Description

Copper Chlorophyll is a stable, oil-soluble green pigment derived from chlorophyll, where the central magnesium ion is replaced by copper. This modification provides exceptional color stability and resistance to heat and light compared to natural chlorophyll, making it a vital ingredient for consistent product coloration. It is primarily utilized as a safe and effective colorant in the food, cosmetic, and pharmaceutical industries, where a vibrant green hue is desired.

Application

• Food & Beverage Coloring: Used in candies, chewing gum, ice cream, dairy products, beverages, and pasta to impart a stable green color.
• Cosmetics & Personal Care: Incorporated into soaps, shampoos, creams, lipsticks, and other products as a natural-looking color additive.
• Pharmaceuticals: Employed as a colorant in tablets, capsules, ointments, and syrups for product identification and aesthetic appeal.
• Dietary Supplements: Included in health supplements for its potential antioxidant properties and as a source of chlorophyllin complexes.
• Industrial Applications: Used in the coloring of oils, waxes, and other non-food products requiring a green pigment.
