Tattoo ink can contain animal-derived ingredients at nearly every stage of its production, from the pigments that give it color to the carriers that keep those pigments in suspension, to the binders that help ink stay put in skin. Some of the most common offenders are bone char in black inks, shellac as a binding agent, and glycerin sourced from animal fat. What makes the issue especially tricky for vegans is that many of these ingredients go unlisted on the bottle, and the tattoo industry has historically faced little regulatory pressure to disclose them.
Animal-Derived Pigments Hide in Plain Sight
The most fundamental layer of the problem is the pigment itself. Black ink, the workhorse of tattooing, sometimes gets its deep color from bone char, which is exactly what it sounds like: animal bones heated to extreme temperatures until they become a fine carbon powder. Bone char has been used as a black pigment for centuries across many art forms, and some tattoo ink manufacturers still use it because it produces a rich, stable black. Synthetic carbon black, made from soot or petroleum byproducts, works just as well and has largely replaced bone char in modern formulations, but “largely” is not “entirely.” Without explicit labeling, there is no way to know which source of carbon black is in a given bottle.
Red inks carry their own animal-derived risk. Carmine, a vivid red pigment extracted from crushed cochineal insects, has been a staple of the dye industry for centuries. It takes tens of thousands of these small beetles to produce a kilogram of carmine. While synthetic red pigments now dominate the tattoo ink market, carmine still shows up in some formulations, particularly those marketed as using “natural” colorants. The word “natural” on a tattoo ink label tells you almost nothing about whether animals were involved.
Binders and Carriers Are Where It Gets Sneaky
Pigment is only part of what goes into a bottle of tattoo ink. The pigment needs to be suspended in a liquid carrier so that it flows through a tattoo machine and deposits evenly into skin. It also needs binders and stabilizers to keep the pigment from clumping or separating over time. Several of the substances used for these jobs come from animals.
Shellac is one of the less obvious culprits. It is a resin secreted by the lac insect, harvested from tree bark in South and Southeast Asia, and used widely in food glazes, pharmaceutical coatings, and cosmetics. In tattooing, shellac has been used as a binding agent in certain ink formulations. A documented case of allergic contact dermatitis traced to shellac in a black tattoo ink confirmed that the substance does appear in commercial products, even though many consumers would never think to look for insect-derived resin in their tattoo ink.1PubMed Central.

Glycerin is probably the most widespread animal-derived ingredient in tattoo ink. It serves as a humectant and carrier, helping the ink maintain a smooth consistency. Glycerin can be derived from either plant oils or animal fats, and both versions are chemically identical. The issue is that animal-derived glycerin is often cheaper to produce, so unless a manufacturer specifically sources plant-based glycerin and says so, there is no way to tell from the ingredient list alone. Many ink brands that do not market themselves as vegan default to whichever glycerin their supplier offers at the best price.
Gelatin, derived from the collagen in animal skin and bones, occasionally appears as a stabilizing or thickening agent. It is less common in modern tattoo inks than glycerin or shellac, but it has not disappeared entirely. Some traditional ink recipes also call for beeswax as a thickener, though this is more typical of handpoke or traditional tattooing methods than of machine tattooing.
What the Label Does Not Tell You
Even if you read every word on a bottle of tattoo ink, you may not get the full picture. A 2024 analysis of 54 commercial tattoo inks sold in the United States found that 45 of them contained additives or pigments not listed on the label.2American Chemical Society (ACS Publications). What’s in my ink: an analysis of commercial tattoo ink on the US market The most common unlisted additive was polyethylene glycol (PEG), found in 28 of the 54 inks. Fifteen inks contained unlisted propylene glycol. Seven contained higher alkanes, compounds that researchers noted had not previously been documented in the tattoo ink literature. One red ink’s residue, when extracted and analyzed, turned out to be consistent with dodecane, a hydrocarbon not typically associated with tattoo products at all.2American Chemical Society (ACS Publications). What’s in my ink: an analysis of commercial tattoo ink on the US market
None of these particular unlisted substances are animal-derived, but the finding matters for vegans because it reveals how unreliable tattoo ink labeling is in general. If a manufacturer is not listing the polyethylene glycol in its ink, there is no special reason to trust that it is listing its glycerin source, its binder ingredients, or the origin of its pigments. The tattoo ink industry in the United States is not subject to the same pre-market ingredient disclosure requirements that apply to food or pharmaceuticals. The FDA classifies tattoo inks as cosmetics but has historically not exercised the same level of oversight over them that it does over products like sunscreen or hair dye.
