Are Tattoo Inks Safe in Australia? What the 2026 UNSW Study Actually Found
In January 2026, a study led by researchers at UNSW Sydney found that every tattoo ink they tested — purchased from Australian suppliers — failed at least one European Union safety standard. The study detected toxic metals including arsenic, cadmium, chromium, and lead, as well as carcinogenic compounds, in 15 black and coloured inks from major international brands.
The story was picked up widely, and understandably so. If you’ve been tattooed in Australia, or you’re planning to be, it’s a reasonable thing to want to understand.
Here’s what the study actually found, what the researchers themselves said about it, and what it means practically for people getting tattooed in Australia.
What the Study Found
The UNSW research team, led by Professor William Alex Donald, analysed 15 tattoo inks available from Australian suppliers using advanced chemical analysis techniques. The inks included both black and coloured formulations from established international brands widely used by tattoo artists.
The findings were significant. Eight metals restricted under EU law were detected at levels exceeding EU limits in at least one ink: antimony, arsenic, cadmium, chromium, copper, lead, selenium, and tin. Additional pigment metals — titanium, aluminium, and zirconium — were found at high concentrations, though these aren’t currently regulated under EU rules.
The study also detected organic compounds of concern. Toluidine, a carcinogenic aromatic amine banned under EU tattoo ink regulations, was found in three of the 15 inks. Sulphanilic acid, which is not considered suitable for human consumption or therapeutic use, was detected in nine inks.
Every single ink tested would have been prohibited from sale under EU regulations.
The study was published in the Journal of Hazardous Materials in January 2026. It was triggered, interestingly, by a high school student — Bianca Tasevski, then at St Mary Star of the Sea College in Wollongong — who contacted UNSW’s School of Chemistry to ask what was actually in tattoo inks as part of her senior year research project.
What the Researchers Said About It
The most important thing to understand about this study is what the researchers themselves concluded — which was notably more measured than the headlines suggested.
Professor Donald was direct: the findings are not cause for panic. The study analysed chemical composition, not health outcomes. Finding a substance at a level that exceeds EU limits is not the same as demonstrating that it causes harm in the concentrations found in tattoo ink.
What the researchers called for was not a moratorium on tattooing or alarm about existing tattoos. They called for Australia to introduce routine sampling, testing, and binding national regulatory standards that align with international benchmarks. Australia currently has no equivalent to the EU’s regulatory framework for tattoo inks, which has been legally enforced since 2022. The current system relies on voluntary compliance and occasional government surveys.
The study was a snapshot of 15 inks at one point in time, from one group of suppliers. It was not a comprehensive surveillance exercise across all inks available in Australia. The researchers themselves noted this distinction.
What This Means for Existing Tattoos
If you have tattoos, this study doesn’t change anything about your current situation. The ink is already in your skin. Worrying about it retrospectively serves no purpose and the researchers explicitly said this isn’t cause for panic.
What we do know from existing research is that tattoo pigments can persist in the skin long term and that some pigment particles migrate to lymph nodes over time. This has been known for years and is part of the broader conversation about tattoo ink safety internationally. The long-term health implications of this are still being studied.
What we don’t know is whether the specific concentrations of metals found in this study cause meaningful health harm at the exposure levels involved in tattooing. The study didn’t assess health outcomes — it assessed chemical composition.
What This Means If You’re Planning to Get Tattooed
This is where the study has more practical relevance. A few things worth thinking about:
Ask your studio about their inks. Reputable studios typically use established professional-grade inks from known suppliers. The brands tested in this study were described as “major, established international brands” — so brand recognition alone isn’t a guarantee of safety under Australian conditions. But studios that are transparent about their ink suppliers and engaged with the safety conversation are generally a better choice than those who aren’t.
EU-compliant inks exist. The EU has had binding ink safety regulations since 2022. Some Australian studios and suppliers have proactively sourced inks that meet EU standards, even though Australian regulations don’t require it. It’s worth asking your artist whether they’re using EU-compliant inks — a good artist will know what’s in the products they’re using.
Coloured inks carry different risks to black. The study found that black inks tended to contain a broader range of regulated metals, while brightly coloured inks often had high concentrations of specific pigment-associated metals. If you have concerns, this is worth factoring into conversations with your artist about ink choices.
The regulatory gap is a systemic issue, not an individual one. The absence of binding Australian standards for tattoo inks is the actual problem the researchers identified. Individual consumers can’t easily verify what’s in any given ink — that’s exactly why binding testing and disclosure requirements are needed at a regulatory level.
The Regulatory Picture in Australia
Australia currently has no binding national regulatory framework for tattoo inks equivalent to the EU’s Commission Regulation 2020/2081. The EU’s rules, enforced since 2022, set specific chemical limits for tattoo inks and require manufacturers to demonstrate compliance.
In Australia, market oversight relies on voluntary compliance and occasional government characterisation surveys, the most recent of which predate the EU’s current legally binding rules. Professor Donald noted that publicly available data on ink composition in Australia is sparse — the chemical composition of inks currently sold here remains largely unknown at a population level.
Similar issues with tattoo ink composition have been documented in the United States, Sweden, and Turkey — so this isn’t uniquely Australian. But Australia’s lack of binding standards means there’s no systematic mechanism to identify and remove non-compliant inks from the market.
The researchers’ recommendation was clear: Australia needs to introduce routine sampling and testing across brands and batches, and to harmonise its standards with international benchmarks.
What You Can Do
Research your studio’s ink practices. Ask what brands they use and whether those brands have EU compliance documentation. A studio that can answer this question confidently is one that takes ink safety seriously.
Look for studios using EU-compliant inks. Some Australian studios have proactively made the switch. It’s becoming a more common question from clients, and good studios are paying attention to it.
Don’t panic about existing tattoos. The researchers said this themselves. The study identified a regulatory gap and called for systemic change. It wasn’t a finding that existing tattooed people face imminent health risks.
Stay informed. This is an evolving area. Australian regulatory bodies may introduce new standards in response to research like this. The TGA (Therapeutic Goods Administration) oversees some aspects of tattooing-related products in Australia, and regulatory change is possible as the evidence base grows.
The Bottom Line
The UNSW study found something real and worth taking seriously: Australian tattoo inks are largely unregulated, and every ink tested contained substances that would be prohibited under EU law. This is a genuine gap that needs a systemic regulatory response.
What it doesn’t mean is that getting tattooed in Australia is acutely dangerous, or that people with existing tattoos are at immediate risk. The researchers themselves made this distinction clearly.
The practical response is to be an informed consumer — ask questions of your studio, look for artists who are engaged with ink safety, and support calls for stronger Australian regulation of tattoo ink composition.
