About
A plant-derived (soy) quaternary ammonium compound with a short PEG-3 chain, used for conditioning but carrying standard PEG concerns.
PEG-3 disoyoylamidoethylmonium methosulfate is a soy-derived quaternary ammonium salt ethoxylated with approximately 3 moles of ethylene oxide (PEG-3). The short EO chain presents a moderate risk of 1,4-dioxane contamination. The ingredient is used as a conditioning agent and is not specifically listed in EU Annex II or III of the Cosmetics Regulation, but residual ethylene oxide must be controlled per cosmetic manufacturing best practices (IFRA guidelines).
