Replacement of Trichloroethylene as a solvent in the production of caprolactam

Replacement of Trichloroethylene as a solvent in the production of caprolactam

One company using Trichloroethylene in the extraction process of caprolactam has submitted an Application for Authorisation to the European Chemicals Agency ECHA to allow continued use. This request is hence a call for alternative providers to submit to ECHA information about their possible technology that could replace Trichloroethylene in this process. All kinds of alternatives are highly wanted; Alternative solvents, process changes and alternative technologies which can lead to the substitution of Trichloroethylene in the production of caprolactam.

Also alternatives, not yet on the market but under development are of interest for the consultation, which you can find here:  

Conditioning agents for skin and hair cleansing products

Conditioning agents for skin and hair cleansing products

Alternatives for cationic poly-electrolytes (quaternary ammonium derivatives or polyquaterniums), generally used as conditioning agents for skin and/or hair cleansing products, that are biodegradable and have low ecotoxicity.

For use as raw materials for formulated personal care products.

Biodegradable chelating agents

Biodegradable chelating agents

Biodegradable chelating agents for personal care and household products including dishwashing and laundry detergents. Biodegradable alternatives should have comparable performance to ethylenediaminetetraacetic acid (EDTA), and meet the US EPA Safer Choice criteria for chelating and sequesting agents (Design for the Environment Program Criteria for Chelating and Sequestering Agents, Office of Pollution Prevention & Toxics, U.S. Environmental Protection Agency, 2010.)
