Description

Sodium 1-(2-Ethoxyethyl) 10-Hydroxy-9-Sulphonatooctadecanoate is a specialized anionic surfactant derived from octadecanoic acid, featuring a unique combination of a sulfonate group, a hydroxyl group, and an ethoxyethyl ester moiety. This molecular architecture provides excellent emulsifying, wetting, and dispersing properties, making it a valuable component in formulations requiring high performance and stability. It is primarily utilized in demanding industrial applications such as textile processing, agrochemical formulations, and specialty cleaning products where robust surface activity is critical.

Application

• Textile Processing: Acts as a key wetting agent, emulsifier, and dispersant in dyeing and finishing baths for synthetic and natural fibers.
• Agrochemical Formulations: Used as an emulsifier and stabilizer in pesticide and herbicide concentrates to ensure uniform dispersion and efficacy.
• Industrial & Institutional (I&I) Cleaning: Serves as a powerful surfactant in heavy-duty degreasers, metal cleaners, and hard surface cleaners.
• Leather Processing: Functions as a fatliquoring agent and emulsifier in the tanning and finishing stages.
• Paints & Coatings: Employed as a dispersing agent for pigments and fillers to improve color development and stability.
• Oilfield Chemicals: Utilized in drilling mud formulations and as an additive for enhanced oil recovery processes.
• Paper & Pulp Industry: Aids in de-inking processes and acts as a dispersant for pitch control.
• Personal Care (Rinse-off products): Can be used in specialized rinse-off formulations requiring strong cleansing and emulsification.
