For professionals in the chemical and pharmaceutical industries, a thorough understanding of product specifications is critical when making purchasing decisions. Hard Fat, known by CAS number 91744-42-2, is a prime example where detailed specifications dictate its suitability for various applications, primarily as a pharmaceutical excipient. As a leading manufacturer and supplier, we aim to demystify these specifications for our clients.

The primary visual characteristic of Hard Fat is its appearance: typically a white or off-white paraffin solid with a distinctly greasy smell and touch. This physical attribute is the first indicator of quality for potential buyers. Following appearance, the Melting Point is a crucial specification, usually falling within the 35-37°C range. This narrow range ensures predictable behavior during formulation and application, especially in temperature-sensitive processes or products.

Chemical purity and reactivity are assessed through several key values. The Acidity Value, typically specified as ≤1.0mgKOH/g, indicates the concentration of free fatty acids, which can affect formulation stability. The Saponification Value, usually between 215-260mgKOH/g, reflects the ester content. A lower Hydroxyl Value (≤60mgKOH/g) is generally preferred, as it signifies a lower proportion of free glycerol or mono- and diglycerides. The Iodine Value, kept low (≤2.0g/100g), confirms the degree of saturation, crucial for preventing oxidation and rancidity.

Furthermore, specifications such as Peroxide Value (≤3meg/kg), Ash content (≤0.05%), and Heavy Metals (≤10ppm) are critical for pharmaceutical applications, ensuring the absence of degradation products, inorganic impurities, and toxic elements. When you decide to buy Hard Fat, always request a Certificate of Analysis (COA) that details these parameters. As a dedicated manufacturer in China, we ensure our Hard Fat meets these exacting standards, providing confidence to our customers.

For businesses looking to procure Hard Fat, understanding these specifications helps in comparing different suppliers and ensuring you receive a product that perfectly matches your application's requirements. We encourage you to inquire about our competitive Hard Fat price and discuss your specific needs with our team. Partnering with a reliable supplier like us means gaining access to high-quality materials that uphold the integrity of your final products.
