Description

Methylestersulfonate C12-C18, Na-Salze is a high-purity anionic surfactant derived from natural fatty acid methyl esters. This compound is valued for its excellent wetting, emulsifying, and dispersing properties, making it a versatile and effective ingredient in demanding formulations. It is primarily required by manufacturers in the detergent, personal care, textile, and industrial cleaning sectors seeking high-performance, biodegradable surfactant solutions.

Application

• Detergent & Cleaning Formulations: Acts as a primary surfactant in liquid detergents, dishwashing liquids, and industrial cleaners, providing superior grease-cutting power and foam stability.
• Personal Care Products: Used in shampoos, body washes, and facial cleansers for its mildness and effective cleansing and foaming characteristics.
• Textile Processing: Serves as a wetting agent, emulsifier, and dispersant in scouring, dyeing, and finishing baths for textiles and fibers.
• Industrial Emulsions: Functions as an emulsifier in the production of polymer emulsions, agrochemical formulations, and lubricant additives.
• Hard Surface Cleaners: A key component in formulations for floor cleaners, degreasers, and vehicle wash products due to its high detergency.
• Paint & Coating Additives: Employed as a dispersing agent to stabilize pigments and fillers in aqueous coating systems.
