Emulsified poly(oxyalkylenated) colorants for wax compositions
摘要:
This invention relates to a dispersions of polymeric colorants having poly(oxyalkylene) moieties mixed with unsubstituted sorbitan monooleate alone or ethoxylated dodecanol admixed with unsubstituted sorbitan monooleate. Such colorant dispersions are easy to handle and are effectively introduced into wax media, thereby providing significant improvements over other dyestuffs, pigments, and colorants.
