Quick answer: Paint is not vegan when it contains animal-derived ingredients or was tested on animals. The usual culprits are ox gall (a wetting agent in watercolor), honey, gelatin or egg used as binders or humectants, casein from milk, beeswax, shellac from insects, carmine red made from cochineal insects, and bone black pigment made from charred animal bones. Most of these are not listed on the front of the package, so you often have to check the pigment codes or ask the manufacturer.
Paint seems like an unlikely place to find animal products. There is no meat, no leather, no obvious fur. Yet a tube of traditional watercolor can contain a bovine digestive fluid, a tube of black acrylic can contain charred bones, and the pink in a children’s face-paint kit can come from crushed insects. None of this is a secret in the industry; it is simply not printed in large type.
If you are trying to understand what makes paint not vegan, either for your own practice or because you are choosing supplies for a child in a vegan household, this guide walks through every category of animal ingredient, where it shows up, and how to check. For a shortlist of sets that have already been vetted, see our guide to the best vegan paints for kids.
What Makes Paint Not Vegan?
Paint has three basic parts: pigment (the color), binder (what holds the pigment together and sticks it to the surface) and additives (everything else, such as wetting agents, preservatives and thickeners). Animal ingredients can appear in all three. A fourth consideration, animal testing, has nothing to do with ingredients but matters to most people who follow a vegan ethic.
Animal ingredients in binders
- Gelatin: Made by boiling animal skin, bones and connective tissue. Used as a binder in some traditional glue-based paints and gesso, and as the sizing in many papers. Rabbit-skin glue, a traditional canvas size, is a form of gelatin.
- Egg: The binder in egg tempera, a historic fine-art medium, and occasionally in homemade or specialty children’s paints.
- Casein: A milk protein used as the binder in casein paint and in some older poster and school paints. Casein paint has a matte, velvety finish and is still sold for fine art and illustration.
- Honey: Added to many traditional watercolors and some gouache as a humectant that keeps the paint from drying out in the pan. Honey is an animal product under most vegan definitions.
- Beeswax: The binder in encaustic paint and an ingredient in many crayons, oil pastels and some wax-based resist media.
Animal ingredients in pigments
- Bone black (PBk9): Also sold as ivory black. Made by charring animal bones. It is one of the most common black pigments in artist acrylics, oils and watercolors. The pigment code PBk9 on a tube is a reliable indicator.
- Carmine / cochineal (NR4): A crimson dye extracted from cochineal insects. Used in some watercolors, inks and, notably, in cosmetics and face paints. Labeled as carmine, cochineal, natural red 4, CI 75470 or E120.
- Sepia: Historically made from cuttlefish ink. Modern “sepia” paints are almost always synthetic mixtures, but a few specialty makers still use the real thing.
- Indian yellow: Originally made from the urine of cows fed mango leaves. Modern versions are synthetic, but the name survives, which causes confusion.
- Pearlescent and shimmer pigments: Some use guanine from fish scales, especially in cosmetics. Most art-grade mica pigments are mineral or synthetic, but it is worth checking in glitter and metallic kids’ paints.
Animal ingredients in additives
- Ox gall: Bile from cattle, used as a surfactant in watercolor to improve flow and wetting. It is in a great many traditional watercolor formulas and is also sold as a separate medium. This is the single most common reason a watercolor set is not vegan.
- Shellac: A resin secreted by the lac insect. Used in some inks, varnishes, fixatives and as a binder in India ink and certain pigment sticks.
- Lanolin: Wool grease, occasionally found in crayons, lip-safe face paints and some wax-based art materials.
- Stearic acid and glycerin: Both can be plant- or animal-derived. They appear in crayons, pastels and watercolors. Unless the manufacturer specifies vegetable sourcing, the origin is unknown.
- Animal-hair brushes: Not paint, but often bundled with kids’ sets. Sable, squirrel, goat, hog bristle and pony hair are all animal. Synthetic brushes are the vegan alternative and are generally better for children anyway because they hold up to rough handling.
