Description

Sodium Copper Chlorophyllin is a water-soluble, semi-synthetic derivative of chlorophyll, stabilized by replacing the central magnesium ion with copper and saponifying the phytol tail. This modification provides exceptional stability and a vibrant green color, making it a highly sought-after natural colorant and functional ingredient. It is primarily utilized by manufacturers in the food, beverage, pharmaceutical, and cosmetic industries seeking consistent, safe, and effective green pigmentation.

Application

• Food & Beverage Coloring: Used as a natural green colorant (E141) in candies, ice cream, dairy products, beverages, and pasta.
• Dietary Supplements & Nutraceuticals: Incorporated into capsules, tablets, and powders for its purported antioxidant and deodorizing properties.
• Pharmaceuticals: Employed as a safe coloring agent in syrups, ointments, and tablets, and investigated for therapeutic applications.
• Cosmetics & Personal Care: Adds natural green color to soaps, toothpastes, mouthwashes, and skincare products.
• Oral Hygiene Products: Valued for its coloring and potential breath-freshening effects in mouthwashes and chewing gums.
• Industrial Applications: Used in research, as a dye for textiles, and in other specialized chemical processes.
