Description

Sodium 1-Methyl 9-(Sulphooxy)Octadecanoate is a specialized anionic surfactant derived from a modified stearic acid backbone. This compound is valued for its unique combination of hydrophobic and hydrophilic properties, making it an effective emulsifier and wetting agent in demanding formulations. It is primarily utilized by manufacturers in the personal care, industrial cleaning, and textile processing sectors where specific surfactant performance is required.

Application

• Personal Care Formulations: Acts as a primary emulsifier and stabilizer in creams, lotions, and other cosmetic products.
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, metal cleaning formulations, and hard surface cleaners for its wetting and emulsifying power.
• Textile Processing: Serves as a wetting agent, scouring aid, and emulsifier in fiber treatment and dyeing processes.
• Agricultural Adjuvants: Incorporated into pesticide and herbicide formulations to enhance spreading and adhesion on plant surfaces.
• Leather Processing: Functions as a fatliquoring agent and emulsifier in leather tanning and finishing.
• Oilfield Chemicals: Potential use in drilling mud formulations and as a component in demulsifiers.
