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

• common irritantPROPYLENE GLYCOL, DMDM HYDANTOIN

  • 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).
  • DMDM HYDANTOIN: A preservative the FDA lists as a formaldehyde releaser, which is why formaldehyde-reactive skin can notice it. How much reaches the skin depends on the whole formula, not on this name alone. EU Regulation (EC) 1223/2009, Annex V entry 33, permits DMDM hydantoin as a preservative up to 0,6%. The FDA names it among the "formaldehyde and formaldehyde releasing ingredients" on its Allergens in Cosmetics page (content current 25 February 2022). SCCS Scientific Advice SCCS/1632/21, on the threshold for the "contains formaldehyde" warning, describes a study in which a moisturiser spiked to the 0,6% Annex V maximum released at least 40 ppm formaldehyde. Annex V preamble point 2, as amended by Commission Regulation (EU) 2022/1181, requires the warning "releases formaldehyde" on any product whose total released formaldehyde exceeds 0,001% (10 ppm). That Regulation states the sensitisation ground itself, so the chain is drawn by the regulator and not by us: recital (2) names the class, "Certain of those preservatives are gradually releasing formaldehyde in order to fulfil a preserving function in the final cosmetic product (so called formaldehyde releasers)", and recital (3) gives the purpose of the warning, "In order to inform consumers sensitised to formaldehyde about the presence of formaldehyde that may trigger an allergic reaction". Recital (1) records that formaldehyde is classified a skin sensitizer (Category 1) in Part 3 of Annex VI to Regulation (EC) 1272/2008.

• rich occlusiveMINERAL OIL, PETROLATUM

  • MINERAL OIL: A refined oil that sits on the surface of the skin; it has a heavy finish. FDA OTC skin protectant monograph, 21 CFR 347.10(l): "Mineral oil, 50 to 100 percent; 30 to 35 percent in combination with colloidal oatmeal in accordance with 347.20(a)(4)."
  • PETROLATUM: A barrier that sits on the surface of the skin, which is also why it feels heavy. FDA OTC skin protectant monograph, 21 CFR 347.10(m) and (r), lists petrolatum and white petrolatum as skin protectants at 30 to 100%.

• 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".
