Carmine (/ ˈ k ɑːr m ə n, ˈ k ɑːr m aɪ n /) – also called cochineal (when it is extracted from the cochineal insect), cochineal extract, crimson lake, or carmine lake – is a pigment of a bright-red color obtained from the aluminium complex derived from carminic acid. [1] Specific code names for the pigment include natural red 4, C.I ...
The two principal forms of cochineal dye are cochineal extract, a coloring made from the raw dried and pulverised bodies of insects, and carmine, a more purified coloring made from the cochineal. To prepare carmine, the powdered insect bodies are boiled in ammonia or a sodium carbonate solution, the insoluble matter is removed by filtering, and ...
An aluminum salt of carminic acid is the coloring agent in carmine, a pigment. [4] Natives of Peru had been producing cochineal dyes for textiles since at least 700 CE. [4] Synonyms are C.I. 75470 and C.I. Natural Red 4. [5] The chemical structure of carminic acid consists of a core anthraquinone structure linked to a glucose sugar unit.

Strong red colors for eye products have been produced using the dye carmine, made from carminic acid extracted from the crushed bodies of the cochineal insect. [6] Carmine was once the only bright red color permitted by the FDA for use around the eye.

Kermesic acid is an anthraquinone derivative and the main component of the red dye kermes (false carmine). The compound is the aglycone of carminic acid, the main component of true carmine. As a dye, it is known as Natural Red 3. Kermesic acid, like carminic acid and the laccaic acids, is an insect dye obtained from scale insects.
