All of Nalco’s oil spill dispersants have to pass stringent third part performance evaluations before being accepted for use by the Environmental Protection Agency (EPA). Furthermore, extensive environmental testing has to be performed on all oil spill dispersants to ensure that their impact on the aquatic environmental is minimal. For this reason, only those components that are known to have favorable environmental properties are used in oil spill dispersant products. Many of these components are readily used to stabilize food products, cosmetics or in pharmaceuticals. [links to company statements on test results by US EPA]
