CI 42051
What is CI 42051?
CI 42051 is a synthetic triarylmethane dye, chemically a trisodium salt derived from sulfonated aromatic compounds through industrial synthesis processes. It originates from petrochemical sources and is purified to high standards for cosmetic applications. Primarily used in rinse-off products such as shampoos, bath gels, soaps, and some makeup items, it functions as a water-soluble colorant. In formulations, it disperses evenly to absorb certain light wavelengths, reflecting an intense blue shade that remains stable against light, heat, and pH variations common in cosmetics. This enables manufacturers to achieve uniform batch coloring and enhance product aesthetics without affecting texture or performance.
