Abstract
Disclosed is a polyurethane foam and a method of preparing the same which utilizes only bio-renewable polyols and no petroleum derived polyols. The polyol is derived from a bio-renewable source and has a bio-renewable content of at least 70% by weight. The produced foams have mechanical and performance properties that are equal to or exceed those of similar polyurethane foams produced using petroleum derived polyols. The foams are preferably formed into sponges and other cleaning products for use by consumers and in industrial settings.
