Characterization of Microemulsion Systems Formed by a Mixed 1,3‐Dioxolane Ethoxylate/Octyl Glucoside Surfactant System

Abstract

The phase behavior of microemulsion systems containing water (or 1.0 wt% NaCl aq ), isooctane, and the binary surfactant system consisting of n-octyl-b-D-glucopyranoside, C 8 bG 1 , and the acid-cleavable alkyl ethoxylate, 4-CH 3 O (CH 2 CH 2 O) 7.2 , 2-(CH 2 ) 12 CH 3 , 2-(CH 2 )CH 3 ,

Partitioning behavior of an acid-cleavable, 1,3-dioxolane alkyl ethoxylate, surfactant in single and binary surfactant mixtures for 2- and 3-phase microemulsion systems according to ethoxylate head group size

“…2C. The conditions employed produce W III systems, except at 50°C, which resulted in a W II system, in agreement with phase diagrams reported by our group [22]. The middle phase volume fraction for the system formed at 40°C was quite small.…”

“…One such binary system is CK-2,13-E 5.6,ave /alkyl b-glucoside (C8bG1), which readily forms temperature-insensitive microemulsions phases with potential applicability to drug delivery [22]. Temperatureinsensitive microemulsions were also reported for the water/ C10bG1/C 6 E 2 /n-octane system when an equal mass of each surfactant was employed [23,24].…”

The Use of Biobased Surfactant Obtained by Enzymatic Syntheses for Wax Deposition Inhibition and Drag Reduction in Crude Oil Pipelines

“…It has been shown that a biobased surfactant synthesized by the enzyme-catalysed method can enhance oil recovery by interfacial activity and reverse wetting of reservoir rocks [29]. The viability of this method will be improved by further development of more stable and active biocatalysts and new technology in the bioprocessing field [30].…”
