Reaction Steps

Heating 100 parts (0.33 equivalents) 12-hydroxystearic acid with 64.1 parts (0.23 equivalents) stearylamine and 3.0 parts ethylenediamine (0.1 equivalents) to 220° C. yielded an extended stearyl 12-hydroxystearamide as a hard, opaque wax having an acid number of 7. Treatment of the extended stearyl 12-hydroxystearamide with 27.2 parts (0.33 equivalents) hexamethylene diisocyanate at 150° C. provided hexamethylene diisocyanate-modified stearyl 12-hydroxystearamide as a translucent, hard, light-tan solid having a melting point of 94° C. and a melt viscosity of 110 cP at 130° C.
