Description

Propanoic Acid, 2-Hydroxy-, Polymer With .Alpha.,.Alpha.'-[(Octadecylimino)Di-2,1- Ethanediyl]Bis[.Omega.-Hydroxypoly(Oxy-1,2-Ethanediyl)] is a high-performance, non-ionic polymeric surfactant derived from lactic acid and stearyl amine ethoxylates. This advanced copolymer is engineered to provide exceptional emulsification, stabilization, and surface-modifying properties in complex formulations. It is a critical additive for industries requiring robust, multi-functional performance in personal care, coatings, and industrial applications where compatibility and long-term stability are paramount.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and stabilizer in creams, lotions, sunscreens, and color cosmetics, providing a smooth texture and enhancing product shelf life.
• Coatings & Inks: Functions as a dispersing agent and flow aid in water-based and solvent-based coating systems, improving pigment wetting and film formation.
• Industrial Cleaners & Detergents: Used as a surfactant and coupling agent in hard surface cleaners and industrial degreasers for effective soil removal and emulsion stability.
• Agrochemical Formulations: Serves as an emulsifier and adjuvant in pesticide and herbicide concentrates, aiding in the dispersion of active ingredients.
• Textile & Leather Processing: Employed as a softening agent, lubricant, and dyeing auxiliary to improve handle and processing efficiency.
• Polymer & Resin Modification: Utilized as an internal or external additive to modify surface properties, improve compatibility, and reduce viscosity in polymer blends.
