Studies on the Detergency of Nonionic Surfactant. III

Effect of the Surfactant's Sorption by Wool Fabrics

Abstract

In this paper, polyoxyethylene nonylphenyl ether EO 10 mol (PEG-N₁₀) and dodecyl benzene sulfonate (Na-DBS) were investigated on the relationship of detergency and quantity of surface active agent absorbed by fabric.
It was found that there was a close relationship between quantity of surface active agent absorbed and whiteness retention with wool, and the reason why PEG-N₁₀ is somewhat inferior to Na-DBS in maximum detergency is justifiable because of its lower whitenness retention.
