Description

C16 E8 CAS NO 5698-39-5 is a high-purity, non-ionic surfactant belonging to the polyoxyethylene alkyl ether family, specifically a hexadecyl alcohol ethoxylate. This compound is valued for its excellent emulsifying, wetting, and dispersing properties in aqueous systems. It is a critical raw material for formulators in the agrochemical, personal care, and industrial cleaning sectors who require consistent performance and reliable supply chain partners.

Application

• Agrochemical Formulations: Acts as a key emulsifier and wetting agent in pesticide and herbicide concentrates (ECs, SCs) to enhance spray coverage and biological efficacy.
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, metal cleaning formulations, and textile processing aids for its robust detergency and oil emulsification.
• Personal Care & Cosmetics: Serves as a mild surfactant and emulsifier in cream rinses, lotions, and other rinse-off products where a balance of mildness and performance is needed.
• Paints & Coatings: Functions as a pigment dispersant and grinding aid in water-based systems to improve color development and stability.
• Textile Processing: Employed as a scouring and wetting agent to prepare fibers for dyeing and finishing operations.
• Emulsion Polymerization: Used as a primary or secondary emulsifier in the production of latex polymers, such as acrylics and styrene-butadiene.

Quality Control

Our C16 E8 is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for critical parameters such as hydroxyl value, ethylene oxide content, and cloud point. Certificates of Analysis (COA) documenting purity, identity, and performance characteristics are provided with each shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 can affect product performance.
