|  | Biodegradability of formulated cleaners is a primary consideration in the USEPA and GSA's Environmentally Preferable Purchasing (EPP) program. The EPP guideline recommends the use of "readily" biodegradable materials based on the European Organization of Economic Cooperation and Development (OECD) definition. This definition requires a level of 60% or greater be degraded in a standardized 28 day test. Biodegradability is also a major consideration when formulating household and institutional cleaners that are disposed of "down-the-drain".
Biodegradability studies with ExxonMobil Chemical LVP Fluids have been conducted by ExxonMobil Biomedical Sciences, Inc, at its environmental, health and safety facility. This laboratory meets the requirements of Good Laboratory Practice and is recognized for its capabilities and the expertise of its scientists. Test results using OECD method 301F (Manometric Respirometry) indicate many of ExxonMobil Chemical's LVP Fluids meet the criterion of "readily" biodegradable. Furthermore, in carefully controlled side-by-side biodegradability tests using the same method, the Exxsol LVP Fluids biodegraded at a rate similar to d-limonene while the Norpar LVP fluid biodegraded considerably faster.
