Description

(Sulfooxy)-Octadecanoic Acid Sodium Salt is a specialized anionic surfactant and sulfated fatty acid derivative. This compound is valued for its ability to act as a wetting agent, emulsifier, and detergent in demanding formulations. It is primarily needed by manufacturers in the industrial cleaning, textile processing, and specialty chemical synthesis sectors for its unique surface-active properties.

Application

• As a key surfactant in industrial and institutional (I&I) cleaning formulations, including heavy-duty degreasers and alkaline cleaners.
• Utilized as an emulsifying and wetting agent in textile processing aids, such as scouring and dyeing assistants.
• Acts as a specialty co-emulsifier or stabilizer in the production of polymer emulsions and latex.
• Employed in the synthesis of intermediate chemicals for further functionalization in organic chemistry.
• Serves as a dispersing agent in pigment preparations and agrochemical formulations.
• Potential use in personal care product research for creating specialized anionic surfactant blends.
