Description

Butynediol Sulfopropyl Ether Sodium is a specialized anionic surfactant and reactive intermediate derived from butynediol. This compound matters for its unique combination of a sulfonate group and an ethoxylated chain, offering excellent water solubility, wetting properties, and chemical reactivity. It is primarily needed by manufacturers in the textile, personal care, and specialty polymer industries for applications requiring high-performance surfactants or cross-linking agents.

Application

• Textile Auxiliaries: Used as a wetting agent, dispersant, and leveling agent in dyeing and printing processes.
• Personal Care Formulations: Serves as a mild surfactant and emulsifier in shampoos, body washes, and other cleansing products.
• Polymer Modification: Acts as a reactive monomer or cross-linker in the synthesis of water-soluble resins and specialty polymers.
• Paper & Pulp Industry: Functions as a dispersant and process aid in paper coating and de-inking operations.
• Industrial Cleaning: Employed in formulations for industrial and institutional (I&I) cleaners due to its surfactant properties.
• Electroplating Additives: Can be used as an additive in electroplating baths to improve surface wetting and coating uniformity.
