A series of s-decyl glucopyranosides was prepared, and surface properties, such as static surface tension, critical micelle concentration (cmc), occupation area of a molecule at surface, dynamic reduction of surface tension and foaming properties, foam suppression in fermentation process using Baker's yeast, biodegradation, and antimicrobial properties were studied and compared with those of n-decyl glucopyranosides. The s-decyl glucopyranosides showed excellent surface properties and biodegradability by environmental microbes compared to n-decyl glucopyranosides. The most prominent characteristics of s-decyl glucopyranosides compared to n-decyl glucopyranosides were the dynamic surface tension reduction and the foaming properties. Dynamic surface tension reduction was faster when the hydrophilic glucopyranosyl group was bonded near the center of the alkyl chain. The same was noted for foam production and stability, s-Alkyl glucopyranosides were confirmed to function as an antifoamers in fermentation.
