Overview
Ethyl Decanoate, also known as Ethyl Caprate, is a fatty acid ester derived from decanoic acid and ethanol. It is widely recognized for its fruity, waxy odor, making it a popular choice in the flavor and fragrance industries. The compound is synthesized through esterification, a process that combines decanoic acid with ethanol in the presence of a catalyst. This ester is valued for its stability and compatibility with various formulations. It is commonly used in food flavorings, perfumes, and cosmetic products. Its ability to impart a pleasant aroma and its relatively low toxicity make it a versatile ingredient in multiple applications.
Physical and Chemical Properties
Ethyl Decanoate is a colorless to pale yellow liquid with a characteristic fruity odor. It has a molecular weight of 200.32 g/mol and a density of 0.862 g/cm³. The compound is soluble in organic solvents like alcohol and ether but is insoluble in water. Its boiling point ranges between 243-245°C, and it has a melting point of -20°C. These properties make it stable under normal storage and handling conditions. The ester is also resistant to hydrolysis under neutral or slightly acidic conditions, contributing to its longevity in formulated products.
Main Applications
Ethyl Decanoate is primarily used as a flavoring agent in the food industry, where it imparts a fruity, grape-like taste to products such as candies, beverages, and baked goods. In the fragrance industry, it serves as a middle note in perfumes and colognes, adding a waxy, floral undertone. Beyond flavors and fragrances, this ester is utilized as a solvent in the production of varnishes and lacquers. Its low volatility and pleasant odor make it suitable for use in cosmetics, including lotions and creams. Additionally, it is sometimes employed in pharmaceutical formulations as an excipient.
Safety and Storage
While Ethyl Decanoate is generally considered safe for use in regulated applications, proper handling is essential to minimize risks. It is advisable to avoid inhalation, ingestion, and prolonged skin contact. Personal protective equipment (PPE), such as gloves and goggles, should be used when handling the compound. Storage conditions should include a cool, dry, and well-ventilated area away from heat sources and open flames. The ester should be kept in tightly sealed containers to prevent contamination and degradation. In case of spills, absorbent materials like sand or vermiculite can be used for cleanup.
B2B Procurement Guide
When procuring Ethyl Decanoate, B2B buyers should prioritize suppliers with certifications such as ISO or GMP to ensure product quality and consistency. Key factors to consider include purity levels, typically ranging from 98% to 99.5%, and batch-to-batch uniformity. Price negotiations should account for order volume, with bulk purchases often attracting discounts. Buyers should also verify the supplier's ability to provide technical support and documentation, including Material Safety Data Sheets (MSDS). Logistics considerations, such as shipping conditions and lead times, are equally important to ensure timely delivery.
