Cochineal

Cochineal refers to a red natural transparent lake colorant that has poor lightfastness and fades in strong sunlight, yet adheres extremely well and vibrantly to protein fibers of camelid and sheep. It is prepared from the bodies of the female scale insect, Dactylopius coccus, which lives as a parasitic on the prickly-pear cactus native to Mexico, the Canary Islands, and Central and South America. Cochineal dye was used by indigenous populations throughout the Americas, and was later adopted by Europeans who used comparative lac dye prior to the Spanish Conquest in the 16th century. The pigments are extracted from the dried bodies of insects using water or alcohol. The substance contains about 10% carminic acid, 2% coccerin wax, and 10% fat: the crimson color of cochineal dye is attributed to cochinealin, or carminic acid. Cochineal is also used in medicine as an antispasmodic.
