A series of amide‐linked surfactants from methyl glucoside was synthesized and investigated for their potential use as water‐in‐oil emulsifiers. The synthetic concept combined a nucleophilic substitution approach with a Staudinger coupling of the intermediate azide. Both straight and Guerbet‐type branched fatty acids ranging from C 8 to C 16 were applied. All surfactants exhibited very high Krafft temperatures, which were related to the amide linkage and exclusively formed the hexagonal H 1 ‐phase. The Guerbet C 16 surfactant enabled the formation of a stable water‐in‐oil gel at ambient temperature, which, however, required heating to form the corresponding fluid emulsion.
