloidal particles make colloidal particles have dispersion stability. Among them, electrostatic repulsion has the greatest influence. If coagulant is added to water, it can provide a large number of positive ions and accelerate the coagulation and precipitation of colloid. Compressing the diffusion layer of micelles makes the potential change into an unstable factor, which is also conducive to the adsorption and condensation of micelles. The water molecules in the hydrated film have fixed contact with the colloidal particles and have high elastic viscosity. It is necessary to overcome the special resistance to expel these water molecules. This resistance hinders the direct contact of the colloidal particles. The existence of some hydrated films depends on the electric double layer state. If coagulant is added to reduce the zeta potential, the hydration may be weakened. The polymer materials formed after coagulant hydrolysis (the polymer materials directly added into water generally have chain structure) play an adsorption bridging role between the colloidal particles. Even if the zeta potential does not decrease or does not decrease much, the colloidal particles can not contact each other and can be adsorbed through the polymer chain Colloidal particles can also form flocs.

The annual production capacity of high-grade rutile titanium dioxide has reached more than 400,000 tons. It is one of the largest TiO2 manufacturers in China at present. It has more than ten product brands of Taiohua, Jinxing and other brands, and its products are sold in more than 50 countries and regions around the world. It has long maintained the excellent performance of the second overall ranking in the domestic titanium dioxide industry.

Dongfang Titanium Industry R-5568 titanium dioxide with zinc salt stabilizer, zirconium, aluminum, silicon coating. It has the characteristics of high blue phase, easy dispersion, high weather resistance, high hiding power, low oil absorption, good system compatibility, and excellent processing rheology. It is a high-quality titanium dioxide for plastics. Dongfang Titanium R-5568 titanium dioxide is recommended to be widely used in polyolefin, PVC, ABS, PS and other color masterbatches, profiles, plates and pipes, and can also be used in leather color paste, oily paint and other industries.

In a 2020 study published in the Journal of Trace Elements in Medicine and Biology, researchers conducted an in vitro experiment to analyze the effects of TiO2 nanoparticles on a human neuroblastoma (SH-SY5Y) cell line. The scientists evaluated “reactive oxygen species (ROS) generation, apoptosis, cellular antioxidant response, endoplasmic reticulum stress and autophagy.” The results showed that exposure to the nanoparticles “induced ROS generation in a dose dependent manner, with values reaching up to 10 fold those of controls. Nrf2 nuclear localization and autophagy also increased in a dose dependent manner. Apoptosis increased by 4- to 10-fold compared to the control group, depending on the dose employed.” 

Partial substitution of titanium dioxide in liquid paints 

Nano-sized P25TiO₂NPs were kindly donated by Dr. Scaiano, Ottawa University (Canada). Riboflavin (vitamin B2) was from Sigma and ascorbic acid (vitamin C) and KBr (for IR pills) were from Cicarelli. Base cream for the animal experiments was purchased from Todo Droga and the LED panel was built ad hoc.

However, since it’s photosensitive — meaning it can stimulate free radical production — it’s usually coated in silica or alumina to prevent potential cell damage without reducing its UV-protective properties (7Trusted Source).

Ultimately, it comes down to whether you want to take the risk of having Titanium Dioxide in your blood stream?

We have long been passionate about avoiding exposure to Titanium Dioxide & are proud that our products offer a safe alternative to Women everywhere. We strongly urge you to ditch your toxic, unsafe makeup & find a safer alternative.

In a study published in 2022 in the journal Particle and Fibre Technology, researchers examined the impact of maternal exposure to titanium dioxide nanoparticles in newborn offspring mice. They found that “a chronic exposure to TiO2 NPs during pregnancy alters the respiratory activity of offspring, characterized by an abnormally elevated rate of breathing.” Breathing was also shown to be “significantly and abnormally accelerated,” and the ability for neural circuitry to effectively adjust breathing rates was impaired. The researchers concluded: “Our findings thus demonstrate that a maternal exposure to TiO2 NPs during pregnancy affects the normal development and operation of the respiratory centers in progeny.”

There's also evidence that inhaling titanium dioxide particles can be dangerous. That's mainly a concern for industrial workers. In places where it's produced, or where it's used to make other products, workers can breathe it in as a dust. The Occupational Health and Safety Administration has exposure standards manufacturers must meet.
