I’ve been blogging over the last week about how political appointees at EPA are starting to clear new chemicals to enter commerce based on a new – apparently unwritten and certainly not public – review process that ignores the law and will put the health of the public, workers and the environment at greater risk than even under the weak reviews conducted before Congress’ 2016 overhaul of the Toxic Substances Control Act (TSCA).
The first green light was given to a fragrance chemical intended for use in a wide array of everyday consumer products. Here is its formal name, a simpler synonym used by its manufacturer, and an identifier called a CAS number:[pullquote]Late in the review process EPA switched to analogue chemicals to estimate toxicity that are 500-fold less toxic than the analogue identified by the company and EPA’s own models.[/pullquote]
- Name: Oxirane, 2-methyl-, polymer with oxirane, bis[2-[(1-oxo-2-propen-1-yl)amino]propyl] ether
- Synonym: Jeffamine diacrylamide
- CAS: 1792208-65-1
In this post I want to look more at what is known – and not known – about the chemical’s hazards. While the chemical is a polymer, it includes “low molecular weight (LMW) components” that are the primary hazard concern. Read More