Animal testing
Even a paint with entirely plant and mineral ingredients may have been tested on animals, either by the paint company or by the supplier of a raw ingredient. This is more common in the cosmetics world than in art supplies, which is relevant for face paints and body paints marketed to children. Brands that are certified by a recognized cruelty-free program have committed to no animal testing at any stage.
Which Paint Types Are Most Likely to Contain Animal Products?
The risk varies a lot by medium. This table gives a general picture; individual brands always override it.
| Paint type | Likelihood of animal ingredients | Usual culprits |
|---|---|---|
| Watercolor (traditional) | High | Ox gall, honey, bone black, carmine |
| Gouache | Moderate to high | Honey, ox gall, bone black |
| Acrylic | Low to moderate | Bone black in some colors; occasional animal-derived additives |
| Oil paint | Moderate | Bone black, beeswax in some formulas; animal-derived stearates |
| Tempera / poster paint (kids) | Low to moderate | Casein or egg in some; undisclosed additives |
| Washable kids’ paint | Low | Usually synthetic, but rarely labeled vegan |
| Finger paint | Low to moderate | Food-based thickeners are usually plant; check for milk derivatives |
| Face paint | High | Carmine, beeswax, lanolin, animal testing |
| Crayons and oil pastels | Moderate to high | Beeswax, stearic acid, lanolin |
| Encaustic | Very high | Beeswax is the binder |
| Casein and egg tempera | Always | Milk protein or egg are the binder |
How to Check Whether a Kids’ Paint Set Is Vegan
Children’s art supplies in the US are required to carry safety labeling, but not ingredient lists, so you often have to do a little detective work. Follow these steps in order.
- Look for an explicit vegan claim. Many brands now print “vegan” on the box or list it on their website. A claim from the manufacturer is the most reliable indicator short of a third-party certification.
- Check the pigment codes if they are given. Artist-grade paints list pigment codes such as PBk9 (bone black) and NR4 (carmine). If you see either, that color is not vegan. Children’s paints rarely list codes, so this works best for student and artist lines.
- Scan for the keyword ingredients. Ox gall, honey, gelatin, casein, milk protein, egg, beeswax, shellac, lanolin, carmine, cochineal, bone char, ivory black. Any of these ends the question.
- Look at the included brushes. Natural hair brushes mean the set is not fully vegan even if the paint is. Sets with synthetic brushes are easy to find.
- Check for a cruelty-free certification. This matters most for face paints, which are regulated as cosmetics and are more likely to have been animal tested.
- Email the manufacturer. Ask two direct questions: does the product contain any animal-derived ingredients, including in additives, and is it tested on animals? Most companies answer within a few days. Vague replies about “trade secrets” usually mean the answer is not the one you want.
If that sounds like a lot of work for a paint set, it is. That is why we did the checking for the sets in our roundup of vegan-friendly paint sets for children, which lists what each brand has stated about its ingredients.
What Is Vegan Cosmetics, and Why Does It Matter for Face Paint?
The phrase “vegan cosmetics” comes up often alongside vegan paint because the two overlap in one specific product: face and body paint. In the US, anything applied to skin for color is regulated as a cosmetic, which means face paint follows cosmetic ingredient rules rather than art-material rules.
Vegan cosmetics avoid animal-derived ingredients such as carmine, beeswax, lanolin, guanine, collagen, keratin and animal-sourced glycerin or stearic acid, and they are not tested on animals. Face paints marketed for children’s parties and Halloween frequently fail on carmine (the red and pink shades) and beeswax (the base in many crayon-style face sticks). Because cosmetics in the US must list ingredients, face paint is actually easier to check than regular kids’ paint: read the ingredient panel and look for the terms above.
Vegan Alternatives for Every Animal Ingredient
None of the animal-derived ingredients in paint are irreplaceable. Manufacturers who make vegan lines substitute as follows:
- Ox gall is replaced with synthetic surfactants that lower surface tension in the same way.
- Honey is replaced with vegetable glycerin or corn syrup as a humectant.
