WebHydrophilic-lipophilic balance. The hydrophilic–lipophilic balance ( HLB) of a surfactant is a measure of its degree of hydrophilicity or lipophilicity, determined by calculating … WebThe HLB number is usually on a scale of 0–20. Lower HLB values are an indication of high oil affinity. A high HLB value, on the other hand, indicates high water-solubility. The method to calculate the HLB value is given by Stauffer (2002) and Ranjith (2002). Table 16.3 indicates the HLB values of common emulsifiers. As the HLB value increases ...

WebUsing the bottle method, prepare 50 ml of an emulsion by shaking equal volumes of olive oil and lime water in a 3 oz. bottle. Determine the type of emulsion formed by performing a dilution test on a 5-10 ml sample of the emulsion, and a dye test. Add 4-5 ml of 4N HCl solution to 25 ml of the emulsion and record any changes observed. WebThe coconut and sunflower oil blend (70:30, w/w) shows, the required HLB value is 3.7 when it emulsified with 60% of water and found that PGPR + DMG blend gives maximum … WebName:Tayag Merry Jane C.
