<p><P>PROBLEM TO BE SOLVED: To provide a dispersant for suitably dispersing wax and other contaminants, in the process of recycling wax coated fibers. <P>SOLUTION: A contaminant dispersant composition comprises water, a plasticizer, an anionic dispersant, a surfactant wetting agent and either (1) an acid or lecithin and optionally, a base, or (2) a preneutralized component. In particular, the plasticizer is 2,2,4-trimethyl-1,3-pentanediol isobutyrate; the anionic dispersant is sodium salt of naphthalene sulfonate; and the surfactant wetting agent is EO/PO block copolymers. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
