FDA guidelines:Americans are eating too much salt. So the FDA wants food manufacturers to cut back on sodium.
The refractive index, represented by the letter n, of a material describes how light propagates through and is bent by, that material. The magnitude of the refractive index, depending upon the electronic structure of the molecules, governs to what extent the path of light changes, when entering or leaving a material.
Particles in a matrix, like pigment particles surrounded by the binder system in a coating, ink or plastic, can change the propagation direction of light when the particles and the matrix have a different refractive index. This phenomenon, called scattering, results in both white color (provided that the particles do not absorb visible light) and the hiding power of the coating.Numerous studies have linked titanium dioxide to genotoxicity and cytotoxicity. Genotoxicity refers to a chemical’s potential to cause DNA damage, which can, in turn, lead to cancer. Cytotoxicity is a general term that refers to a characteristic of being harmful to cells.
- In addition to producing TiO2 pigment, some factories also offer custom blending and color matching services to meet the specific requirements of their customers. This allows industries such as paint manufacturers to create unique shades and colors by blending different pigments to achieve the desired results.
The updated evaluation revises the outcome of EFSA’s previous assessment published in 2016, which highlighted the need for more research to fill data gaps.
- In the realm of product development, TIO2 pigment manufacturers are also focusing on creating specialized grades for niche applications. For instance, antimicrobial TIO2 pigments can be used in healthcare settings to prevent infection, while photocatalytic TIO2 can help in air purification systems by breaking down harmful pollutants.
