A natural, bright red dye obtained from the body of the female insects ''Dactylopius coccus'' Costa (formerly ''Coccus cacti'') that live on nopal cactus (''Cactus oputia'' or ''C. coccinilifera'') in Mexico, the Canary Islands, and in Central and South America. Cochineal was imported to Europe as early as 1540 where it quickly replaced kermes as the primary red dyestuff. The insects are collected from the cacti, then killed and dried in the sun or in an oven. The dye is extracted from dried insects using water or alcohol. It contains about 10% [[carminic acid]], 2% coccerin wax and 10% fat. The colorant was usually used as either a red solution or precipitated to make [[carmine lake|carmine]], an aluminum or aluminum-tin lake. Cochineal produces a transparent lake pigment that has poor lightfastness and fades in strong sunlight. | A natural, bright red dye obtained from the body of the female insects ''Dactylopius coccus'' Costa (formerly ''Coccus cacti'') that live on nopal cactus (''Cactus oputia'' or ''C. coccinilifera'') in Mexico, the Canary Islands, and in Central and South America.

Description
A natural, bright red dye obtained from the body of the female insects Dactylopius coccus Costa (formerly Coccus cacti) that live on nopal cactus (Cactus oputia or C. coccinilifera) in Mexico, the Canary Islands, and in Central and South America. Cochineal was imported to Europe as early as 1540 where it quickly replaced kermes as the primary red dyestuff. The insects are collected from the cacti, then killed and dried in the sun or in an oven. The dye is extracted from dried insects using water or alcohol. It contains about 10% Carminic acid, 2% coccerin wax and 10% fat. The colorant was usually used as either a red solution or precipitated to make carmine, an aluminum or aluminum-tin lake. Cochineal produces a transparent lake pigment that has poor lightfastness and fades in strong sunlight.
