Abstract

The qualitative similarities in two various methods of the HLB (Hydrophile‐Lipophile Balance) determination based on the cloud point and so called phenol index measurements are demonstrated. The effects of polyoxyethylene chain length, surfactant concentration and the presence of additives on the cloud point and phenol index values have been compared. The results are interpreted as the change of the effective HLB of polyoxyethylene nonionic surfactants.

The surface-chemical properties, critical micelle concentrations (CMC), and effect of salts on the cloud points (CP) of octoxynol 9 (Triton X-100) and tyloxapol (Triton WR-1339) were compared. The latter nonionic surfactant is essentially a heptamer of the former. Even though the molecular weight of