- Gelatin sizing is replaced with synthetic or starch-based sizing in paper, and with acrylic polymer in gesso.
- Casein and egg are replaced with acrylic or PVA binders, which also make the paint more durable.
- Beeswax is replaced with soy wax, carnauba wax or paraffin in crayons and resist media.
- Bone black is replaced with carbon black (PBk7), lamp black (PBk6) or Mars black (PBk11, an iron oxide). Mars black is actually more opaque and dries faster in oils.
- Carmine is replaced with synthetic quinacridone or naphthol reds, which are also more lightfast.
- Natural hair brushes are replaced with synthetic filaments, which for kids’ use are more durable and easier to clean.
In most cases the vegan version performs as well or better. The reason animal ingredients persist is tradition and the cost of reformulating, not performance.
Common Misconceptions
“Non-toxic means vegan.” It does not. Non-toxic refers to the safety of the product if swallowed or touched, assessed under the ASTM D-4236 standard in the US. Bone black and ox gall are non-toxic and still animal-derived.
“Natural means vegan.” The opposite is often true. Many “natural” paints lean on traditional ingredients like beeswax, casein and egg precisely because they are natural. Synthetic paints are more likely to be vegan.
“Acrylic is always vegan.” The acrylic binder is synthetic, but the pigments and additives may not be. Black acrylics are the most common exception because of bone black.
“If it isn’t labeled, it’s probably fine.” Art materials are not required to list ingredients, so silence tells you nothing. Treat an unlabeled set as unknown until the manufacturer confirms.
Why This Matters More for Children’s Paint
Kids put paint on their hands, their faces and occasionally in their mouths. Parents in vegan households usually want the same standard for what goes on a child’s skin as for what goes on their plate. Children’s paint is also used in larger quantities than fine-art paint and replaced often, so the choice has a bigger cumulative effect.
The good news is that washable tempera and poster paints for kids are mostly synthetic by design, because synthetic binders wash out of clothing more easily. The uncertainty is mostly in the small details: an undisclosed additive, a bundled natural-hair brush, or a black made with bone char. A brand that states its position clearly removes that uncertainty.
FAQs
What makes paint not vegan?
Animal-derived ingredients such as ox gall in watercolor, honey or gelatin as binders or humectants, beeswax, bone black made from charred animal bones, carmine from insects, casein from milk and shellac. Animal testing also disqualifies a paint for most people who follow a vegan ethic.
Is acrylic paint vegan?
Usually, because the binder is synthetic. Some colors, especially blacks, use bone black pigment (PBk9), and a few lines use animal-derived additives, so check the individual color rather than assuming the whole range is vegan.
Is watercolor paint vegan?
Often not by default. Many traditional watercolors contain ox gall as a wetting agent and some include honey. Vegan watercolor lines replace these with synthetic surfactants and glycerin.
Are tempera and poster paints for kids vegan?
Many are, but not all. Some school tempera uses egg or casein as a binder, and many brands simply do not disclose. Choose a brand that states vegan or names its binder.
What is vegan cosmetics and how does it relate to paint?
Vegan cosmetics contain no animal-derived ingredients such as carmine, beeswax or lanolin, and are not tested on animals. Face paint for children is legally a cosmetic, so the same ingredient checks apply to it.
How can I tell if a kids’ paint set is vegan?
Look for an explicit vegan statement, check the ingredients or pigment codes for ox gall, honey, gelatin, casein, beeswax, carmine or bone black, check whether bundled brushes are synthetic, and email the manufacturer if the label is silent.
Next Step
Paint is not vegan when its binder, pigments, additives or brushes come from animals, or when it was tested on them. The main offenders are ox gall, honey, gelatin, casein, beeswax, shellac, carmine and bone black. None of them are necessary, and every one has a synthetic or plant-based substitute that works at least as well.
Rather than reading pigment codes on every box in the store, start with sets whose makers have already answered the question. Our guide to non-toxic vegan paint sets that are safe for kids lays out what each brand has disclosed so you can pick with confidence.
