Safer Alternatives in the Garment Cleaning Industry
There may be as many as 21,000 dry cleaning operations in the U.S. (EPA, 2019). Three chemicals, trichloroethylene (TCE), perchloroethylene (PERC), and n-propyl bromide (nPB), pose significant health and environmental concerns. All three have been used in paint, oil, and grease (POG) and organic stain removal, and two of these, PERC and nPB, are used as solvents in the main dry cleaning process in garment cleaning facilities.
In an analysis of currently available spotting removal products, a few POG spotting agents were found to still contain TCE or PERC. No spotting agents were found containing nPB. This analysis and report was made possible through a grant from U.S. EPA’s Source Reduction Assistance Program.
In the report, Alternative Spotting Chemicals for the Garment Cleaning Industry, Dr. Katy Wolf analyzed currently available POG spotting formulations for health and environmental characteristics, and provides guidance for safer alternative ingredients for some problem ingredients, relating to these chemical categories:
- Solvents like glycol ethers, glycol ether acetates, and hydrocarbons
In March 2020, PPRC hosted a webinar, Safer Alternatives in the Garment Cleaning Industry, presenting the U.S. EPA Safer Choice Program’s Safer Chemical Ingredients List (SCIL), the safer spotting chemical analysis by Dr. Katy Wolf, the King County Hazardous Waste Management Program and the Washington State financial incentives and technical assistance to transition dry cleaners from PERC to safer processes.
- Hazardous Waste Management Program in King County, Research Services, provides numerous current research reports on toxicity of dry cleaning chemicals, managing PERC in dry cleaning, and recommended PERC alternatives and incentives.
