Description

Butanedioic Acid,Mono [2-[2-[2-(2-Hydroxyethoxy)Ethoxy]Ethoxy]Ethyl] Ester is a specialized polyether-modified succinate ester, a versatile chemical intermediate designed for advanced formulation chemistry. This compound matters for its unique ability to act as a reactive surfactant or a building block, imparting hydrophilicity and functionality to polymers and surface-active agents. It is primarily needed by manufacturers in the polymer, personal care, and specialty chemical industries seeking to create water-soluble or self-emulsifying products with enhanced performance characteristics.

Application

• Polymer Modification: Used as a reactive monomer or chain transfer agent in the synthesis of water-soluble resins, polyesters, and polyurethanes.
• Surfactant Intermediate: Serves as a key precursor for manufacturing non-ionic and anionic surfactants with low irritation profiles.
• Personal Care Formulations: Employed in the production of emulsifiers and solubilizers for creams, lotions, and color cosmetics.
• Pharmaceutical Excipients: Acts as a solubilizing agent or a component in drug delivery systems for poorly soluble active ingredients.
• Industrial Dispersants: Functions as a grinding aid or dispersing agent in pigment, dye, and agrochemical formulations.
• Coating Additives: Incorporated into water-based coatings and inks to improve flow, leveling, and substrate wetting.
