Polyacrylamide is utilized in water treatment primarily as a flocculant—a substance that encourages the clumping of particles, which can then be removed from water. While this aids in purifying water and removing sediments, the challenge lies in ensuring that the acrylamide residuals do not pose a risk to consumer health.

Developing new Lithopone formulations, one that enhances the properties of the existing Lithopone is anticipated to boost the demand for Lithopone white pigment during the forecast period. Reinforced Lithopone is one such development, wherein a copolymer is added to the polymerization reaction to yield Lithopone with an increased weather resistance and an anti-ultraviolet property. Moreover, development of nano-scale Lithopone is also anticipated to attract market interest during the forecast period.

Prof. Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), wrote of the decision: “Taking into account all available scientific studies and data, the Panel concluded that titanium dioxide can no longer be considered safe as a food additive. A critical element in reaching this conclusion is that we could not exclude genotoxicity concerns after consumption of titanium dioxide particles. After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body.”
Both P25TiO2NPs (with or without vitamin B2) were not found beyond the epidermis in 99% of the analyzed TEM images (Fig. 8). This is coherent with previous findings showing that nanoparticles greater than 50 nm can not penetrate the skin, even in vivo models with movement, stretching, and friction [54]. However, in one of the zones, a few nanoparticles were observed inside a hair follicle. This could be due to the follicle exposure after the localized rupture of this physical barrier when rats were shaved in order to clean the area for cream topical administration. This finding suggests that nanoparticle-based sunscreen should not be applied on recently shaved or harmed skin, in order to avoid nanoparticle skin penetration.
Lithopone is the re-discovered white pigment with functional properties suitable for several applications.
