Project Description
Product Description
Sodium Copper Chlorophyllin is a synthetic pigment produced by refined processing of sodium copper chlorophyllin. Sodium copper chlorophyll is made by refining the extracted chlorophyll through saponification, copperization and other reactions.
supplementation of this substance in cancer patients can inhibit the activity of cancer and avoid the phenomenon of metastasis and spread of cancer.

Benefits
- Natural Green Colouring Solution
Sodium Copper Chlorophyllin provides a stable, vivid green hue that serves as an effective natural alternative to synthetic green dyes. It meets the growing consumer demand for clean-label products and allows manufacturers to achieve consistent colour performance without relying on artificial additives.
- Superior Stability
Compared to untreated chlorophyll, Sodium Copper Chlorophyllin offers excellent stability under typical processing conditions. It remains stable across a pH range of 3.5 to 7.0 and withstands standard pasteurisation temperatures, making it suitable for a variety of manufacturing environments, including beverages, confectionery, and processed foods.
- Multi-Functional Application
Beyond its colouring function, the ingredient is widely recognised in oral care products, where it serves as a natural breath-freshening component. This dual functionality provides additional formulation value, particularly in toothpaste and mouthwash products.
- Regulatory Compliance
Sodium Copper Chlorophyllin is approved as a food colourant (E141) under EU regulations and is listed in the FCC and JECFA standards. It is also permitted for use in cosmetic and personal care products in multiple global markets. This wide regulatory acceptance simplifies the compliance process for formulators and brand owners.
Application
Sodium Copper Chlorophyllin is a versatile ingredient suitable for a range of food, beverage, and personal care products. Its stable green colour and clean-label positioning make it an excellent natural alternative to synthetic green dyes. The recommended use levels provided below are general starting points. Actual usage levels should be determined based on the specific formulation, target shade, regulatory limits, and local market acceptance of the finished product.
- Beverages
Sodium Copper Chlorophyllin is used in beverages to create an attractive, natural green colour in products such as sports drinks, ready-to-drink teas, fruit juices, energy drinks, flavoured waters, and functional beverages. A typical starting usage level is 0.01% to 0.05% , with adjustment based on the desired shade intensity. The ingredient is stable in acidic conditions (pH 3.5–7.0) and is compatible with standard beverage production processes. For clear beverages, we recommend pre-dissolving the powder in a small portion of water before addition to ensure even dispersion.
- Confectionery
In confectionery applications, Sodium Copper Chlorophyllin is used in hard candies, gummies, chewing gums, jellies, and cake icings to provide a consistent and appealing green colour. Recommended usage levels typically range from 0.01% to 0.1% , depending on the product and shade requirements. The ingredient maintains colour stability under common confectionery processing conditions. It offers a natural colour alternative for sugar-free and low-sugar formulations.
- Toothpaste & Oral Care
Sodium Copper Chlorophyllin is widely used in toothpaste, mouthwash, and other oral care products for its natural green colouring and as a breath-freshening ingredient. It is often included in formulations aimed at providing a natural, plant-derived image. The typical usage level is 0.1% to 0.5% in toothpaste gels and 0.01% to 0.05% in mouthwash. It shows good stability in oral care formulations and is compatible with common toothpaste ingredients.
- Other Food Applications
Sodium Copper Chlorophyllin is also used in a variety of other food products, including: sauces and dressings, canned vegetables, processed meat products, and snack seasonings. For these applications, a starting usage range of 0.005% to 0.05% is recommended, with adjustment according to the specific product and desired colour. As with all applications, the final use level should be confirmed through small-scale trials.
Storage & Stability Recommendations
Proper storage is essential to ensure that Sodium Copper Chlorophyllin maintains optimal colour performance, stability, and functional properties throughout its shelf life. The following recommendations are designed to help procurement professionals and formulators optimise the ingredient‘s performance and extend its usable life.
Sodium Copper Chlorophyllin should be stored in a cool, dry environment, with temperatures maintained between 15°C and 25°C and relative humidity kept below 60%. Protection from light is a critical requirement, as the ingredient is sensitive to light exposure, and ultraviolet radiation accelerates colour fading. Opaque or dark-coloured containers should be used, and containers must be kept tightly sealed at all times after opening to prevent moisture absorption and oxidation.
Under standard storage conditions, the shelf life is 24 months from the date of manufacture for powder forms, and 12 months for liquid forms. After opening, it is recommended to use the product within 6 months to achieve optimal colour intensity and performance.
For finished products formulated with Sodium Copper Chlorophyllin, such as beverages, the ingredient demonstrates good stability under standard pasteurisation conditions (for example, 85°C for 15 to 20 seconds). For ultra-high temperature processing or extended high-temperature exposure, small-scale stability trials are recommended to confirm colour retention under the specific production conditions. Finished products should be protected from prolonged exposure to direct light; using light-protective packaging is the recommended practice to extend the product’s visual shelf life.
The ingredient is compatible with commonly used food preservatives and antioxidants. During storage, it should be kept away from strong acids, strong alkalis, or substances with strong odours to prevent cross-contamination. For long-term storage, periodic checks of the product‘s appearance, colour, and flowability are recommended to ensure no abnormal changes such as caking, discolouration, or off-odours have occurred. If any deviation from specifications is observed, it is advisable to discontinue use and contact the supplier for evaluation.
