Other dispersion enhancing species include nonionic surfactants such as SPAN 20 (sorbitan monolaurate), SPAN 60 (sorbitan monostearate), SPAN 80 (sorbitan monolaurate), SPAN 85 (sorbitan trioleate), mixtures thereof and the like, as well as OLOA (polyisobutylenesuccinimide), or other anionic surfactants such as SDS (sodium dodecyl sulfate) or SDBS (sodium dodecylbenzene sulfonate).
