Description

Sodium Copper Chlorophyllin Powder Supplier:

Guanjie is a Sodium copper chlorophyllin bulk powder supplier. It refers to sodium copper chlorophyll as the dark green powder and it extracts from silkworm excrement, clover, alfalfa, bamboo's leaves. We use acetone, methanol, ethanol and petroleum ether and other organic solvent extraction. Magnesium ions is at the center of the copper ions replace the chlorophyll. At same time, with alkali saponification, the carboxyl group formed after removing the methyl and phytol groups becomes a disodium salt. Thus, copper sodium chlorophyll is a semi-synthetic pigment. And our technological process is as following. If you are interested in our producs, please feel free to contact us:info@gybiotech.com

Sodium Copper Chlorophyllin bulk Powder

Products Introduction:

It has the color of natural green plants, strong coloring power, stable to light and heat, but good stability in solid food, precipitated in the solution of PH<6, this product is more suitable for neutral or alkaline food.

Technological process

Raw material → pretreatment → leaching → filtration → saponification → ethanol recovery → petroleum ether washing → acidified copper generation → pumping filtration and water washing → dissolved into salt → filtration → drying → finished product

Preparation Technology

● The chlorophyll rich raw materials are dried at 40~ 50 e and ground into powder sodium copper chlorophyllin powder. The mixture of ethanol-acetone (1/1) with 3 times the powder content was extracted at 40~45 e for 2.5h. And the filter residue was extracted again with the same volume of ethanol-acetone mixture. We combine two extracts and add NaOH to adjust pH value to 11. Heat saponification (about 50 degrees) for 30min.

● Whether saponification is complete can be judged by petroleum ether extraction, the upper liquid yellow is complete saponification. After saponification is complete, distillate and concentrate the recovery mixture (about 60 degrees) until the volume is 1/4~ 1/3 of the original.

● Then petroleum ether was extracted 4 times. The lower layer was adjusted to the pH value of 7 with hydrochloric acid, and adjusted to the pH value of 2 with copper sulfate, and 2h with copper at 50 degrees.

● At the end of the reaction, the existing granular precipitates are formed and left to cool. The precipitation was collected at room temperature and washed with 50~ 60 ℃ water and then with 30% ~ 40% ethanol until the ethanol layer was light green.

● Then wash with petroleum ether until petroleum ether layer is light green. The cake was dissolved in acetone and precipitated with 5% NaOH ethanol solution at pH 12. The precipitates were collected and the prepared product was washed with anhydrous ethanol.

● During the preparation process, the reaction temperature is not too high, and the pH value should be adjusted carefully. Too high temperature and too large or too small pH value can decompose chlorophyll.

Main Application

● Textiles

It can dye green natural dye less, and chlorophyll copper sodium salt is a kind of food grade green color pigment, is a natural chlorophyll derivatives, can be extracted after saponification, copper reaction, and refined, is a kind of metal porphyrin with high stability, dark green powder, slightly metallic luster.

● Cosmetic

It can be added to cosmetics as dye. Sodium copper chlorophyll salt is dark green powder, odorless or slightly smelly. The water solution is transparent green, deepening with the increase of concentration, light resistance, heat resistance, good stability. The pH of 1% solution is 9.5~10.2. When the pH is below 6.5, calcium can be precipitated. Slightly soluble in ethanol. Acid drinks are easy to precipitate. Light resistance is stronger than chlorophyll, heating to 110℃ above decomposition. Due to its stability and low toxicity, sodium copper chlorophyll is widely used in cosmetics industry.

● Medical application

Because sodium copper chlorophyllin powder has no toxic side effects has a bright future IIn the medical field. A paste made of sodium copper chlorophyll accelerates healing when treating wounds. In daily life and clinical use as air freshener, especially anti-tumor research is particularly prominent.
