Overview
Gamma-Octalactone is a lactone derivative with a sweet, coconut-like aroma, naturally found in some fruits and dairy products. It is widely synthesized for industrial use due to its pleasant scent and stability. As a flavor and fragrance compound, it plays a significant role in enhancing sensory experiences in food, beverages, and personal care products. The compound is classified as Generally Recognized as Safe (GRAS) by regulatory bodies, making it a popular choice for food applications. Its versatility extends to pharmaceutical and chemical industries, where it serves as an intermediate in synthesis processes.
Physical and Chemical Properties
Gamma-Octalactone is a colorless to pale yellow liquid with a characteristic sweet, coconut-like odor. It has a molecular weight of 142.20 g/mol and a density of 0.97 g/cm³. The compound is soluble in alcohol and oils but only slightly soluble in water, which influences its formulation in various applications. Its boiling point ranges between 234-235°C, and it remains stable under normal storage conditions. The lactone ring structure contributes to its stability and reactivity, making it suitable for controlled chemical modifications.
Main Applications
Gamma-Octalactone is primarily used as a flavoring agent in the food industry, imparting coconut and creamy notes to products like baked goods, candies, and dairy alternatives. In the fragrance industry, it is valued for its sweet, tropical aroma and is often included in perfumes, soaps, and lotions. Beyond sensory applications, it serves as a chemical intermediate in the synthesis of more complex compounds. Its role in pharmaceuticals includes use as a precursor in drug formulation, though this application is less common compared to its flavor and fragrance uses.
Safety and Storage
Gamma-Octalactone is generally safe for use in food and cosmetics, with no significant toxicity reported at standard usage levels. However, prolonged skin contact should be avoided to prevent potential irritation. Proper storage involves keeping the compound in a cool, dry place, away from direct light and oxidizing agents to maintain its stability. For industrial handling, standard laboratory precautions such as gloves and ventilation are recommended. Regulatory compliance, including GRAS status, ensures its safe integration into consumer products.
B2B Procurement Guide
When procuring Gamma-Octalactone, B2B buyers should prioritize suppliers with certifications for food-grade or pharmaceutical-grade products, depending on the intended use. Key considerations include verifying the CAS number (104-50-7) and requesting detailed purity specifications to ensure consistency in quality. Prices typically range between $50-$100 per kg, influenced by order volume and purity levels. Buyers are advised to establish long-term relationships with reputable suppliers to secure competitive pricing and reliable supply chains.
