Coverage & match quality

5 ratings · 1 of 4 axes

Some ratings rest on an automatic match that has not been human-reviewed.
Fewer raters reach smaller-brand products, so a missing rating is not a clean bill of health, only a gap.

What these ingredient tags mean (3)

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

commonly dryingALCOHOL DENAT
- ALCOHOL DENAT: Denatured ethanol: a fast-evaporating solvent that thins a formula and leaves a dry finish. International Chemical Safety Card ICSC 0044, Ethanol (anhydrous), prepared by an international group of experts for the ILO and WHO: "The substance defats the skin, which may cause dryness or cracking." WHO Guidelines on Hand Hygiene in Health Care (2009) records depletion of the skin lipid barrier by lipid-dissolving alcohols, and also that "the lipid-dissolving effect of alcohols is inversely related to their concentration". Both describe stronger exposures than a cosmetic formula.
comedogenic in testingISOPROPYL MYRISTATE
- ISOPROPYL MYRISTATE: A light emollient, and the ester the rabbit-ear literature names first. Fulton JE Jr, Pay SR, Fulton JE 3rd, "Comedogenicity of current therapeutic products, cosmetics, and ingredients in the rabbit ear", J Am Acad Dermatol 1984;10(1):96-105, PMID 6229554. The openly readable abstract names this ingredient among its "ingredient offenders", in prose and without a numeric rating: "Ingredient offenders include isopropyl myristate and its analogs, such as isopropyl palmitate, isopropyl isostearate, butyl stearate, isostearyl neopentanoate, myristyl myristate..." The rabbit-ear assay rates raw ingredients and does not predict how a finished formula behaves on human skin.
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.
