Glycerol Behenate
Overview
Glyceryl Behenate is a fatty acid ester formed from glycerin and behenic acid. It is widely used in pharmaceuticals, cosmetics, and food industries due to its excellent emulsifying and stabilizing properties. The compound is non-toxic, biodegradable, and hypoallergenic, making it suitable for sensitive applications such as baby products and medical formulations. Its versatility stems from its ability to act as a thickening agent, emollient, and release modifier. Glyceryl Behenate is particularly valued in tablet coatings and controlled-release drug formulations, where it ensures uniform drug distribution and enhances bioavailability.
Physical and Chemical Properties
Glyceryl Behenate appears as a white to off-white powder or flakes with a mild odor. It has a melting point range of 65-75°C and is insoluble in water but soluble in organic solvents like ethanol and chloroform. The compound exhibits low hygroscopicity, making it stable under normal storage conditions. Its molecular weight is 414.67 g/mol, and it has a density of approximately 0.95 g/cm³. These properties contribute to its effectiveness as an emulsifier and stabilizer in various formulations. The compound's stability under high temperatures and pH variations further enhances its utility in industrial applications.
Main Applications
In the pharmaceutical industry, Glyceryl Behenate is primarily used as a tablet coating agent and in controlled-release drug delivery systems. It improves the dissolution profile of active pharmaceutical ingredients (APIs) and ensures consistent drug release. The cosmetics industry utilizes it as an emollient and thickening agent in creams, lotions, and ointments. Its hypoallergenic properties make it ideal for sensitive skin products. In the food industry, it serves as an emulsifier and stabilizer, enhancing texture and shelf life in processed foods.
Safety and Storage
Glyceryl Behenate is generally recognized as safe (GRAS) for use in pharmaceuticals, cosmetics, and food. However, it is advisable to avoid inhalation of dust and direct contact with eyes. Proper storage conditions include a cool, dry place away from direct sunlight and moisture to maintain its stability. In case of accidental exposure, rinse thoroughly with water. The compound is biodegradable and poses minimal environmental risk. Always refer to the material safety data sheet (MSDS) for detailed handling and disposal guidelines.
B2B Procurement Guide
When procuring Glyceryl Behenate, verify the CAS number (30233-64-8) and purity specifications to ensure product quality. Supplier certifications, such as ISO or GMP compliance, are critical for pharmaceutical and food-grade applications. Bulk purchases typically offer cost advantages, with prices ranging approximately $20-$50 per kg depending on purity and quantity. Consider sourcing from reputable manufacturers with a track record of consistent quality. Request samples for testing before large-scale procurement to confirm suitability for your application.
