Removed several layers of paint but did not expose or remove lead paint layer, dimethyl glutarate, dimethyl adipate, dimethyl succinate, triethyl phosphate. Still have questions? Sign in with a different account. The level of exposure depends upon the dose, duration, and work being done. Can you explain the synthesis and reaction of a Grignard Reagent? Draw structures of OF2, BrF3, SCl2, XeF4, PF3 in a way that indicates their molecular shape. The methylene chloride is acting as a solvent for other nasties in the remover. Here’s a sampling of what is inside some of those products and how a few of them performed during a test conducted by C&EN. Numerous stripping products are sold in U.S. home improvement stores. In the meantime, consumer advocacy and environmental groups are pushing retailers to stop selling paint-removal products that contain methyl­ene chloride. Each of the women had a son who died from exposure to methyl­ene chloride in paint-stripping products purchased at home improvement stores. AS TESTED BY C&EN:Partially exposed wood substrate but did not effectively remove lead paint layer, INGREDIENTS PER SAFETY DATA SHEET (HIGH TO LOW):methylene chloride, methanol, toluene, acetone, INGREDIENTS PER SAFETY DATA SHEET (HIGH TO LOW):methylene chloride, methanol, toluene. It is used in paint removing, degreasing and cleaning, and manufacturing. At least four people have died from exposure to methyl­ene chloride in paint strippers since January 2017, when EPA proposed to ban such products, according to the Natural Resources Defense Council, an environmental group. Alternative paint removers that don’t contain methylene chloride, such as those with NMP, dibasic esters, and benzyl alcohol, “work much, much less effectively for multilayer applications,” Morose notes. Stripping products are also available without NMP. Password and Confirm password must match. Other experts say they would like to see more testing of the formulations developed by TURI. You can sign in to vote the answer. “Paint removers with methylene chloride work really well, in 20 minutes or less, for most multilayer applications,” says Greg Morose, research manager of the Toxics Use Reduction Institute (TURI) at the University of Massachusetts, Lowell. Removed the top layer of paint in a later 24-hour test. A methylene chloride-based formulation was the only one that exposed any wood on the cabinet door, but it left a layer of lead-based paint behind. Morose is managing a project at TURI that aims to commercialize alternative products that perform as well as methyl­ene chloride-based strippers without the safety risks. Each product was allowed to react with the paint for 30 minutes. It takes six to 12 hours for those products to work, he says. By continuing to use this site you are agreeing to our COOKIE POLICY. Methylene chloride is used in many industries. What is an allergy sensitizer, and how does a chemical become one? Chemical & Engineering News will not share your email address with any other person or company. In 2014, EPA reported that workers exposed to such products have an increased risk of cancer, as well as neurological and liver problems. The best bet is to read the label and follow the instructions there. The methylene chloride may not be what needs to be neutralized. Note: Not all products were tested by C&EN. In early May, three mothers traveled to Washington, D.C., to urge members of Congress and the U.S. Environmental Protection Agency to ban the use of methylene chloride in paint and coating removers. INGREDIENTS PER SAFETY DATA SHEET (HIGH TO LOW): INGREDIENTS PER SAFETY DATA SHEET (HIGH TO LOW):dimethyl adipate, dimethyl glutarate, PRODUCT NAME:Back to Nature ReadyStrip Plus, INGREDIENTS PER SAFETY DATA SHEET (HIGH TO LOW):N-methyl-2-pyrrolidone, benzyl alcohol, formic acid.
