The Clean² Face Pads are made with both USA Cotton and viscose. We use the same viscose that we make the Clean Towels with. To make this signature fabric, eucalyptus is harvested from managed plantations, then broken down into chips that are then washed and cleaned. The chips are dissolved (turning them into viscose), and then sent through a spinneret which produces the soft, cellulose fibers. This fiber is then stretched and pressed, creating the signature fabric for our Clean Towels and Clean² Face Pads. This fabric is certified with OEKO-TEX, PEFC, USDA Biobased Product, and is certified fully biodegradable and compostable.
