Tea Tree Oil: Restriction or Ban?
In recent years, tea tree oil (TTO), with the INCI name Melaleuca alternifolia Leaf Oil, has been receiving increasing attention from European Regulatory Authorities due to concerns related to skin sensitization, reproductive toxicity, and systemic exposure under certain conditions of use.
But after all, what is tea tree oil? It is a natural ingredient widely used in the cosmetic industry, present in facial care products, shampoos, shower gels, and anti-acne formulations, due to its antimicrobial, purifying, and soothing properties.
In November 2023, the Risk Assessment Committee (RAC) of the European Chemicals Agency (ECHA) proposed classifying tea tree oil as a category 1B reproductive toxic substance under the CLP Regulation (EC) No 1272/2008.
In European legislation, a CMR (carcinogenic, mutagenic, or toxic for reproduction) classification is not just a hazard warning. According to Regulation (EC) No 1223/2009, substances classified as CMR are, in principle, banned in cosmetic products, except in situations where it is demonstrated, through a rigorous scientific assessment, that its use is safe under real exposure conditions.
It was precisely this link between toxicological classification and potential cosmetic ban that sparked concern across the industry and among consumers.
Will Tea Tree Oil Actually Be Banned?
Following the RAC's opinion, the technical dossier was analyzed by the Scientific Committee on Consumer Safety (SCCS), the entity responsible for evaluating ingredient safety under real conditions of cosmetic use.
In November 2025, the SCCS published its opinion, concluding that tea tree oil can be safely used in cosmetics under specific conditions. According to the SCCS, tea tree oil can be used up to:
2.0% in shampoos;
1.0% in shower gels and facial cleansing products;
0.1% in facial creams (leave-on).
The SCCS also established some important conditions:
Compliance with the ISO 4730:2017 standard;
Exclusion of spray or aerosol formulations due to inhalation risks;
Control of oil stability to prevent oxidation and the formation of sensitizing compounds;
Maintaining consumer exposure within the established margin of safety.
Additionally, the SCCS states that oxidized fractions of the oil can significantly increase skin sensitization potential, making factors such as proper storage, protection against oxidation, and packaging compatibility essential.
What Alternatives Are Being Used?
With rising regulatory pressure on tea tree oil, many formulators have been exploring alternatives with similar properties.
For anti-acne formulations and antibacterial action, ingredients such as Manuka Oil, Niacinamide, and Willow Bark Extract stand out. For antifungal action, oregano, thyme, and clove oils are frequently used.
In soothing and repairing products, ingredients like bisabolol, centella asiatica, allantoin, and calendula extract continue to be widely used.
In practice, the current trend leans more toward combining multiple active ingredients with different mechanisms of action rather than directly replacing it with a single ingredient.
Conclusion
The current outlook points toward specific restrictions on use rather than a total ban of the ingredient from the European market. As of July 2026, the application of [these restrictions]* is expected, and products that do not comply with the established limits will no longer be permitted on the EU market.
The case of Tea Tree Oil clearly demonstrates the direction that European cosmetic regulation is heading—greater scientific rigor, an increasing focus on evidence-based safety, and heightened regulatory pressure on natural ingredients whenever toxicological data is incomplete or contradictory.
