1. Introduction

Sodium copper chlorophyllin is a water-soluble green pigment and antioxidant derived from chlorophyll, in which magnesium is replaced by Cu²⁺ and the phytol tail is removed. It is used in the food industry, medicine for deodorization, and cosmetics as an antioxidant and anti-inflammatory agent.

Chlorophyllin is obtained from plant chlorophyll by alkaline saponification and replacement of Mg²⁺ with Cu²⁺. Water solubility, heat resistance, and pH stability make it a convenient food colorant (E141) and functional ingredient in nutraceuticals and cosmetics. It can bind volatile sulfur compounds, reducing odors.

2. Chemical Structure & Synthesis

• Starting material: Chlorophyll a – porphyrin ring with central Mg²⁺ and phytol tail (C₅₅H₇₂MgN₄O₅)

• Saponification: Alkaline treatment removes phytol tail

• Metal replacement: Mg²⁺ is displaced by Cu²⁺ to form copper chlorophyllin (approximately C₄₂H₄₀CuN₄O₆Na₂)

3. Properties

• Appearance: Dark green powder or granules

• Solubility: Freely soluble in water at pH 4–10

• Stability: Resistant to heat treatment, light, and acidic environments (pH range 3–11)

• Molecular weight: Varies depending on degree of polycondensation and hydrolysis

4. Applications

• Food industry: Natural green colorant (E141)

• Medicine and nutraceuticals: Internal deodorizing agents, antioxidant support

• Cosmetics: Added to care products for odor neutralization and oxidation protection

5. Conclusion

Sodium copper chlorophyllin is a versatile water-soluble pigment with antioxidant and deodorizing properties. It is safe for food and cosmetic use and is actively being studied in nutraceutical formulations for reducing inflammation and binding toxins.
