The Complex of Sodium Dodecylbenzenesulfonate and Cationic Cellulose Polymer solubilizing oil-soluble Dye

Abstract

Sodium dodecylbenzenesulfonate (NaDBS) and NaDBS solubilizing yellow OB (YOB) in the aqueous solution were precipitated by addition of cationic cellulose polymer (CCP).
The molar ratio of DBS in the dried matrix of the complex thus precipitated was 1.0. Both DBS in the above-mentioned complex without YOB, and YOB in the complex solubilizing the dye were readily extractable with ethyl alcohol, but hardly with n-hexane and benzene. From these results it is speculated that YOB is solubilized in the complex of DBS-CCP, and released from the complex along with the release of DBS.
