Argan Oil Moisture & Shine Shampoo

These describe what an ingredient is, not whether it is a problem. The stance marks above are the ratings; these are not.

• common irritantQuaternium 15, Methylchloroisothiazolinone, Methylisothiazolinone

  • Quaternium 15: A preservative the EU no longer permits in cosmetics; the ban followed a reproductive-toxicity classification and a finding that its safety could not be established. Prohibited in cosmetics by EU Regulation (EC) 1223/2009, Annex II entry 1386 (cis-1-(3-chlorallyl)-3,5,7-triaza-1-azoniaadamantane chloride, quaternium-15, CAS 51229-78-8), inserted by Commission Regulation (EU) 2019/831, which simultaneously deleted its Annex V entry 31 permitting it as a preservative. Recital 6 of that Regulation gives TWO grounds, not one: the cis-isomer "has been classified as a CMR substance of category 2", AND the SCCS opinion of 13 to 14 December 2011 concluded that "on the basis of the available data the safety of Quaternium-15 for use in cosmetic products cannot be established". The underlying classification is Regulation (EC) 1272/2008 (CLP) Annex VI index 612-251-00-9, inserted by Commission Regulation (EC) 790/2009: Flam. Sol. 2, Repr. 2 (H361d, "suspected of damaging the unborn child"), Acute Tox. 4, Skin Irrit. 2 (H315), Skin Sens. 1 (H317) and Aquatic Chronic 2. That entry carries no carcinogenicity classification of any kind. Skin Sens. 1 and Skin Irrit. 2 in the same entry are the harmonised classification behind this row's tag, so the tag rests on a sensitisation finding rather than on the reproductive-toxicity ground for the ban.
  • Methylchloroisothiazolinone: A preservative restricted to rinse-off products in the EU because of contact-allergy reports. EU Regulation (EC) 1223/2009, Annex V entry 39 (rinse-off only, 0,0015% of a 3:1 mixture with methylisothiazolinone). The reason is in Commission Regulation (EU) No 1003/2014, recital 3, quoted rather than summarised: "The SCCS concluded that the mixture of Methylchloroisothiazolinone (and) Methylisothiazolinone in a ratio of 3:1 does not pose a risk to the health of the consumer when used as a preservative up to a maximum authorised concentration of 0,0015 % in rinse-off cosmetic products, apart from its skin sensitising potential. The SCCS indicated that induction and elicitation would be less likely in a rinse-off product than when the same concentration is present in a leave-on product." SCCS/1238/09 concludes it "is well recognised as an important skin sensitiser at current conditions of use".
  • Methylisothiazolinone: A preservative that patch-test clinics see reactions to often enough that the EU banned it from leave-on products. American Contact Dermatitis Society, Allergen of the Year 2013 (Castanedo-Tardana MP, Zug KA, Dermatitis 2013;24(1):2-6); SCCS Opinion on Methylisothiazolinone (P94), Submission II, SENSITISATION ONLY (SCCS/1521/13, revision of 27 March 2014); banned in leave-on cosmetics by Commission Regulation (EU) 2016/1198, which recites the need to address "the increased incidence of allergies induced by methylisothiazolinone".

• undeclared fragrance blendFragrance

  • Fragrance: 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.
