Why it's rated this way

2 ingredients on this label are flagged. A cosmetic's rating is set by its most serious finding — here, Hydrolyzed Wheat Protein.

   Regulatory basis

   EU Cosmetics Regulation, Annex III — allowed only within set limits and conditions; Greenveil's curated cosmetic-ingredient concern list.

   How sure we are

   High confidence. The label names this substance exactly.

2. PolyacrylamideMinor concernFilm-forming or conditioning polymer made from acrylamide. The polymer itself is not the concern: the EU limits the leftover acrylamide monomer (a carcinogen) to 0.1 mg/kg in leave-on body products and 0.5 mg/kg in others, a purity specification the raw material has to meet.
