Tattoo Ink & Safety Guide

What Is Tattoo Ink Made Of?

Tattoo ink is a suspension of pigment particles in a liquid carrier. The pigment provides colour; the carrier keeps it evenly distributed and helps deliver it into the skin.

Pigments

Pigments are the colouring agents in tattoo ink. They can be:

• Organic (carbon-based) — derived from plants, animals, or synthesised chemically. Most modern colour inks use synthetic organic pigments.
• Inorganic (mineral-based) — metal salts and oxides such as titanium dioxide (white), iron oxides (red/brown/black), and carbon black.

The same pigments are used in printing inks, cosmetics, and industrial paints — tattoo ink is not a uniquely regulated product category in most countries, which is part of why safety regulations have lagged behind.

Carrier Solutions

Carriers keep pigment particles suspended and help the ink flow smoothly. Common carrier ingredients include:

• Distilled water
• Ethyl alcohol or isopropyl alcohol
• Glycerin (may be animal- or plant-derived)
• Witch hazel
• Propylene glycol

Some inks include additional ingredients such as preservatives, surfactants, or stabilisers. Reputable manufacturers publish full ingredient lists; avoid inks with undisclosed formulations.

Types of Tattoo Ink

Common Allergens & Safety Concerns

Allergic reactions to tattoo ink are uncommon but do occur. Most reactions are delayed — appearing weeks, months, or even years after the tattoo was applied.

High-Risk Pigments

• Red pigments — Mercury sulphide (cinnabar) was historically a common allergen and is now largely discontinued. Modern red pigments (azo-based) still carry a higher reaction rate than other colours.
• Yellow pigments — Certain azo dyes in yellow inks can cause photosensitivity reactions, especially in sun-exposed areas.
• Carbon black — The EU has flagged some carbon black pigments for containing polycyclic aromatic hydrocarbons (PAHs), which are potentially carcinogenic.

Reaction Types

• Allergic contact dermatitis — Redness, swelling, and itching localised to the tattooed area.
• Photosensitivity — Reaction triggered by UV light exposure, common with yellow and red pigments.
• Granuloma — Small bumps that form when the immune system reacts to pigment particles as foreign bodies.
• MRI interference — Rare cases of discomfort or burns during MRI scans have been reported with tattoos containing metallic pigments (primarily iron oxides). This risk is very low.

Vegan Tattoo Ink

Traditional tattoo ink formulations sometimes contain animal-derived ingredients. The most common are:

• Bone char — Used in some black inks to achieve deep blacks.
• Glycerin from animal fat — Used as a carrier component.
• Shellac — A resin secreted by lac bugs, used as a binder in some inks.
• Gelatine — An animal protein occasionally used as a stabiliser.

Many modern inks are vegan by default, using plant-derived glycerin and synthetic alternatives. If veganism is important to you, ask your artist to confirm the ink brand and check the manufacturer's ingredient disclosure. Brands such as Intenze, Dynamic, and Eternal Ink offer vegan-certified product lines.

Tattoo Ink Regulations by Region

European Union

The EU has the strictest tattoo ink regulations in the world. Under the REACH regulation, the European Chemicals Agency (ECHA) published new restrictions on tattoo ink ingredients that took effect in January 2022 and January 2023.

Key restrictions include:

• Ban on over 4,000 harmful substances in tattoo inks and permanent make-up.
• Restrictions on azo dyes that can release carcinogenic aromatic amines.
• Limits on polycyclic aromatic hydrocarbons (PAHs) in carbon black pigments.
• Restrictions on certain blue and green pigments (PB15, PG7) — though these have faced pushback from the tattoo industry due to a lack of proven alternatives.

Many inks sold in Europe have been reformulated to comply. If you're an EU-based artist, verify that your ink supplier is REACH-compliant.

United States

In the US, tattoo ink is regulated by the FDA as a cosmetic product. However, the FDA does not pre-approve tattoo inks before they go to market. Oversight is largely reactive — the FDA investigates complaints and can issue recalls for contaminated inks.

Notable FDA actions include recalls of inks found to be contaminated with Mycobacterium bacteria. Contamination is more common in grey-wash inks that are mixed with distilled water by the artist.

There is currently no federal US law requiring tattoo ink manufacturers to disclose a full ingredient list.

United Kingdom

Post-Brexit, the UK retained EU REACH regulations as UK REACH. Similar restrictions on tattoo ink ingredients apply, with enforcement managed by the Health and Safety Executive (HSE).

Australia

Tattoo ink in Australia falls under the jurisdiction of the Therapeutic Goods Administration (TGA). The TGA has issued guidance on prohibited substances but does not formally license tattoo inks before sale.

Rest of World

Most other countries have limited or no specific regulations governing tattoo ink composition. Artists in unregulated markets are encouraged to use inks from reputable international brands that voluntarily comply with EU REACH standards as a benchmark.

How to Choose a Safe Tattoo Studio

Ink quality is only one part of tattoo safety. The studio environment and artist practices matter just as much. Look for:
