Thousands of Carmine insects and then crush them.
Depending on the conditions in which the insects are crushed, the color of the dye can vary considerably, and this is an important consideration for companies that want to make consistent dyes.
The crushing causes the insects to release carminic acid, a substance which they generate to repel predators, and this can be treated to yield carmine.
Pure carmine is red and very crumbly.

Carmine imparts a red color to cosmetics and personal care products.
Carmine, crimson lake, natural red 5 or CI 75470 is a bright red pigment that is used in many cosmetics and even as a colourant in food.
Chemical Properties of Carmine:
Carmine is a red coloring material from the dried bodies of the female insect Coccus cacti and harvested from cultivated cacti.
The raw material is obtained primarily from the Canary Islands and parts of South America.
Boiling Carmine with mineral acid produces carmine red (ClH12O7).
Precipitating a mixture of Carmine and alum produces a bright red pigment.
Carmine is used as a color additive in food, drugs and cosmetics.
Carmine is also used as a microscopic stain and biological marker.
Preparation of Carmine:
The preparation of carmine always consists of two steps.
The dried insects are first boiled in water in order to extract the carminic or kermesic acid.
The second step is the precipitation of the pigment by adding alum to the clear filtered solution.
Aluminum ions contained in alum form a complex salt of the intense crimson-red colour.
Carmine, a red dyestuff extracted from the dried bodies of certain female scale insects native to tropical and subtropical America.
Carmine was used extensively for watercolors and fine coach-body colors before the advent of synthetic coloring materials.
Since then Carmine 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.
The purity of color 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.
Carmine is a bright red dye commonly used to color food and cosmetics.
When purchasing any sort of red or pink makeup, vegans should check the ingredients for carmine.
Carmine is made by boiling and grinding up beetles, and is therefore not vegan.
Some people argue that insects are not sentient.
But all insects have brains and relatively complex nervous systems, so they therefore possess at least some ability to suffer.
Carmine beetles are native to desert environments and were historically gathered from prickly pear cactus.
Carmine Carminewas among the first pigments used to dye clothing, and archaeologists have recovered these garments from neolithic sites.
Fortunately, few textiles use carmine anymore, since modern dyes are cheaper and much more colorfast.
About 20 percent of a Carmine beetle’s body weight is carminic acid, the pigment that gives carmine its deep red hue.
Since Carmine beetles are just a half-centimeter long, a large number must be killed to create a small amount of dye.
Production of Carmine:
The pigment is produced from carminic acid, which is extracted from some scale insects such as the Carmine scale (Dactylopius coccus), and certain Porphyrophora species (Armenian Carmine and Polish Carmine).
Carmine is a colorant used in the manufacture of artificial flowers, paints, crimson ink, rouge and other cosmetics, and some medications.
To prepare carmine, the powdered scale insect bodies are boiled in an ammonia or sodium carbonate solution.
After separating the insoluble matter, the extract is treated with alum to precipitate the red solid.
This precipitate is called "carmine lake" or "crimson lake".
Purity of color is ensured by the absence of iron.
Stannous chloride, citric acid, borax, or gelatin may be added to modify the precipitation.
The traditional crimson color is affected not only by carminic acid but also by choice of its chelating metal salt ion.
For shades of purple, lime is added to the alum.
Etymology of Carmine:
The English word "carmine" is derived from the French word carmin (12th century), from Medieval Latin carminium, from Persian قرمز qirmiz ("crimson"), which itself derives from Middle Persian carmir ("red, crimson").
The Persian term carmir is likely cognate with Sanskrit krimiga ("insect-produced"), from krmi ("worm, insect").
The Persian word for "worm, insect" is kirm, and in Iran (Persia) the red colorant carmine was extracted from the bodies of dead female insects such as Kermes vermilio and Carmine.
The form of the term may also have been influenced in Latin by minium ("red lead, cinnabar"), said to be of Iberian origin.
The word "carmine" has been used as a color name as early as 1799.
Carmine is a popular food color, used in yogurt, candy and certain brands of juice, the most notable ones being those of the ruby-red variety.
