Abstract
PURPOSE:To provide a compsn. which can suppress occurrence of putrefactive odor caused by microbial deterioration of a diluted soln. and lower the skin irritation, and which comprises as indispensable ingredients a particular ester of a p-hydroxybenzoic acid and a surfactant and exhibits a particular pH value in the form of a diluted soln. prepd. by dilution with water. CONSTITUTION:A water-soluble metal working oil compsn. comprises as indispensable ingredients at least one ester of p-hydroxybenzoic acid of formula I (wherein R is a 1-4C alkyl or benzyl group) and a surfactant and exhibiting a pH value of 7.0-8.5 in the form of a diluted soln. prepd. by dilution with water by a factor of 10-100 in terms of wt. Examples of the surfactant include anionic acid nonionic surfactants used in the art for a water-soluble metal working oil.
