The effect of some common anionic surfactants, namely LABS‐Na, AOS‐Na, SLS, SLES, di‐octyl sulphosuccinate and sodium soaps of coconut, palm and rice bran oils on the cloud point of poly(nona‐)oxyethylene nonylphenol has been determined. It is observed that sodium soaps have a larger effect on the cloud point than do anionic surfactants containing sulphate/sulphonate head groups. The influence on cloud point was found to decrease with an increase in hydrophobic chain length.
