HLB composition was found to depend on the concentrations of emulsifiers in systems of aqueous/sodium dodecyl sulfate/2 ethylhexylglyceryl ether/aromatic oil. The ratio of lipophilic emulsifier at the HLB composition increased progressively with systems containing aromatic hydrocarbon, alicyclic hydrocarbon and alkane at high emulsifier concentration in this order. This order corresponded to that of HLB temperature in systems of nonionic emulsifiers. In contrast, it increased with systems containing alicyclic hydrocarbon, alkane, aromatic hydrocarbon at low concentration and this finding has practical application. Taking these results into consideration, the monodispersed solubilities of emulsifiers in each oil were examined. |
