Pagination or Media Count:
An aqueous mineral oil and nitrite-free cooling lubricant for noncutting and cutting metal working is characterized by a combination of alkysulfamido carboxylic acids of their salts with a chain length of at least 6 C atoms with polyethylene glycols having a molecular weight of from 200 to 1500 and, if necessary, additional additives to improve the dissolvability characteristics and the corrosion protection, such as organic bases, preferably triethanolamine, alkanolamine or alkaline salts of unsaturated straight chained monofatty acids and highly sulfanated fatty acids or other salts.
