I think this goes back to the term "green" being an environmental
term. It is not always synonymous with safer for workers.� If the
environmental impacts are lower, it can be designated� as a
"greener" alternative.
I could be mistaken, but this has always been my understanding of
the term.� Not to mention how very few chemicals have been fully
investigated toxicologically....
S-
After reviewing the SDS for this new product, I have a philosophical question:�Can a "Greener Chemical" have a "no data available" section on it's SDS?�That is, shouldn't a complete hazard assessment be required before such a claim is made? It seems to me that a SDS provides the outline of the various aspects of a chemical's hazards that should be systematically investigated before such a conclusion is reached...
Oddly, Section 12.1 Toxicity Data says "No data available" and then lists some data.

BURLINGTON, Mass., April 24, 2019 /3BL Media/�?? MilliporeSigma today launched Cyrene?� �?? a sustainable dipolar aprotic solvent, produced in two steps from a renewable cellulose source. The bio-derived alternative was created in response to the need for solvents to meet stricter regulation requirements for both employee safety and environmental sustainability. The new product targets the rising demand for greener alternatives to Dimethylformamide (DMF) and N-Methyl-2-pyrrolidone (NMP).
�??With a strong focus on green chemistry, MilliporeSigma is dedicated to providing today�??s scientists with innovative solutions to help solve environmental challenges before us,�?? said Klaus Bischoff, head of Research Solutions, MilliporeSigma. �??As a greener alternative, Cyrene?� solvent allows our customers to improve the safety of their processes and reduce the environmental impact of their research and manufacturing �?? without compromising performance.�??
MilliporeSigma uses the 12 Principles of Green Chemistry that were developed and published by thought leaders Paul T. Anastas and John C. Warner in 1991 as a framework for its Green Chemistry practice.
DMF and NMP are under increasing regulatory restrictions, with both being classified by the European Union�??s Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) as substances of very high concern. More recently, according to the European Union, the European Commission added NMP to the restricted substances list known as REACH Annex XVII �?? driving the demand for alternatives. Additionally, effective May 2020, consumer products containing more than 0.3 percent NMP will be prohibited in the European Union. Initial studies and testing have found Cyrene?� solvent to be a more sustainable, safer option when compared with DMF and NMP.
