Abstract (en)

[origin: WO2010149250A1] The invention relates to compositions containing a basic oil or base oil, 10 to 50 percent by weight of ether pyrrolidone carboxylic acids of formula (1) or the salts thereof of formula (1), wherein R1 representsC8-C30-alkyl, C8-C30-alkenyl, C6-C30-aIyI, C7-C30-alkylaryl, M represents hydrogen, alkali metal, alkaline earth metal, or ammonium, X represents C2-C6-alkylene, or a poly(oxyalkylene) group of formula (2), wherein I is a number ranging from 1 to 50, m, n are numbers ranging from 0 to 50 independently of I and independently of one another, R2, R3, and R4 independently represent hydrogen, CH3, or CH2CH3, Y represents C2-C6-alkylene, said compositions further containing a specific amount of a pH regulator/neutralizer such that a 5 percent by weight emulsion of the composition in deionized water has a pH ranging from 7 to 11.
