Description

Oleth-4 is a nonionic surfactant belonging to the polyoxyethylene alkyl ether family, widely recognized for its excellent emulsifying, wetting, and solubilizing properties. This versatile chemical is crucial for formulators seeking to create stable, high-performance products across diverse industrial and consumer sectors. It is particularly valued in the personal care, pharmaceutical, and agrochemical industries for its ability to effectively blend oil and water phases. For precise identification, the compound is registered under CAS No. 5353-26-4.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and solubilizer in creams, lotions, shampoos, and makeup, ensuring smooth texture and stability.
• Pharmaceutical Formulations: Used as an emulsifying agent in topical ointments, creams, and lotions, and as a solubilizer for active pharmaceutical ingredients (APIs).
• Agrochemicals: Serves as a key component in pesticide and herbicide formulations, enhancing the wetting, spreading, and penetration of active ingredients.
• Industrial & Institutional Cleaners: Functions as a surfactant in degreasers, hard surface cleaners, and textile processing aids for effective soil removal and emulsification.
• Metalworking Fluids: Employed as an emulsifier in soluble oils and synthetic coolants to stabilize oil-in-water emulsions.
• Paints & Coatings: Aids in pigment wetting and dispersion, improving the consistency and application properties of water-based coatings.

Quality Control

Our Oleth-4 is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance. While specific grades (e.g., cosmetic, pharmaceutical, technical) are available, all products undergo rigorous analytical testing including assay, hydroxyl value, and cloud point determination. Certificates of Analysis (COA) documenting purity and key physical-chemical parameters are provided with every shipment to support your quality assurance protocols.

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); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
