Coverage & match quality
11 ratings · 2 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 (2)
These describe what an ingredient is, not whether it is a problem. The stance marks above are the ratings; these are not.
commonly dryingIsopropyl Alcohol
- Isopropyl Alcohol: A fast-evaporating solvent with a drying finish, common in toners and hand products. International Chemical Safety Card ICSC 0554, Isopropyl alcohol, prepared by an international group of experts for the ILO and WHO: "Repeated or prolonged contact with skin may cause dryness and cracking." It describes a stronger exposure than a cosmetic formula.
common irritantFormaldehyde
- Formaldehyde: A preservative and a recognised contact allergen; the EU prohibits it in cosmetic products. American Contact Dermatitis Society, Allergen of the Year 2015: Pontén A, Bruze M, "Formaldehyde", Dermatitis 2015;26(1):3-6, DOI 10.1097/DER.0000000000000075, PMID 25581665; prohibited in cosmetics by EU Regulation (EC) 1223/2009 Annex II entry 1577, inserted by Commission Regulation (EU) 2019/831, which also deleted its Annex III and Annex V entries, so no nail-hardener use survives.
