The objective of this work was to apply a microemulsion-based formulation for the removal of motor oil in laundry detergency at low salinity. To produce the desired phase behavior, three surfactants were used: alkyl diphenyl oxide disulfonate (ADPODS), sodium dioctyl sulfosuccinate (AOT) and sorbitan monooleate (Span 80). The mixed surfactant system of 1.5% ADPODS, 5% AOT and 5% Span 80 (13 parts ADPODS, 43.5 parts AOT, and 43.5 parts Span 80 of the total actives) was found to form a middle phase microemulsion (Type III) at a relatively low salinity of 2.83% NaCl. When this formulation was diluted, detergency performance increased with increasing total surfactant concentration and leveled off above about 0.1% total actives on the three types of fabrics studied (pure cotton, 65/35 polyester/cotton blend, and pure polyester). Detergency was found to improve with increasing hydrophilicity of the fabric with cotton being cleanest after washing and polyester the most difficult to clean. To achieve a specified oil removal, less rinse water can be used if a higher number of lower-volume rinses are employed. An interesting characteristic of microemulsionbased formulations is that a substantial fraction of oil removal occurs during the rinse cycle. In this work, this removal is shown to be due to the low oil/water interfacial tension during initial rinsing and is therefore strongly correlated to residual surfactant concentration in the rinse steps. As a result, the number of rinses and the volume of water per rinse can profoundly affect detergency in these systems.

“…These surfactants, which contain the amide group forming a linkage between the hydrophobic chain and the hydrophilic saccharide moiety, are obtained in a selective reaction of saccharide carboxylic acids or their lactones with alkylamines (7,8). Recently, gel-forming properties (9-13), formation of mono-and bilayers (8,10,12), formation and structure of microemulsion systems containing N -alkylamides (14), as well as aggregation behavior of diastereomeric and enantiomeric Noctylaldonamides (10) have been investigated. Several papers reported on surface-active properties of aqueous solutions of N -alkylgluconamides (9,15), N -alkyllactobionamides (16,17), and N -alkylmaltobionamides (18,19), characterized by surface tension measurements.…”

“…Another aim of this work is to investigate the effect of added monovalent electrolyte on the microemulsion phase behavior of mixed anionic-cationicoil-water systems. Although a number of researchers have evaluated the effect of added electrolyte on the microemulsion phase behavior of ionic surfactants (36)(37)(38)(39), previous research has not evaluated alcohol-free mixed anionic-cationic surfactant systems. Anton et al (20) studied the effect of added monovalent electrolyte on the cationic surfactant fraction in a mixed anionic-cationic surfactant system for an oil-NaCl-alcohol system.…”

This research evaluated middle-phase microemulsion formation by varying the mole ratio of anionic and cationic surfactants in mixtures with four different oils (trichloroethylene, n-hexane, limonene, and n-hexadecane).Mixtures of a double-tailed anionic surfactant (sodium dihexyl sulfosuccinate, SDHS) and an unbalanced-tail (i.e., doubletailed with tails of different length) cationic surfactant (benzethonium chloride, BCl) were able to form microemulsions without alcohol addition. The amount of NaCl required to form the middle-phase microemulsion decreased dramatically as an equimolar anionic-cationic surfactant mixture was approached. Although the mixture of anionic and cationic surfactants demonstrated a higher critical microemulsion concentration (cµc) compared to the anionic surfactant alone, the Winsor Type IV single-phase microemulsion started at lower surfactant concentrations for the anionic-cationic mixture than for the anionic surfactant alone. Under optimum middlephase microemulsion conditions, mixed anionic-cationic surfactant systems solubilized more oil than the anionic surfactant alone. Pretreatment detergency studies were conducted to test the capacity of these mixed surfactant systems to remove oil from fabrics. It was found that anionic-rich mixed surfactant formulations yielded the largest oil removal, followed by cationic-rich systems.
