Description

Poly(Oxymethyl-1,2-Ethandiyl), α-Hydro-ω-Hydroxy-Mono(Dihydrogen 2-Hydroxy-1,2,3-Propantricarboxylat), C12-C18-Alkylether, (Mittlerer Eo 16 Mol) is a high-performance, non-ionic surfactant and emulsifier derived from citric acid and fatty alcohol ethoxylates. This specialized chemical is engineered to provide exceptional emulsification, dispersion, and solubilization properties while offering enhanced environmental and skin compatibility profiles. It is a critical ingredient for formulators in the personal care, home care, and industrial cleaning sectors seeking effective, multifunctional, and more sustainable surfactant solutions.

Application

• Personal Care Formulations: Acts as a primary emulsifier and solubilizer in skin creams, lotions, sunscreens, and makeup removers, offering mildness and good skin feel.
• Household & Industrial Cleaners: Provides powerful emulsification and grease-cutting action in hard surface cleaners, degreasers, and laundry detergents.
• Agricultural Adjuvants: Used as a wetting agent, emulsifier, or dispersant in pesticide and herbicide formulations to improve spray coverage and efficacy.
• Textile Processing: Serves as a scouring agent, emulsifier, and lubricant in fiber and fabric treatment processes.
• Paints & Coatings: Functions as a pigment dispersant and grinding aid to improve color development and stability in water-based systems.
• Metalworking Fluids: Employed as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic coolants and lubricants.

Quality Control

Our production of this citric acid ester surfactant adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as ester content, hydroxyl value, acid value, and ethoxylate distribution are monitored using advanced analytical techniques including HPLC, GPC, and titration methods. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and conformance to agreed specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product performance.
