When sourcing Potassium Stearate (CAS 593-29-3), understanding its technical specifications is fundamental to ensuring it meets the precise requirements of your application. As a premier manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. believes in empowering our clients with knowledge. This guide delves into the key specifications of Potassium Stearate and why they matter for formulators and procurement managers.

Assay (%): This indicates the purity of the Potassium Stearate. For many applications, particularly in cosmetics and pharmaceuticals, a high assay (e.g., 98% or higher) is critical to ensure product efficacy and safety. Lower assays might be acceptable for certain industrial uses where cost-effectiveness is a primary driver. When you buy Potassium Stearate, always check the assay against your application’s needs.

Appearance (Form and Color): Typically, high-quality Potassium Stearate is a white to off-white powder. Its texture is often described as light, fine, and greasy to the touch. Deviations in color or texture could indicate impurities or degradation, so a consistent appearance is a good initial indicator of quality from a reputable potassium stearate manufacturer.

Acid Value / Acidity (%): These parameters measure the amount of free fatty acids or alkali present. A low acid value or acidity is desirable, as excessive free fatty acids can affect product stability and performance, especially in sensitive formulations like cosmetics and food. Ensuring a low acidity is part of our commitment as a responsible supplier.

Loss on Drying (%): This specification indicates the moisture content. High moisture can affect the product's stability, leading to clumping or potential microbial growth. Manufacturers aim to keep this value low, typically below 5%, to ensure product integrity. This is a crucial parameter when you are looking to purchase Potassium Stearate for long-term storage.

Iodine Value: This measures the degree of unsaturation in the fatty acid chain. Stearic acid is a saturated fatty acid, so a low iodine value is expected and desirable for Potassium Stearate, indicating it is derived from predominantly saturated fats. A higher iodine value might suggest the presence of unsaturated fatty acids, which could impact stability and shelf life.

Heavy Metals and Arsenic: For food-grade and pharmaceutical applications, strict limits are placed on heavy metals (like lead) and arsenic. Manufacturers must conduct rigorous testing to ensure these impurities are well below regulatory thresholds. This commitment to safety is a hallmark of a trustworthy CAS 593-29-3 supplier.
