WebHLB value of Tween 80: 15 HLB value of Span 80 : 4.3 The water and oil phases are heated in separate vessels to 70-72°C on a water bath. The water phase is added to the oil phase slowly and it is stirred continuously. Continue stirring until the temperature reaches to room temperature. Questions: 1. Describe what the HLB value is. 2. WebHLB Values. The HLB value can be used to predict the surfactant properties of a molecule: < 10 : Lipid soluble (water insoluble) > 10 : Water soluble (lipid insoluble) 1.5 to 3: anti-foaming agent. 3 to 6: W/O (water in oil) emulsifier. 7 to 9: wetting and spreading agent. 13 to 15: detergent.

WebJan 11, 2024 · The HLB of the algae-derived mixed 1000 PEG surfactant was the same as phytol, which came in just above standard #4, having an HLB value of 9.65. This indicates that a water-oil emulsifier that is water-soluble was produced with reasonable detergency. WebIf an emulsifier with a particular HLB value stabilizes an emulsion with a certain type of oil, then another emulsifier with the same HLB number generally has the same emulsifying … brownfield land release fund ope

WebThe lowest turbidity value for R. officinalis emulsion was obtained at HLB 16.5 (0.33) and corroborates the required HLB found using the droplet size for this oil. The turbidity value obtained for different HLB of I. verum emulsions showed no significant difference (ANOVA, p>0.05) and could not be used to identify the required HLB of this oil ... WebHLB, the so-called Hydrophile - Lipophile Balance, is the ratio of oil soluble and water-soluble portions of a molecule. The system was originally developed for ethoxylated products. Listed in Table 1 are some approximations for the HLB value for surfactants as a function of their solubility in water. Values are assigned WebApr 26, 2002 · The HLB value of the emulsion with the least dispersion ratio or the least percentage increase in mean droplet diameter was taken as the required HLB of the … brownfield land uk
