Product description

Sodium Copper Chlorophyllin, also called chlorophyll copper sodium salt, is described as a metal porphyrin color with a dark-green powder appearance, strong tinting and a bright color. Its solution has a clear, transparent blue-green shade.

The original source describes extraction from spinach or silkworm material using acetone or ethanol, with copper sulfate added to replace the magnesium atoms in the chlorophyll porphyrin ring with copper. The specific supplied raw-material route should be confirmed for the product selected.

Compatibility and handling

The source specifically notes precipitation in the presence of calcium ions. It also states that solutions can precipitate below pH 6, attributing this to molecular aggregation under acidic conditions. These limitations belong alongside the color’s general description of high stability.

The numbered specification lists a liquid form with color value E20-E568, while the descriptive text also refers to dark-green powder.

Applications

Food products, health products, cosmetics and pharmaceutical products are listed application areas.
