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

• common irritantp-PHENYLENEDIAMINE SULFATE

  • p-PHENYLENEDIAMINE SULFATE: A hair-dye coupler and one of the most frequently positive substances in patch-test clinics. EU Regulation (EC) 1223/2009, Annex III entry 8a permits p-phenylenediamine and its salts as a hair dye substance in oxidative hair dye products, at a maximum of 2% free base applied to hair after mixing; entry 8b separately permits them in products intended for colouring eyelashes, professional use only, at the same 2% limit, so this is not a hair-dye-only restriction. The general-use wording entry 8a mandates begins with the mixing ratio, then "Hair colourants can cause severe allergic reactions", "Read and follow instructions", "This product is not intended for use on persons under the age of 16", "Temporary “black henna” tattoos may increase your risk of allergy", a three-part "Do not colour your hair if" contraindication list, "Contains phenylenediamines" and "Do not use to dye eyelashes or eyebrows". The professional-use wording PREPENDS "For professional use only." and ends "Wear suitable gloves." where the general one ends with the eyelash sentence.

• fragrance materialLINALOOL, BENZYL ALCOHOL

  • LINALOOL: A floral fragrance component named separately on the label. EU Regulation (EC) 1223/2009, Annex III entry 84: a fragrance substance whose presence must be indicated in the list of ingredients above 0,001% in leave-on and 0,01% in rinse-off products, because of established contact-allergy risk.
  • BENZYL ALCOHOL: Used both as a fragrance component and as a preservative; the EU names it either way. EU Regulation (EC) 1223/2009, Annex III entry 45: a fragrance substance whose presence must be indicated in the list of ingredients above 0,001% in leave-on and 0,01% in rinse-off products, because of established contact-allergy risk. That entry carries transition footnote (38), which is footnote (37) plus a condition: stock that does not comply may still be made available until 31 July 2028 only "provided that they comply with the restrictions applicable on 15 August 2023", and only if it was lawfully placed on the Union market before the 31 July 2026 cut-off. Entry 45 covers its non-preservative use; it is separately an allowed preservative at Annex V entry 34.

• 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.

• humectantGLYCERIN

  • GLYCERIN: A humectant, and one of the two ingredients a comparison of moisturiser components found made a significant difference to skin hydration. FDA OTC skin protectant monograph, 21 CFR 347.10(h), lists glycerin as a skin protectant at 20 to 45%. On the humectant half: Jeong CB, Han JY, Cho JC, Suh KD, Nam GW, "Analysis of electrical property changes of skin by oil-in-water emulsion components", Int J Cosmet Sci 2013;35(4):402-410, DOI 10.1111/ics.12059, PMID 23621673, found that "glycerine and urea showed significant skin hydration effects compared with other humectants".
