• common irritantMELALEUCA ALTERNIFOLIA LEAF OIL, PROPYLENE GLYCOL

  • MELALEUCA ALTERNIFOLIA LEAF OIL: An essential oil whose oxidation products carry its sensitising potential; the EU assesses it as a moderate skin sensitiser. SCCS Scientific Opinion on Tea Tree Oil (CAS/EC 68647-73-4 / 285-377-1), SCCS/1681/25, adopted 30 October 2025, which concludes it is a moderate skin sensitiser. It does not set maximum levels of its own: it assesses the concentrations the applicant defended, and finds no concern at 2,0% in shampoo, 1,0% in shower gel, 1,0% in face wash and 0,1% in face cream, for oil conforming to ISO 4730:2017, in adults, in non-sprayable formats. It draws on the earlier SCCP opinions SCCP/1155/08 and SCCP/0843/04 and incorporates their data by reference; it says nothing about their status.
  • PROPYLENE GLYCOL: A solvent that shows up in patch-test clinics, more often as irritation than as allergy. American Contact Dermatitis Society, Allergen of the Year 2018 (Jacob SE, Scheman A, McGowan MA, Dermatitis 2018;29(1):3-5).

• undeclared fragrance blendPARFUM

  • PARFUM: A blend the label does not itemize, so what is in it cannot be read from the ingredient list. EU Regulation (EC) 1223/2009 permits the collective term "parfum"; the SCCS Opinion on Fragrance Allergens (SCCS/1459/11) reviews the contact-allergy evidence for the substances it can contain.
