What is in Tattoo ink?

I've decided to start doing some more informational blogs on here. If you are interested in more of the science behind tattooing, please visit: www.thescienceoftattooing.com

Tattoo ink is made up of two main components: pigments and carrier fluids.

1. Pigments (Color)

• These are the substances that give the ink its color. They can come from a variety of sources:

  • Carbon black (for black ink)

  • Metallic salts (like iron oxide or titanium dioxide for red and white)

  • Organic compounds (such as azo dyes for bright colors)

  • Plastic-based pigments (used for vibrant, long-lasting colors)

2. Carrier Fluids

• These are liquids that help evenly distribute the pigment and prevent contamination. Common carriers include:

  • Distilled water

  • Glycerin

  • Alcohol (like ethanol or isopropyl alcohol)

  • Propylene glycol

  • Witch hazel

3. Other Additives

• Some inks may also contain:

  • Preservatives

  • Binding agents

  • Thickeners or stabilizers
