Ultramarine Violet Technical Specifications
|
Applications:
Colors used in the Cosmetic Industry can be grouped into two categories: FDA Certified Organics and Inorganic Pigments.
Inorganic pigments are controlled by the Food and Drug Administration. Prior to 1960, the only requirements for inorganic pigments were that they meet heavy metal concentrations as specified by the FDA. A listing of these color additives and requirements can be found in the Code of Federal Regulations 21, Part 73. All of our products are tested and certified to meet these standards. Inorganic pigments are primarily used in pigmented face powders, foundations, blushers, nail lacquers and cosmetics used in the area of the eye such as mascaras, eyeshadows, liners, etc.
Ultramarines
The ultramarine family of colors include blue, pink and violet. Ultramarine blues are synthetically produced sodium alumino sulpho silicates. Further oxidation of one of the finer particle size red shade blue produces violet. The redness of hue depends on the degree of oxidation. An ion exchange reaction with violet produces pink. They are easily dispersed in aqueous media, have excellent light stability and are very stable in alkali (ph of 7 or higher) compounds. Ultramarines are extremely acid sensitive and will release hydrogen sulfide in acid conditions. However, there is a silica coated ultramarine blue that resists mild acid conditions. Their primary use is in eye products such as shadows and eye pencils as well as in bar soaps.
