The ink tattoo consists of pigments combined with the carrier, and is used in tattoos.
Tattoo inks are available in various colors that can be thinned or mixed together to produce other colors and shades. Most professional tattoo artists buy pre-made inks (known as pre-scattered inks), while some tattoos mix themselves using dry pigments and carriers.
The tattoo ink is generally permanent. Tattoo removal is difficult, painful, and the success rate depends on the material used. The recently claimed ink is relatively easy to remove. Unfounded claims have been made that some ink fades over time, resulting in "semi-permanent tattoos."

Rule
In the United States, tattoo inks are subject to regulation by the US Food and Drug Administration as cosmetics and color additives. However, these regulatory authorities are generally not implemented. FDA and medical practitioners have noted that many of the ink pigments used in tattoos are "the color of industrial power suitable for printer ink or car paint."
In California, Proposition 65 requires that Californians be warned before exposure to certain harmful chemicals; tattoo salons in California should warn their customers that tattoo inks contain heavy metals that are known to cause cancer, birth defects, and other reproductive hazards.

Pigment base
Manufacturers are not required to disclose their materials or conduct trials, and recipes may be exclusive. Professional inks can be made from iron oxide (rust), metal salts, or plastics. Homemade or traditional tattoo ink can be made from pen ink, soot, dirt, blood, or other ingredients.
Heavy metals used for color include mercury (red); tin (yellow, green, white); cadmium (red, orange, yellow); nickel (black); zinc (yellow, white); chromium (green); cobalt (blue); aluminum (green, purple); titanium (white); copper (blue, green); iron (brown, red, black); and barium (white). Metal oxides used include ferrocyanide and ferricyanide (yellow, red, green, blue). Organic chemicals used include azo-chemical (orange, brown, yellow, green, purple) and chemicals derived from naphtha (red). Carbon (soot or ash) is also used for black. Other elements used as pigments include antimony, arsenic, beryllium, calcium, lithium, selenium, and sulfur.
Tattoo tattoo manufacturers typically incorporate heavy metal pigments and/or use lightening agents (such as lead or titanium) to reduce production costs.
Operator
A carrier acts as a solvent for the pigment, to "carry" the pigment from the point of the trauma needle to the surrounding dermis. Operators keep the ink well-mixed and free of pathogens, and aid applications. The most common solvents are ethyl alcohol or distilled water, but denatured alcohols, methanol, rubbing alcohols, propylene glycol, and glycerol are also used. When alcohol is used as part of the tattoo ink carrier base or to disinfect the skin prior to tattoo application, it enhances skin permeability, helping to transport more pigments to the skin.
Health issues
Medical problems, though rare, can be caused by tattoos.
Medical workers have observed the rare but severe medical complications of tattoo pigments in the body, and have noted that people who get tattoos rarely assess previous health risks to receive their tattoos.
Recent case reports also show that tattoo pigments migrate to lymph nodes. This can appear in some types of medical scanning as a tumor. A woman was given a complete hysterectomy only to find out later that the lymph nodes contain pigment tattoos.
Other tattoo inks
Shines in dark ink and black ink
Both blacklight and glow in the dark ink have been used for tattoos. Light in dark ink absorbs and retains light, and then shines in dark conditions by a fluorescent process. Blacklight ink does not glow in the dark, but reacts to invisible UV rays, producing visible light by fluorescence. The light generated from these two inks varies greatly.
The security of the ink for use in humans is widely debated in the tattoo community.
Materials in some "light" inks are listed as: (PMMA) Polymethylmethacrylate 97.5% and 2.5% fluorescent dye microspheres suspended in UV sterilized, distilled water.
Removable tattoo ink
While ink tattoos are generally very painful and difficult to remove, tattoo removal is fairly involved, the recently introduced inks have been developed to be more easily removed with laser treatment than traditional ink.
black henna
Health Canada has advised against using "black henna" tattoo tattoos containing para-phenylenediamine (PPD), a hair dye. Black Henna is usually applied externally in Mehandi's temporary application, rather than being put under the skin in a permanent tattoo.
Other inks can be used instead of black henna. "Jagua", fruit-based ink proved to be a healthier alternative for black girlfriends.
Allergic reactions to PPD include rash, contact dermatitis, itching, blisters, open wounds, scarring and other harmful effects.
Vegan tattoo inks
Various tattoo ink manufacturers also produce vegan-friendly inks that do not contain animal by-products such as bone char, glycerin, gelatin and lacquers.
Ancient Roman Recipe
Roman doctor Aetius made a recipe for tattoo ink:
A pound of Egyptian pine bark
Two ounces of bronze are corroded, ground with vinegar
Two ounces of bile (bile from the gallbladder)
An ounce of vitriol (iron sulfate)
Stir well and strain. Soak powder in 2 parts water and 1 leek. Wash skin for tattooing with leek juice. Puncture the design with the needle until the blood is taken. Rub in ink.
