It is anticipated that the PMN substance will replace conventional telomer-based perfluorinated polymeric compounds currently used in textile treatments, which may contain C-8, C-10, C-12 or higher chain length components. In contrast, the PMN substance does not contain polymeric materials or impurities with chain lengths greater than six carbons and, as a result, presents a more favorable risk profile than conventionally marketed telomer-based products, by eliminating any potential for environmental release of perfluorinated carboxylic acids of chain lengths greater than C-6. *************************************************************** CONFIDENTIAL -- CBI **************************************************
