Polypropylene oxides conversely, may be inserted to increase the lipophilic character of a surfactant. WebThe cloud point of an alcohol ethoxylate is controlled by the HLB related to its molecular structure. The changes in the cloud point by the alkyl and EO chains are summarized in Table 24.11. 30–32 An increase in the alkyl chain length and a decrease in the EO chain length reduce the HLB, therefore, the cloud point is lowered. This means that the cloud …
