Sulfoxidation of fatty acid methyl esters with SO 2 , O 2 , and ultraviolet light of appropriate wavelength has led to the synthesis of methyl esters sulfonates or sulfoxylates known as Φ‐MES because of the possible random position of SO 3 group in the alkyl chain. This work describes experimental measurements of physical properties such as solubility and viscosity of sodium Φ‐MES water solutions. Amphipathic properties such as surface tension, critical micelle concentration, wetting and foaming powers were measured as well and compared to linear alkylbenzene sodium sulfonate (LAS). Finally, stability to water hardness, dishwashing test, and detergency performance were evaluated. Expectedly, these products may be used as LAS partners either in heavy‐duty powders or in hand dishwashing liquids. Experimental results on Φ‐MES of varying carbon number indicate that C 16 is the optimal carbon chain length.
