Watch this space if you have an iPhone/iPad, and care about which solvents are “greener” than others: a new app called Green Solvents has been submitted to the AppStore. The app is free/ad supported, and very simple: it lists solvents defined by the ACS Green Chemistry Initiative, with their environmental effects ratings.

The story behind this app is a triumph of social networking: it started with Sean Ekins posting a tweet, and a few days later, a new app was sitting on the iTunes AppStore waiting for review. More details coming soon!
