INDUSTRIAL DETERGENT FOR HARD SURFACE

摘要

PROBLEM TO BE SOLVED: To obtain a detergent which is excellent in removing oils and fats adhered on surfaces of metal, glass or the like, and has little foamability and good biodegradability and does not contaminate the environment by employing a specific higher secondary alcohol alkoxylate. SOLUTION: A higher secondary alcohol alkoxylate prepared by the addition reaction of an 8-30C olefin with a (poly)alkylene glycol and/or a higher secondary alcohol alkoxylate obtained by further reacting the higher secondary alcohol alkoxylate with a 2-8C alkylene oxide is employed. The 8-30C olefin is a 8-30C aliphatic hydrocarbon having one double bond and can be linear or branched. The double bond may locate at theα-position or inside of the chain. As the (poly)alkylene glycols are employed those represented by the formula: HO(MO)m H (wherein M is 2-6C alkylene; and m is 1-20). Among these monoalkylene glycols are preferable.
