Synopsis Commercially available copolymers of 1‐vinyl‐2‐pyrrolidone and 1‐vinyl‐3‐methylimidazolium chloride, known as ‘Luviquat’ types in the cosmetic industry, were analysed for their composition using a combination of pyrolysis–gas chromatography–mass spectrometry method. This is a report on the determined pyrolytic products and the fast identification of the analysed polymers both in raw materials and cosmetic products. Calibration with defined material ensures the determination of monomer ratios with good reproducibility.
