The claim that they appear to be making for this product (I only read the blurb you provided below) is that the production process is greener. You could be producing something that is equally as terrible and toxic as what it is replacing, but as long as the production method is less toxic or wasteful or comes from renewable feedstocks, for example, then you can claim that overall it is a ‰??greener‰?? product than what it replaced.

The amount of ‰??data not available‰?? slots is pretty infuriating, and makes doing an objective examination of your own processes more difficult than it really should be at this point in the game. This level of difficulty dissuades all but the safety/green chemistry evangelicals from truly examining their work with sustainability in mind.

>> 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.
