The European Chemicals Agency issued the REACH Annex VIII approval. Cyrene, a chiral dipolar aprotic solvent, was developed in conjunction by Circa and the Green Chemistry Centre of Excellence at the University of York. The process is a two-step conversion beginning with waste biomass.
Cyrene provides a safer alternative to polar aprotic solvents facing regulatory pressure worldwide, Circa says.
“Annex VIII authorization is a major milestone for Cyrene and we are delighted to have been given the go-ahead to sell Cyrene in significantly larger quantities in Europe,” Tony Duncan, CEO and co-founder of Circa Group says. “Safer solvents are urgently required and with Cyrene, we are also offering a bio-based solution with a unique property set, including viscosity, surface tension and polarities – making it an exciting new prospect for advanced materials. Our next goal is registration of Cyrene in the US and other jurisdictions will soon follow.”
