Chemical Use
  • Cintas is the first major industrial laundry company to make the corporate-wide switch from detergents that contain Nonylphenol Ethoxylates ("NPEs") to detergents that do not contain NPEs.

    • Nonylphenol Ethoxylates (NPEs) are a class of surfactants (detergents) that have been used for the past 50 years by many industries, including industrial laundries. NPEs are manufactured from petroleum-based products. The non-NPE products are made from natural plant oils.

    • In recent years, wastewater analytical testing methods have improved to the point where, at some treatment plants, Nonylphenol (NP) has been detected in the water leaving the plants. NP is created when NPE degrades. Some studies have linked NP with toxicity to fish. Cintas' new non-NPE detergents are more easily biodegraded in treatment plants and; therefore, will eliminate any potential of the impact that the NP could have on fish.
