Abstract
A biodegradable liquid degreaser for use as a parts cleaner is described. The composition includes from about 0.5% to about 2% by weight of an alkali metal hydroxide; from about 0.5% to about 5% by weight of a corrosion inhibitor; from about 1.5% to about 15% by weight of a biodegradable terpene solvent; from about 5% to about 30% by weight of a biodegradable surfactant; from about 5% to about 15% by weight of a biodegradable co-solvent/co-surfactant and the balance consisting of water. The composition provides excellent degreasing of machine parts while being safe and pleasant to use. The advantage is an inexpensive, completely biodegradable, non-volatile composition for use as a machine part degreaser.
