Our Sodium Copper Chlorophyllin fine powder is a dark green to blackish-green fine powder refined from chlorophyll extracted from natural silkworm excrement or alfalfa through semi-synthetic processes such as copperization, saponification, and salt formation. It has a slightly distinctive odor.
Each batch of product undergoes rigorous testing for total copper content, free copper, absorbance (E1cm1% around 405nm), lead, arsenic, mercury, and microbiological indicators to ensure stable copper complexation and that free copper is controlled within international limits. Test reports conforming to GB 1886.11 or FCC standards are available. This product is primarily suitable for food and health product coatings, solid beverages, candies, toothpaste, and some water-based cosmetic formulations requiring a bright green hue, serving as a natural source of green colorant.

Benefits of Sodium Copper Chlorophyllin fine powder
Natural Green Coloring: Provides a stable, brilliant green hue to foods, beverages, and oral care products without the use of synthetic dyes such as FD&C Green No. 3.
Odor Masking Properties: Possesses a natural chlorophyll character that can help mask unpleasant odors or aftertastes in plant-based proteins, nutritional supplements, and functional foods.
Heavy Metal Binding Support: The porphyrin ring structure of chlorophyllin has been studied for its ability to bind with certain environmental toxins and support natural elimination pathways.
Oral Care Benefits: Demonstrates deodorizing properties that help reduce oral malodor when incorporated into mouthwashes, lozenges, and toothpaste formulations.
Digestive Comfort Support: May contribute to maintaining digestive tract comfort and regularity as part of a balanced nutritional regimen.
Antioxidant Support: Acts as a free radical scavenger, helping to protect formulations and, when consumed, supporting the body's natural antioxidant defense systems.
Non-Bleeding Property: Does not migrate or bleed between phases in multi-layered or multi-colored products, an advantage over some synthetic and natural colorants.
Application Fields
Food & Beverage Coloring
It as a natural green colorant (E141(ii)) in candies, confectionery, ice cream, desserts, powdered drink mixes, and carbonated beverages.
Pharmaceutical Coatings
Incorporate it into tablet film coatings and capsule shells to provide a stable green color that does not bleed.
Cosmetic Formulations
Add it to toothpaste, mouthwash, soaps, shampoos, and skin care products for green color and its chlorophyll character.
Oral Care Products
Use it in mouthwashes, lozenges, and breath freshener products as a natural green coloring agent.
Pet Food & Treats
Add it to dry kibble, wet food, and dental chews for color enhancement.
Textile & Industrial Dyes
Use it as a dye for natural fibers, soaps, and candles where water-soluble green color is required.
Production Process

FAQ
Q: Is Sodium Copper Chlorophyllin natural?
A: It is a semi-synthetic derivative of natural chlorophyll. The starting material is natural chlorophyll extracted from plants, which is then chemically modified to replace magnesium with copper and convert it to a water soluble sodium salt.
Q: What is the difference between Chlorophyll and Sodium Copper Chlorophyllin?
A: Natural chlorophyll is oil-soluble, unstable to heat and light, and has a very low shelf life. Sodium copper chlorophyllin is water-soluble, highly stable, and resistant to discoloration. Additionally, the copper center is more stable than magnesium, allowing for prolonged storage and processing.
Q: Does Sodium Copper Chlorophyllin fine powder provide dietary copper?
A: The copper in chlorophyllin is tightly bound to the porphyrin ring and is not released in the digestive tract like ionic copper. It is not intended as a copper supplement, and absorption is minimal. The copper content is strictly regulated and safe at recommended intake levels.
Q: Does it stain teeth or skin?
A: When used in oral care products at appropriate concentrations, it does not permanently stain teeth. However, highly concentrated solutions may temporarily color the tongue or teeth green, which is easily brushed away. In supplements, it may transiently discolor urine green.
Q: Is this product sensitive to pH?
A: Yes. The green color is stable at pH 6–11. Below pH 6, it may precipitate or change hue . Avoid acidic formulations.
