Moth-Proofing Agent Residues in Wool Products
topic
Moth-proofing residue analysis targets permethrin, cypermethrin, and the now-banned organochlorine dieldrin in wool textile specimens by GC-MS after acetone-hexane extraction with gel permeation chromatography cleanup, quantifying residual insecticide concentrations against OEKO-TEX and national regulatory maximum residue limits for skin-contact wool products.
Role
Ensures wool carpets, blankets, and apparel treated with moth-proofing insecticides during dyeing or finishing do not present unacceptable dermal exposure risks, with particular focus on identifying legacy dieldrin contamination in vintage wool products and verifying that replacement pyrethroid treatments are applied within safe concentration limits.
