SHIKONIN CAS 517-89-5

Shikonin is a natural naphthoquinone compound extracted from the roots of Lithospermum erythrorhizon (purple gromwell). It appears as a deep red to purple pigment with a subtle earthy and woody aroma. Known for its intense coloring properties, shikonin is used in natural dyes, cosmetics (such as lipsticks and soaps), and traditional formulations for skin applications. Oil‑soluble and sensitive to light, it is often stabilized in carrier oils for external use.
