Synergism and Performance Optimization in Liquid Detergents Containing Binary Mixtures of Anionic–Nonionic, and Anionic–Cationic Surfactants

Abstract

In this paper evaluation of surface active and application properties in liquid detergent formulations containing binary mixtures of anionic–nonionic, and anionic–cationic surfactants is discussed. Surfactants used include: linear alkylbenzene sulfonate (LAS), alcohol ether sulfate (AES‐2EO), alcohol ethoxylate (AE‐7EO), lauryl dimethyl amine oxide, and alkyl hydroxyethyl dimethyl ammonium chloride (AHDAC). Surface active parameters relating to the effectiveness and efficiency of surface tension reduction were determined from the surface tension data. Non‐ideal solution theory was used to determine the degree of interactions between the two surfactants, and the conditions under which a mixture of two surfactants show synergism in surface active properties. Our data indicated that synergism in mixed surfactants increases with the degree of charge difference between the surfactants. In both mixed micelle and mixed monolayer formation, the degree of interactions between the two surfactants in the mixture increased in the following order: LAS/AE < AES‐2EO/amine oxide < AES‐2EO/AHDAC. This synergistic behavior as presented in this paper leads to unique application properties and improved performance in terms of foam volume, and soil removal which has applications in formulation of dishwashing liquids, and laundry detergents.

Detergency of Vegetable Oils and Semi‐Solid Fats Using Microemulsion Mixtures of Anionic Extended Surfactants: The HLD Concept and Cold Water Applications

“…2. It can be seen that mixture of these anionic surfactants showed synergism in detergency performance compared to using a single surfactant which is consistent with the literature [40]. More than 90 % canola oil detergency efficiency could be achieved using surfactant mixtures as compared to 68 % using SDOSS alone or 85 % using C 10 -18PO-2EO-NaSO 4 alone.…”

Synthesis and Application of Palm Fatty Acid Distillate Based Alkyd Resin in Liquid Detergent

“…As shown in Table 9, the results of detergency of PFAD-AR liquid detergent formulations were comparable with those of CLD and PO-AR-based liquid detergent formulations at 0.1, 0.25 and 0.5% concentration. LD 5 and LD 4 show better percentage detergency as compared to LD 1 , LD 2 , LD 3 and LD 6 of PFAD-AR-based liquid detergent formulations. In this study, presence of alkyd resin along with SLS/SLES not only enhances the cleaning power but also increases the efficiency of detergents which helps in soil removal.…”

Surface Properties and Solubility Enhancement of Anionic/Nonionic Surfactant Mixtures Based on Sulfonate Gemini Surfactants

“…Surfactant mixture systems include the mixtures of the same types of surfactant compositions and different types of surfactant compositions (Jadidi et al, ; Zhang et al, ; Zheng et al, ). The former surfactant mixtures can be divided into cationic/cationic mixture (Patel et al, ), anionic/anionic mixtures (Szymczyk and Jańczuk, ), and nonionic/nonionic mixtures (Szymczyk and Jańczuk, ), while the latter ones mainly consist of cationic/nonionic mixtures (Fatma et al, ), anionic/nonionic mixtures (Tucker et al, ), anionic/zwitterionic mixtures (Maneedaeng and Flood, ), anionic‐nonionic/nonionic mixtures (Liu et al, ), and anionic/cationic mixtures (Li et al, ).…”
