  1. GREENER CHEMICAL PRODUCTS AND PROCESSES STANDARD GC Chemical Characteristics Task Group presentation to Joint Committee on Greener Chemical Products and Processes American Chemical Society Green Chemistry Institute Washington DC October 20, 2009

  2. STANDARD FOR GREENER CHEMICAL PRODUCTS AND PROCESSES GC CHEMICAL CHARACTERISTICS TASK GROUP Approach • Developed list of chemical characteristics • Categories • Subcategories • Criteria, potential route of exposure • Examples of tests to inform the criteria • Matrix of information needed based on intended application, (e.g., closed process, industrial operations, dispersive use) • Developed list of filter criteria • Applied filter to chemical criteria to determine if appropriate for this standard at this time

  3. STANDARD FOR GREENER CHEMICAL PRODUCTS AND PROCESSES GC CHEMICAL CHARACTERISTICS TASK GROUP Chemical Characteristic Filter Criteria • 1. Is there an established definition? Definable? • 2. Is there a validated test? Measurable? • or • 3. Is there a generally accepted methodology, calculation, model? • 4. Is the test/method commonly done?

  4. STANDARD FOR GREENER CHEMICAL PRODUCTS AND PROCESSES GC CHEMICAL CHARACTERISTICS TASK GROUP 3-Tiered Approach 3. Potential Future Considerations No mention in this Standard Characteristics that may be added to this Standard at some future time (e.g., size– nanomaterials; genomics 2. State-of-the-Science Statement Include text statement in thisStandard Evolving characteristics – do not yet fulfill our Filter Criteria (e.g., 14-Day Worm, Endocrine Disrupters) 1. Chemical Characteristics List as a Chemical Characteristic for evaluation in this Standard Characteristics that fulfill 3 of our 4 Filter Criteria

  12. STANDARD FOR GREENER CHEMICAL PRODUCTS AND PROCESSES GC CHEMICAL CHARACTERISTICS TASK GROUP SUMMARY • Standard needs to be practical, usable, and provide relevant information • Group has developed a recommended list of chemical characteristics that: • Have established definitions, • Are measurable using validated tests or are calculable using standard, accepted methods, and • Have tests that are done commonly. • Provide relevant information from a supplier to his customer.
