Description

Polyoxyethylene 10 Lauryl Ether is a nonionic surfactant belonging to the polyoxyethylene alkyl ether (Brij) family, characterized by a hydrophilic polyethylene oxide chain and a hydrophobic lauryl (C12) tail. This amphiphilic structure provides excellent emulsifying, wetting, and dispersing properties, making it a versatile workhorse in numerous industrial formulations. It is essential for manufacturers in the personal care, pharmaceutical, agrochemical, and textile industries seeking reliable and effective surface-active agents.

Application

• Personal Care & Cosmetics: A key emulsifier and solubilizer in creams, lotions, shampoos, and bath products, helping to blend oil and water phases and stabilize fragrances.
• Pharmaceuticals: Used as an emulsifying agent in topical ointments and creams, and as a solubilizer for poorly water-soluble active pharmaceutical ingredients (APIs).
• Agrochemical Formulations: Acts as a wetting agent, dispersant, and emulsifier in pesticides, herbicides, and foliar sprays to enhance coverage and efficacy.
• Textile Processing: Employed as a scouring, wetting, and leveling agent in dyeing and finishing processes to ensure uniform color application.
• Industrial & Institutional Cleaning: Serves as a primary surfactant in liquid detergents, degreasers, and hard surface cleaners due to its effective grease-cutting and foaming properties.
• Paints & Coatings: Functions as a pigment dispersant and grinding aid to improve color consistency and stability in aqueous-based systems.

Quality Control

Our Polyoxyethylene 10 Lauryl Ether is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for critical parameters such as hydroxyl value, ethylene oxide content, and cloud point. A comprehensive Certificate of Analysis (COA) is provided with every shipment, documenting purity and conformance to agreed standards. We support compliance with relevant frameworks including REACH and can provide material tailored to meet specific pharmacopeial (e.g., USP/NF) or cosmetic grade requirements upon request.

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); ensure containers are sealed after each use to prevent absorption of atmospheric moisture, which can affect product performance.
