Abstract
An industrial detergent useful for degreasing and cleansing of metal parts, which is in the form of an aqueous solution and comprises 3 to 20 parts by weight of a fatty acid sucrose ester as a nonionic surfactant, 3 to 15 parts by weight of polyoxyethylene alkyl ether also as a nonionic surfactant, 1 to 10 parts by weight of a chelating agent for metal ions typified by EDTA, 1 to 5 parts by weight of a petroleum sulfonic acid salt, preferably an alkanolamine salt, as a rust-inhibiting agent and 3 to 10 parts by weight of propylene glycol. Optionally small amounts of sorbitol and/or CMC may be added. This detergent is weak in alkalinity but strong in deterging power, and the organic surfactants are harmless to the human body and can be decomposed by microorganisms.
