Description

Alcohols, C16-20, Ethoxylated is a nonionic surfactant belonging to the class of fatty alcohol ethoxylates, derived from a blend of C16 to C20 fatty alcohols reacted with ethylene oxide. This compound is valued for its excellent emulsifying, wetting, and dispersing properties, making it a versatile workhorse in industrial formulations. It is essential for manufacturers in sectors such as agrochemicals, textiles, and industrial cleaning, where stable emulsions and surface activity are critical.

Application

• Primary Emulsifier in Agrochemicals: Used in the formulation of pesticide and herbicide concentrates to ensure stable oil-in-water emulsions for effective crop protection.
• Textile Processing Aid: Acts as a scouring, wetting, and leveling agent in dyeing and finishing processes for natural and synthetic fibers.
• Industrial & Institutional (I&I) Cleaning: A key surfactant in heavy-duty degreasers, metal cleaners, and floor care products due to its robust grease-cutting ability.
• Lubricant and Metalworking Fluid Additive: Provides emulsification and surface wetting in soluble oils and synthetic coolants.
• Pulp and Paper Processing: Used as a dispersant and deinking agent in paper recycling and pulp washing operations.
• Intermediate for Sulfation/Sulfonation: Serves as a raw material for producing anionic surfactants like alcohol ether sulfates (AES).
• Emulsion Polymerization: Functions as a stabilizer and emulsifier in the production of synthetic latexes, such as acrylics and styrene-butadiene.

Quality Control

Our Alcohols, C16-20, Ethoxylated is manufactured under a strict quality management system. Each batch is tested against key parameters including hydroxyl value, cloud point, and moisture content to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) detailing the specific ethylene oxide distribution and physical-chemical properties are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at ambient temperatures (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive); keep containers tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
