Description

Sodium Oleate CAS NO 143-19-1 is the sodium salt of oleic acid, a key fatty acid derivative widely used as an emulsifier, surfactant, and stabilizer. This versatile compound is essential for creating stable emulsions and modifying surface properties in aqueous systems. It serves as a critical raw material for manufacturers in the personal care, pharmaceutical, textile, and metalworking industries.

Application

• Soap & Detergent Manufacturing: Acts as a primary emulsifying and cleansing agent in bar soaps, liquid soaps, and industrial cleaners.
• Cosmetics & Personal Care: Used as an emulsifier and thickener in creams, lotions, and shaving products to stabilize oil-in-water formulations.
• Textile Processing: Functions as a lubricant, softener, and scouring agent in fiber processing and fabric finishing.
• Metalworking Fluids: Serves as a corrosion inhibitor and emulsifier in soluble oils and cutting fluids.
• Pharmaceuticals: Employed as an emulsifying agent in topical ointments and creams.
• Rubber & Polymer Industry: Acts as a processing aid and mold release agent.
• Food Industry (Food Grade): Used as a binder, emulsifier, and anticaking agent (subject to specific purity grades and regulations).
• Laboratory & Chemical Synthesis: Utilized as a reagent and surfactant in various chemical processes.

Quality Control

Our Sodium Oleate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, acid value, and moisture content are provided with every shipment. We can supply grades compliant with various industry standards, including technical, cosmetic, and food-grade specifications, 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 kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
