Synthesis and Surface Activity of Bisphosphate Gemini Surfactants

Abstract

Anionic bisphosphodiester gemini surfactants with two different spacer moieties and varying alkyl chain lengths were synthesized and investigated for their surface active properties. The equilibrium and dynamic surface tension studies were carried out using the Wilhelmy plate technique and maximum bubble pressure method respectively. It was found that these gemini surfactants possess lower critical micellar concentration values, and reduce the surface tension to a greater extent in comparison with the conventional analogues. The efficiency of the synthesized gemini surfactants was also evaluated. The results of surface activities obtained were correlated with the structures of gemini surfactants. The dynamic surface tension measurements showed that the geminis with long chains adsorb very slowly at the air/water interface within the time span of measurements. These gemini surfactants showed low foamability.

Application of Anionic Phosphorus Derivatives of Alkyl Polyglucosides for the Production of Sustainable and Mild Body Wash Cosmetics

“…Numerous scientific publications in this area discuss the synthesis of APG derivatives containing, among others, sulfosuccinate and phosphate groups which give them the characteristics of anionic surfactants and modify their properties to achieve an even more favorable functional profile, for example, as washing compounds in the cosmetics industry (improved detergent and foaming properties). As the literature review shows, studies of anionic derivatives of APGs published to date represent basic research and are mostly limited to describing the synthesis of the compounds and determining their physicochemical properties. − Only a few and scanty reports, mainly collective papers , and patent descriptions, − point to their practical industrial applications; however, there is no detailed information on the functional properties of products in which such APG derivatives would be used.…”

The Effect of Polar Head and Chain Length on the Physicochemical Properties of Micellization and Adsorption of Amino Alcohol‐Based Surfactants

“…Cationic surfactants have attracted the attention of many researchers for a long time because of their wide applications, they are used as softeners, cosmetic or coating ingredients (Akram et al, 2015), antimicrobial agents (Gotmukle and Bhagwat, 2013;Migahed et al, 2016), and also in the mining and papermaking industries (Nilsson et al, 2008).…”

Interaction of Anionic Gemini Surfactants with Other Surfactants

“…[1,2] These surfactants have been found to be superior as compared to conventional surfactants in several properties. [3] In past two decades, gemini surfactants have attracted lot of interest because of their very low CMC values and greater efficiency in reducing the surface tension (ST) compared to conventional surfactants. Gemini surfactants possess excellent solubilization, wetting, specific rheological and aggregation properties.…”
