Abstract
Purified polyethylene glycol and nonyl phenol were mixed with distilled polyoxyethylene nonyl phenol ether, and the results were investigated for clouding points, wetting properties and foaming properties of the mixtures.
The result compared with the effect of variation on the distribution of additive oxyethylene mole numbers studied in the previous reports.
Added polyethylene glycol had no effect on clouding points and foaming properties, but had slight effect on wetting properties.
On the other hand, nonyl phenol had no effect on wetting properties, but had remorkable effect on foaming properties and clouding points, and also it had minor effect on the form of the curves, the forming properties plotted against temperature.
As compared with the result of the previous reports, it was believed that the effect on added impurites were greater than the effect of the distribution of additive oxyethylene mole numbers.
