WebbLipophilicity of the compound is low below pH 12 when the majority of the compound exists in an ionized form. In fact, the conclusion we draw from predicting the logD profile of 5-methoxy-2-(1-piperidin-4-ylpropyl)pyridine is contradictory to that derived from examination of logP alone. Negative values of logD (-1.44 to 0) in the physiologically Webbsystem consisting of suitable high (swellants) and medium to low HLB emulsifiers (gellants). It was found that Sisterna® sucrose esters with high HLB values can be used as the swellant and those with medium HLB values as the gellant in LLC emulsions.

Tweens, which are polyoxyethylene derivatives of spans, are hydrophilic and have high HLB values (9.6-16.7).

WebbThus, the HLB values are generally in the range of 0.5–19.5. Nevertheless, the HLB values of ionic surfactants are provided in the literature as an indication of their relative hydrophilicity. Some HLB values are listed in Table 10.2. Thus, an ionic surfactant with an HLB value of 40 simply indicates that it is highly hydrophilic. 5. WebbIn addition, at a certain ratio of high HLB surfactant to low HLB surfactant the viscosity of the LGN emulsion can be tuned by changing the total surfactant level. This offers …
