PROBLEM TO BE SOLVED: To provide a nonionic surfactant compound obtained by adding an alkylene oxide to an aliphatic alcohol, while improving odor, penetrating, reducing surface tension, detergency, emulsifying, dispersing, and dispersing. To provide a material capable of keeping performance such as solubilizing power sufficiently high. The nonionic surfactant comprises a compound of the general formula (I), and the ratio of the molecular weight to the compound of the general formula (II) having a cloud point approximately equal to that of the compound is 1.05 to 2.00. R-O- (C 2 H 4 O) p - [(C 2 H 4 O) q / (AO) r] -H ยทยทยท (I) R-O- (C 2 H 4 O) a-H ... (II). However, R: a branched aliphatic hydrocarbon group having 8 to 20 carbon atoms, p, q, r: average number of moles added (p = 2 to 10, q = 1 to 15, r = 1 to 4. 5), [(C 2 H 4 O) q / (AO) r]: a random polymerization chain of an oxyethylene group and an oxyalkylene group having 3 or 4 carbon atoms at a molar ratio of q / r. |
