  • Applications

    Betanin (CAS 7659-95-2) is a natural red pigment in the betalain family, widely recognized as a colorant derived from beetroot. In food processing, it serves as a natural colorant for foods and beverages. In cosmetics and personal care, it is used as a natural pigment in makeup and skincare products. In coatings and inks, it can function as a natural dye for water-based paints, coatings, and printing inks. In textiles, it is used as a natural dye for fabric dyeing, subject to local regulations and formulation stability.
