“…Environmentally‐friendly surfactants, developed due to the rising focus on sustainable development and the need to overcome the toxicity of conventional surfactants (Rane et al, 2021), are a valuable industrial commodity. These surfactants are typically biodegradable, non‐toxic, and pose less threat to the environment (Hayes, 2019; Kosaric & Vardar‐Sukan, 2014).…”

“…Eco‐friendly surfactants can be differentiated into several categories (according to their molecular structure) such as glycolipids, lipopeptides, alkyl polyglycosides, and polymeric biosurfactants (Hayes, 2019; Ortiz et al, 2022; Rane et al, 2021); the molecular structure of some representative examples are in Figure S1 of the Supplementary Material. Alkyl polyglycosides (APGs) have attracted notable interest, especially in the cosmetics and agrochemical industries, because of their ease of manufacturing (Hill et al, 1996).…”

Eco‐friendly surfactant alkyl polyglycosides (APGs) have garnered ample interest in the literature. However, the adsorption kinetics of APGs at an air‐water interface has not been studied to date. Consequently, this study aimed at investigating the adsorption kinetics of the APG n‐decyl‐β‐D‐maltopyranoside (β‐C10G2) at a freshly created air‐water interface. The dynamic and equilibrium surface tension (ST) of the aqueous β‐C10G2 solutions were experimentally measured at varying concentrations using a pendant bubble tensiometer and the ST data were examined via theoretical simulations using the Langmuir and Frumkin models. The fitting results revealed that the Frumkin model (with K = −2.9) well‐predicted the equilibrium ST data; signifying a considerable cohesive intermolecular force amidst the adsorbed β‐C10G2 molecules. The theoretical mixed‐controlled ST profiles (predicted by the Frumkin model) described the dynamic ST data reasonably well, but the adsorption rate constant increased significantly at increasing concentration. A comparison on the ST data of β‐C10G2 and β‐C12G2 (n‐dodecyl‐β‐D‐maltopyranoside) was also conducted and a relatively greater surface‐activity and lower cmc of the latter alkyl glycoside was observed.