This regulatory gap means that “vegan” claims on tattoo ink are largely self-certified by the manufacturer. There is no standard third-party vegan certification body that dominates the tattoo ink market the way that, say, the Leaping Bunny program certifies cruelty-free cosmetics. Some brands pursue certification through organizations like The Vegan Society or PETA’s “Beauty Without Bunnies” program, but many simply print “vegan” on the label without external verification.
Animal Testing Is the Other Half of the Equation
For many vegans, the question is not only whether a product contains animal ingredients but also whether animals were harmed in developing or testing it. Tattoo ink occupies an uncomfortable space here. While most tattoo ink companies do not conduct animal testing themselves, the pigments they use were often first evaluated for safety in animal models by other parties, particularly by the chemical suppliers who manufacture the raw pigments for multiple industries.
Research into the biological effects of tattoo pigments has relied on animal models. One study tattooed hairless mice with commercial inks and tracked the skin’s inflammatory response over 14 days. The mice developed dermal hemorrhage within half a day, followed by acute inflammation, tissue death in the outer skin layer, and chronic inflammation that persisted through the end of the observation period. Pigment migrated to the inguinal and axillary lymph nodes, where it triggered immune reactions including lymphoid hyperplasia.3PubMed. Response of mouse skin to tattooing: use of SKH-1 mice as a surrogate model for human tattooing The researchers concluded that the mouse response closely resembled the acute injury seen in tattooed human skin, suggesting that mice could serve as a surrogate model for studying the safety of tattoo ink ingredients going forward.
More recent work has used amphibian and other non-mammalian models to evaluate tattoo pigment toxicity. One study exposed frog embryos to a red azo pigment (PR170) commonly found in tattoo inks and observed deformed embryos, oxidative stress, and changes in the expression of genes involved in development and inflammation.4PubMed Central. Comparative Toxicological Evaluation of Tattoo Inks on Two Model Organisms These toxicological studies are not commissioned by tattoo parlors or ink brands; they are conducted by academic researchers and regulatory bodies trying to understand whether the chemicals in ink are safe for the millions of people getting tattoos. But they do involve animals, and a strict vegan framework holds that products whose safety was established through animal testing are not truly cruelty-free.
This creates a philosophical gray area. If a tattoo ink brand has never tested on animals and does not use animal-derived ingredients, but the synthetic pigments it buys were originally safety-tested on mice by the chemical manufacturer decades ago, is the ink vegan? Different people draw the line in different places. Some focus on what is practically avoidable: choosing a brand that does not commission new animal testing and does not use animal-derived ingredients. Others adopt a stricter stance and try to trace the full supply chain, though this is nearly impossible in practice.
How to Actually Find Vegan Tattoo Ink
If you are planning a tattoo and want to avoid animal-derived ingredients and animal testing as much as possible, the conversation starts with your tattoo artist, not with the ink manufacturer’s website. Most professional tattoo artists work with a small number of ink brands they trust, and a good artist will be able to tell you exactly which brand and color line they use. From there, you can check the manufacturer’s claims.
A few things to look for and ask about:
- Glycerin source: Ask whether the ink uses vegetable glycerin rather than animal-derived glycerin. Brands that market themselves as vegan will specify this.
- Pigment origin: Look for inks that use synthetic pigments rather than bone char or carmine. Most modern professional-grade inks already do, but confirmation matters.
- Binder ingredients: Ask whether shellac, gelatin, or beeswax appear in the formulation. Vegan inks typically use synthetic polymers or plant-derived binders instead.
