Description and Uses

Laurolactam (CAS 947-04-6) functions primarily as a polyamide monomer (e.g., PA6/PA12) in plastics and packaging applications. Trace amounts can persist as residuals or impurities and may migrate under certain conditions. Analytical testing focuses on identity confirmation and migration assessment under worst‑case time/temperature/simulant conditions to support material qualification and compliance. It is included in the Union list of Commission Regulation (EU) No 10/2011 for plastic materials and articles intended to come into contact with food.
