A HLB value of 4 3 (pure Span 80) represents an oleophilic surfactant whereas a HLB value of 15 (pure Tween 80) represents a hydrophilic surfactant We also used Tween 85 (HLB=11) 50wt% Tween 85 – 50 wt% Tween 80 (HLB=13) and Tween 40 (HLB=15 8) to show the effect of different surfactants on S2 nanoemulsion formation Nanoemulsion droplet size measurement: Nanoemulsion droplet sizes were

Using mixed nonionic surfactants Span/Tween we investigated the effects of HLB value on the O/W emulsion stability and rheological behaviors In this study MS-01(Span 60 Tween 60) and MS-02(Span 80 Tween 80) was used as mixed nonionic surfactants We considered required HLB value 10 85 and selected corresponding HLB value range 8 to 13 The droplet size distributions droplet morphology

Tween() 80 and five blends of Tween() 80/Span() 80 and Tween() 80/Span() 85 in the hydrophilic-lipophilic balance (HLB) value range of 10 7-14 0 were selected to study the phase diagram behavior of palm kernel oil esters using the water titration method at room temperature RESULTS: High solubilization capacity was obtained by Tween() 80 compared with other surfactants of Tween

The aim of this work was to investigate the phase behaviour and the structure of the n-hexane/water emulsions based on a nonionic nontoxic and biocompatible surfactant Tween 80 This system is of interest for new pharmaceutical techniques based on supercritical fluids to form nano- and encapsulated particles However it showed a lack of stability denoted by large areas of macroemulsion

Span 20 (HLB 8 6) and Span 80 (HLB 4 3) are laureate and stearate sorbitan fatty acid esters respectively Tween 85 (HLB 11 0) is an (ethoxy) 20 sorbitan trioleate ester while Tween 80 (HLB 15 6) is the monooleate ester The Tergitol Span Tween AOT and sodium dodecyl sulfate surfactants were purchased from Sigma Chemical Co St Louis

The HLB value of Span 85 is 1 8 Span 80 is 4 3 and Span 20 is 8 6 while those of Tween 85 and Tween 80 are 11 and 15 The efficiency of a surfactant is not determined solely by the amphilicity it also depends on the HLB characterictics for this compound [10] The mixing of oil water and surfactant in different ratio is able to produce different types of emulsion systems They depend on the

The HLB value varies from 0 to 40 HLB values below 7 indicate emulsifiers that are more soluble in oil and HLB values above 7 indicate emulsifiers that are more soluble in water If a suitable emulsifier is to be chosen for the preparation of a stable emulsion the required HLB value for the lipophilic component and the desired emulsion type should be considered Where several lipophilic

The surfactant's physicochemical behavior of polysorbate 80 such as the hydrophilic lipophilic balance (HLB) or the critical micell concentration (CMC) value is dependent upon its chemical composition governed by the structure of the sorbitol derivative core (i e sorbitan and isosorbide) the degree of esterification the number of POE groups and their distribution within the molecule
