Fundamental interfacial properties of alkyl-branched sulfate and ethoxy sulfate surfactants derived from Guerbet alcohols. 1. Surface and instantaneous interfacial tensions

摘要: Guerbet surfactants are a unique class of amphiphiles in which the carbon atom β to head group carries an alkyl substituent. A variety sulfate and monodisperse ethoxy were synthesized, their interfacial properties determined at air-water decane-water interfaces determine how branching influences
