Synthetic dyes are produced from various chemicals. The great majority of dyes are obtained in this way because of their superior cost, optical properties (color), and resilience (fastness, mordancy). [2] Both dyes and pigments are colored, because they absorb only some wavelengths of visible light. Dyes are usually soluble in some solvent ...
Persian blue: made by grinding up the mineral Lapis lazuli. The most important mineral component of lapis lazuli is lazurite (25% to 40%), a feldspathoid silicate mineral with the formula (Na,Ca) 8 (AlSiO 4) 6 (S,SO 4,Cl) 1–2. Cobalt pigments. Cobalt blue (PB28): cobalt(II) aluminate. Cerulean blue (PB35): cobalt(II) stannate. Cerium uranium blue

Between 1877 and 1887, 130 German patents for azo dyes were filed and 105 new dyes made it to market. [13] It also lead to a difference in how chemical companies interacted with consumers. German dye firms developed in-house marketing and distribution capabilities coordinated directly with their research and development departments. [ 3 ]
This act forbids the use of artificial colorings red dye No. 40, yellow dyes Nos. 5 and 6, blue dyes Nos. 1 and 2, and green dye No. 3 from foods served in schools.
The International Organization for Standardization (ISO) develops technical standards for the manufacture of pigments and dyes. ISO standards define various industrial and chemical properties, and how to test for them. The principal ISO standards that relate to all pigments are as follows: ISO-787 General methods of test for pigments and extenders.
Occasionally, enjoying processed foods with some of these ingredients likely won't cause any harm, but eating multiple sources of chemicals and dyes on a daily basis over a long period of time can ...
