| Application of Methyl Ester Sulphonates (MES-Flakes) | Methyl Ester Sulphonates (MES-Flakes) are widely used in laundry detergents, dishwashing formulations, household cleaning products, and industrial cleaners due to their excellent detergency, strong foaming properties, and high biodegradability. Derived from renewable palm-based methyl esters, MES Flakes provide effective stain removal, superior hard water performance, and eco-friendly cleaning solutions. Their sustainable oleochemical origin makes them a preferred alternative to petroleum-based surfactants in modern detergent, personal care, and surface cleaning applications. |
