For procurement specialists and research scientists in the chemical industry, a deep understanding of a compound's properties is fundamental to making informed purchasing decisions. Potassium Oleate (CAS 143-18-0) is a prime example of a chemical whose well-defined physical and chemical characteristics make it a valuable asset across numerous sectors. As a leading Potassium Oleate supplier in China, we are committed to providing detailed insights into this versatile anionic surfactant.

At its core, Potassium Oleate is the potassium salt of oleic acid, a monounsaturated fatty acid. Its molecular formula, C18H33KO2, and molecular weight of approximately 320.55 g/mol, are critical identifiers for chemical buyers. Physically, it presents as a colorless to palm red silk liquid, though it can also be found as a brown solid or clear to amber liquid depending on purity and processing. This appearance variability necessitates close attention to specification sheets when purchasing.

Key properties such as its solubility and melting point are crucial for application suitability. Potassium Oleate is easily soluble in water, forming clear to slightly opalescent solutions, and also soluble in hot alcohol. Its reported melting point can range significantly, with some sources listing it around 220°C for solid forms, while others describe it as a liquid at room temperature with a boiling point around 360°C. This range underscores the importance of obtaining precise data from a reliable manufacturer. The Hydrophilic-Lipophilic Balance (HLB) value, often around 20, further indicates its strong surfactant and emulsifying capabilities, leaning towards water-soluble applications.

The acid value and iodine value are also important parameters for industrial grade Potassium Oleate. Typical specifications include an acid value between 195-204 and an iodine value of 80-100, reflecting its oleic acid content and degree of unsaturation. Low free alkali content and controlled loss on drying are also critical indicators of quality for discerning buyers. As a trusted Potassium Oleate supplier, we ensure our products meet these stringent specifications, providing confidence to formulators and researchers.

Understanding these scientific underpinnings allows B2B customers to precisely match Potassium Oleate to their application needs, whether it’s for cosmetic formulations, industrial catalysis, or textile treatments. We invite chemical buyers to explore our comprehensive product data, ensuring you can buy Potassium Oleate with full confidence in its quality and performance from our manufacturing facility in China.
