Ultramarines

What is Ultramarines?

Ultramarines consist of a family of brilliant blue, violet, red, and pink pigments produced synthetically from kaolin clay, sodium carbonate, and sulfur through high-temperature calcination. These complex silicates, primarily sodium aluminum sulfosilicates, belong to the category of inorganic colorants widely used in makeup products like eyeshadows, blushes, lipsticks, and nail polishes. They function by dispersing evenly in formulations to impart consistent, lightfast hues that resist fading or bleeding, ensuring product stability across batches and during application. Insoluble in water and oils, ultramarines remain on the skin's surface without penetrating, providing opacity and coverage without altering product texture significantly. Regulatory bodies affirm their use in cosmetics at typical concentrations.
