Overview
Dipalmitoyl, also known as 1,2-Dipalmitoyl-sn-glycero-3-phosphocholine (DPPC), is a phospholipid widely used in various industries. It is a key component in liposomal drug delivery systems and is valued for its emulsifying and stabilizing properties. Its molecular structure allows it to form bilayers, making it essential in creating liposomes for targeted drug delivery. In addition to pharmaceuticals, dipalmitoyl finds applications in cosmetics, where it acts as a moisturizer and stabilizer. Its ability to enhance the texture and shelf life of products makes it a popular choice in skincare formulations. The compound is also used in the food industry as an emulsifier, though this application is less common compared to its pharmaceutical and cosmetic uses.
Physical and Chemical Properties
Dipalmitoyl appears as a white to off-white powder with a melting point of approximately 41-45°C. It is soluble in organic solvents like chloroform, methanol, and ethanol but insoluble in water. This solubility profile makes it suitable for formulations requiring lipid-based carriers. The compound's molecular weight is 734.03 g/mol, and its stability under recommended storage conditions ensures a long shelf life. Its high purity is critical for applications in pharmaceuticals, where impurities can affect efficacy and safety. The phospholipid nature of dipalmitoyl allows it to form stable bilayers, which are crucial for drug delivery systems.
Main Applications
Dipalmitoyl is primarily used in the pharmaceutical industry as a key component in liposomal drug delivery systems. Its ability to form bilayers makes it ideal for encapsulating drugs, ensuring targeted delivery and improved bioavailability. This application is particularly valuable in cancer therapies and vaccines. In the cosmetics industry, dipalmitoyl serves as a moisturizer and stabilizer, enhancing the texture and longevity of skincare products. Its emulsifying properties are also leveraged in the food industry, though to a lesser extent. The compound's versatility and safety profile make it a preferred choice across multiple sectors.
Safety and Storage
Dipalmitoyl should be handled with care to avoid inhalation or contact with skin and eyes. Proper personal protective equipment (PPE), such as gloves and goggles, is recommended when working with this compound. In case of exposure, rinse thoroughly with water and seek medical attention if necessary. Storage conditions are critical to maintaining the compound's stability. It should be kept in a cool, dry place away from direct sunlight and moisture. Properly sealed containers are essential to prevent degradation. Suppliers typically provide guidelines for optimal storage, which should be followed to ensure product integrity.
B2B Procurement Guide
When procuring dipalmitoyl, B2B buyers should prioritize suppliers who provide a Certificate of Analysis (COA) to verify purity and quality. Compliance with industry standards, such as Good Manufacturing Practices (GMP), is also crucial. Buyers should assess the supplier's reputation, delivery timelines, and customer support. Price ranges vary based on purity and quantity, typically ranging from $50 to $200 per kilogram. Bulk purchases may attract discounts, but buyers should ensure that storage capabilities align with the product's requirements. Establishing long-term relationships with reliable suppliers can ensure consistent quality and timely deliveries.