- Third-party certification: A vegan certification from an established organization carries more weight than a self-applied label. It does not guarantee perfection, but it means someone outside the company reviewed the ingredient list.
- Animal testing policy: Look for a clear statement that the company does not test on animals and does not commission animal testing through third parties.
Several ink brands now market specifically to vegan consumers. These companies typically reformulate traditional recipes to replace animal-derived carriers and binders with synthetic or plant-based alternatives. The color performance and longevity of vegan inks have improved substantially over the past decade, and many professional tattoo artists report no meaningful difference in how vegan inks handle compared to conventional ones.
Aftercare Products and the Bigger Blind Spot
People who go to the trouble of finding vegan tattoo ink sometimes overlook the aftercare. The ointments, balms, and moisturizers you apply to a fresh tattoo during healing are just as likely to contain animal-derived ingredients as the ink itself. Lanolin, a waxy substance derived from sheep’s wool, is one of the most common ingredients in traditional tattoo aftercare balms. Beeswax shows up frequently in healing salves. Some petroleum-based aftercare products are vegan by composition but may have been tested on animals at some point in their development.
Transfer paper and stencil products are another overlooked category. The transfer solution or stencil primer that your artist applies before tattooing can contain animal-derived ingredients, though this varies widely by brand. Even the soap used to clean the skin before and during tattooing may contain tallow, an animal fat. If the goal is a fully vegan tattoo experience from start to finish, it is worth discussing every product that will touch your skin, not just the ink.
Why Ingredient Transparency Remains So Poor
Compared to food, pharmaceuticals, or even conventional cosmetics, tattoo ink labeling is remarkably loose. In the United States, the FDA has authority to regulate tattoo inks as cosmetics but has traditionally devoted few resources to enforcement. The agency has issued warnings and recalls for contaminated inks and has investigated specific color additives, but it does not require pre-market approval of tattoo ink formulations. Manufacturers are technically required to list ingredients, but the 2024 analysis showing that more than 80 percent of tested inks contained unlisted additives suggests that compliance is uneven at best.2American Chemical Society (ACS Publications). What’s in my ink: an analysis of commercial tattoo ink on the US market
The European Union has taken a more aggressive approach. In 2022, the EU’s REACH regulation restricted or banned thousands of chemicals in tattoo inks, including certain pigments and preservatives linked to health risks. These restrictions forced many ink manufacturers to reformulate, and some reformulations incidentally made inks more vegan-friendly by replacing traditional animal-derived binders with synthetic alternatives. But the EU regulations were designed to address toxicity, not animal welfare, so they do not require vegan labeling or animal-derived ingredient disclosure as a separate category.
The net result is that vegans looking for tattoo ink operate in an environment where even the basic ingredient list is unreliable. The most practical path forward is to choose brands that have made vegan formulation a deliberate part of their identity, verify their claims through third-party certification where possible, and accept that some degree of uncertainty is baked into a market where ingredient transparency is still catching up to consumer expectations.
Stencil Ink, Numbing Creams, and Other Peripheral Products
Beyond the tattoo ink itself and the aftercare ointments, a full tattoo session involves several other products that may contain animal derivatives. Numbing creams, increasingly popular for painful placements like ribs or inner arms, often contain emulsifiers or stabilizers sourced from animal fats. Lidocaine-based numbing agents are generally synthetic in their active ingredient, but the cream base can include lanolin, stearic acid from tallow, or other animal-derived emollients.
Disposable supplies like nitrile gloves are typically vegan, but latex gloves sometimes use casein, a milk protein, in their manufacturing process. Razors used for pre-tattoo shaving may have lubrication strips containing animal-derived ingredients like glycerin or lanolin. These are small details, but they illustrate how deeply animal products are embedded in everyday manufacturing. A tattoo artist who understands your preferences can often accommodate vegan-friendly alternatives across the full range of products used during a session, provided you raise the question in advance rather than in the chair.
