Ultramarine Blue

KT-40001 is a cosmetic grade Ultramarine Blue — a synthetic inorganic pigment that provides a clean, bright violet-blue body color with excellent opacity and low heavy metal content suitable for use across personal care and color cosmetic formulations. Unlike organic blue dyes, Ultramarine Blue is chemically inert, non-migrating, and inherently lightfast — properties that make it a reliable choice for pressed powders, eye shadows, lip products, and soap where color stability over shelf life is a baseline requirement. All Kolortek cosmetic oxide grades are filtered to remove regulated impurities before supply.
