Characterization of off-odours and potentially harmful substances in a fancy dress accessory handbag for children

Abstract A fancy dress accessory handbag for children was claimed by consumers to exhibit an offensive smell. Sensory characterization by an expert panel revealed, amongst others, rubber- and car tire - like notes. For elucidation of the molecular reasons of this sensory defect, the volatile fractio...
