Description

Carmine is a vibrant, natural red colorant derived from the cochineal insect, primarily used as a stable pigment and dye. This product is valued for its excellent light and heat stability, making it a superior alternative to many synthetic red dyes in applications where natural sourcing is required. It is essential for manufacturers in the food, cosmetic, and pharmaceutical industries seeking to enhance product appeal with a trusted, natural color. Carmine CAS NO 1328-60-5 offers reliable performance for creating rich red to purple hues.
