Important SCCS Announcement Regarding Tea Tree Oil

A new scientific opinion has been published by the SCCS (Scientific Committee on Consumer Safety), operating under the European Union Cosmetics Regulation, regarding Tea Tree Oil (TTO), which is widely used in cosmetic products.

SCCS Opinion Number: SCCS/1681/25
Publication Date: 30 October 2025

This new assessment clearly defines the safe conditions of use and maximum concentration limits of Tea Tree Oil in cosmetic products.

Maximum Safe Use Levels According to SCCS

According to the SCCS evaluation, Tea Tree Oil (TTO) is considered safe only in the following product categories and at the specified maximum concentrations:

  • Shampoo: 2.0%

  • Shower Gel: 1.0%

  • Facial Cleansing Products: 1.0%

  • Face Cream: 0.1%

Exceeding these limits may pose a risk to product safety.

Critical Conditions for Safe Use

The SCCS safety assessment is conditional upon the following mandatory requirements:

✔️ Tea Tree Oil must comply with ISO 4730:2017 (and the updated ISO 4730:2025 revision)
✔️ Products must be intended exclusively for dermal use by adults
✔️ Products must not be presented in aerosol or spray form
✔️ The stability of TTO must be ensured throughout the product’s shelf life so that it remains within ISO specifications

Failure to meet these conditions may result in the product being considered non-compliant with cosmetic regulations.

  • Re-evaluation of formulations
