  • Applications

    Delphinidin-3-O-rhamnoside chloride (CAS 29907-19-5) is an anthocyanin glycoside derived from plant sources and commonly used as a natural pigment. In food processing and beverages, it serves as a natural colorant, imparting red to blue hues that vary with pH. In cosmetics and personal care, it is employed as a natural colorant for formulations such as lip products, creams, and cleansers where permitted. In coatings and inks, it can function as a natural pigment for decorative finishes and printing applications. In polymers and plastics, it is being researched as a colorant additive for resins and compounds. Additionally, it is evaluated in research contexts for antioxidant activity and as a potential color-sensing component (e.g., pH indicators), subject to formulation limits and local regulations.
