Description

Sodium Zinc Chlorophyllin is a semi-synthetic, water-soluble derivative of chlorophyll, where the central magnesium ion is replaced by zinc and the phytyl tail is removed. This modification significantly enhances its stability, color intensity, and bioavailability compared to natural chlorophyll. It is a vital green colorant and functional ingredient sought by manufacturers in the food, pharmaceutical, and cosmetic industries for its safe and vibrant pigmentation properties.

Application

• Food & Beverage Coloring: Used as a natural green colorant (E141ii) in confectionery, dairy products, beverages, ice cream, and pasta.
• Pharmaceutical Formulations: Employed as a safe excipient for coloring tablets, capsules, syrups, and ointments.
• Cosmetics & Personal Care: Incorporated into soaps, shampoos, creams, and lotions for its natural green hue and potential skin-soothing properties.
• Dietary Supplements: Utilized in health supplements for its antioxidant properties and as a source of bioavailable chlorophyll derivatives.
• Oral Hygiene Products: Added to mouthwashes and toothpastes for its deodorizing effect and natural color.
• Diagnostic & Research Reagents: Serves as a biochemical stain and marker in laboratory and clinical diagnostic applications.

Quality Control

Our Sodium Zinc Chlorophyllin is manufactured under strict quality management systems. We ensure compliance with relevant food and pharmaceutical grade specifications, including FCC (Food Chemicals Codex) and EU Directive (E141ii) standards. Each batch is tested for identity, purity, heavy metals, and microbiological safety. Certificates of Analysis (COA) are available upon request to guarantee traceability and consistent quality for your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent moisture absorption and caking.
