iSUSTAIN™ Alliance Launched to Promote

Green Chemistry Awareness

SAN FRANCISCO, ACS SPRING EXPO-March 22, 2010-Beyond Benign Foundation, Cytec Industries Inc. and Sopheon announced today that they have formed the iSUSTAIN Alliance to promote Green Chemistry awareness in the global chemical industry.

The alliance has launched a website, www.isustain.com, which allows chemical manufacturers and users to track their progress in developing greener products over time. They will be able to assess the sustainability of new products using a systematic approach, which is both comprehensive and simple, to help shape the formulation of these products. The site allows companies to test their green product attributes and give each product an iSUSTAIN Green Chemistry Index rating which will be independently verifiable through a certification process.

The academic community will be able to use the iSUSTAIN application free of charge, while company users will pay a small subscription fee. An advisory board for the Alliance will be established in the coming months, which will include representation from the website's user community.

"As a non-profit organization dedicated to green chemistry education, we are excited to be involved with the iSUSTAIN Alliance. This new tool is long overdue and will be invaluable not only to industrial chemists designing safer processes and products, but also as a resource for students, educators and the designers of the next generation of molecules and materials," said John C. Warner, President of Beyond Benign and the President and Chief Technology Officer of the Warner Babcock Institute for Green Chemistry.

"Sustainability is a major strategic focus for a growing number of our customers," said Andy Michuda, Chief Executive Officer of Sopheon. "Many of them are already using our software and services to support their efforts to create and produce more environmentally friendly products. Our participation in the iSUSTAIN Alliance provides us with a unique opportunity to further our commitment toward helping product innovators in the global chemical industry achieve their social, environmental and business goals."

"Cytec has been seeking ways to become more sustainable on many fronts including energy, packaging, safety and product design. We use the iSUSTAIN product and process design tool to assist in these sustainability efforts," said Martin Court, Vice President for Research and Development, Cytec Specialty Chemicals.
