Custom Manufacturing, Project Outsourcing, your Trusted Partner from China
For professionals in the chemical industry, especially procurement managers and R&D scientists, a deep understanding of product specifications is crucial for making informed purchasing decisions. Hydroxypropyl-Beta-Cyclodextrin (HPBCD) is a complex molecule with varying grades and specifications tailored for different applications. As a leading manufacturer and supplier of HPBCD in China, we aim to provide clarity on these critical parameters, ensuring our clients receive a product that perfectly matches their needs. Navigating these specifications is the first step to successfully buy HPBCD.
Key specifications for HPBCD typically include its appearance, content (purity), degree of substitution, loss on drying, and levels of specific impurities like propylene oxide and heavy metals. The 'Appearance' usually refers to a white crystalline powder, indicating its physical state. 'Content' or purity, commonly assayed at ≥98%, is a primary indicator of quality and is vital for demanding applications like pharmaceuticals. The 'Degree of Substitution' (DS) refers to the average number of hydroxypropyl groups per cyclodextrin molecule, which can influence its solubility and complexation properties, often ranging from 3 to 10 for standard grades.
'Loss on Drying' indicates the moisture content, usually specified as ≤10.0%, which is important for storage stability and accurate weighing. Strict limits on impurities such as 'Propylene Oxide' (often ≤1ppm) and 'Heavy Metals' (e.g., ≤20ppm) are critical, especially for food and pharmaceutical applications, ensuring safety and regulatory compliance. Further parameters like microbial limits are also important for certain uses. Understanding these specifications helps buyers to compare products from different suppliers and select the best fit for their intended application.
When sourcing HPBCD, always verify that the supplier provides comprehensive documentation, including detailed Certificates of Analysis (CoA) for each batch. As a reputable China manufacturer, we meticulously control our production processes to meet these stringent specifications. For chemical buyers looking to procure high-quality HPBCD, we encourage you to contact us to discuss your specific requirements. Our team is ready to provide detailed information and support to ensure you find the optimal HPBCD product for your formulation needs, securing a reliable supply chain.
