Overview
Glyceryl dioleate is a fatty acid ester derived from glycerol and oleic acid. It is widely used in various industries due to its emulsifying and lubricating properties. The compound is non-toxic and generally recognized as safe for use in food and cosmetic products. Glyceryl dioleate is commonly found in food additives, where it acts as an emulsifier to improve texture and shelf life. In cosmetics, it serves as a moisturizing agent and emollient, providing smoothness to skin and hair products.
Physical and Chemical Properties
Glyceryl dioleate is a pale yellow to amber oily liquid with a density of approximately 0.92 g/cm³. It is soluble in organic solvents but insoluble in water, making it suitable for oil-based formulations. The compound exhibits excellent emulsifying properties, which are essential for stabilizing mixtures of oil and water. Its molecular weight is 620.99 g/mol, and it is stable under normal storage conditions. Glyceryl dioleate is non-volatile and has a low reactivity, making it safe for use in various applications without significant degradation.
Main Applications
In the food industry, glyceryl dioleate is used as an emulsifier in products like margarine, baked goods, and processed foods. It helps maintain consistency and prevents separation of ingredients. The compound is also used in cosmetics, where it acts as a skin-conditioning agent and emollient. Industrial applications include its use as a lubricant in metalworking and textile manufacturing. Its non-toxic nature makes it suitable for use in pharmaceutical formulations, where it serves as a solubilizing agent for poorly water-soluble drugs.
Safety and Storage
Glyceryl dioleate is generally recognized as safe (GRAS) for food use by regulatory authorities. However, it should be handled with care to avoid eye contact or prolonged skin exposure. Proper storage involves keeping the compound in a cool, dry place away from direct sunlight to prevent degradation. For industrial use, standard safety measures such as wearing gloves and eye protection are recommended. The compound is not classified as hazardous, but spills should be cleaned promptly to avoid slipping hazards.
B2B Procurement Guide
When procuring glyceryl dioleate, buyers should verify the CAS number (25637-84-7) to ensure product authenticity. Purity specifications should be checked, especially for food-grade or pharmaceutical-grade applications. Suppliers with certifications like ISO or GMP are preferred for quality assurance. Price ranges vary depending on purity and supplier, with food-grade versions typically costing more. Bulk purchases may offer cost savings, but storage conditions must be adequate to maintain product integrity. Request samples for testing before large-scale procurement.
