No, our products do not contain NPE.
NPE stands for Nonyl Phenoxy Ethoxylate. NPE is a synthetic (petroleum-derived) nonionic surfactant (cleaning agent) used in cleaning products. Common applications include laundry liquid detergents and hard surface cleaners (spray cleaners and dilutable cleaners.)
NPE has been determined to be estrogenic. That is, it can mimic the hormone estrogen. In laboratory studies, exposure to NPE has resulted in hermaphroditic (fish with both male and female sexual organs).  There is also experimental evidence that NPE reduces sperm counts in rats.
