* * *

      red or purplish-red pigment obtained from cochineal (q.v.), a red dyestuff extracted from the dried bodies of certain female scale insects native to tropical and subtropical America. Carmine was used extensively for watercolours and fine coach-body colours before the advent of synthetic colouring materials. Since then it has been used only when a natural pigment is required: for pastries, confections, cosmetics, water-soluble drug preparations, and histologic stains.

      To prepare carmine, the powdered insect bodies are boiled in ammonia or sodium carbonate solution, the insoluble matter is removed by filtering, and alum is added to the clear salt solution of carminic acid to precipitate the red aluminum salt. Purity of colour is ensured by the absence of iron. Stannous chloride, citric acid, borax, or gelatin may be added to regulate the formation of the precipitate. For purple shades, lime is added to the alum. Chemically, carminic acid is a complex anthraquinone derivative.
