Understanding MES

What is Methyl Ester Sulfonate (MES)?

Methyl Ester Sulfonate is a bio-based anionic surfactant produced by sulfonating methyl esters derived from renewable palm or palm-kernel oil feedstock. Widely regarded as a next-generation alternative to petrochemical surfactants like LABSA, MES combines strong detergency with meaningfully better environmental credentials, making it the surfactant of choice for forward-looking detergent manufacturers.
