Overview
Hexyl hexanoate, also known as hexyl caproate, is an ester derived from hexanoic acid and hexanol. It is widely recognized for its fruity aroma, resembling apple or pineapple, making it a popular choice in the flavor and fragrance industries. The compound is synthesized through esterification, a process combining an alcohol and an acid. This ester is primarily utilized in food flavorings and cosmetic fragrances due to its pleasant scent and stability. Its synthetic nature allows for consistent quality and availability, which is crucial for industrial applications. The chemical is typically supplied as a liquid, ensuring ease of handling and incorporation into various formulations.
Physical and Chemical Properties
Hexyl hexanoate 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 ranging between 0.86 and 0.87 g/cm³. The boiling point is around 245-247°C, indicating its stability under moderate heat conditions. The ester is soluble in alcohol and oils but insoluble in water, which influences its application in hydrophobic formulations. Its stability under recommended storage conditions ensures a long shelf life, provided it is kept in a cool, dry place away from direct light. These properties make it suitable for use in both food and cosmetic products.
Main Applications
Hexyl hexanoate is predominantly used as a flavoring agent in the food industry, imparting fruity notes to candies, beverages, and baked goods. Its compatibility with other flavor compounds allows for versatile formulations. In the cosmetics industry, it serves as a fragrance component in perfumes, lotions, and soaps. The ester's stability and non-reactive nature make it ideal for long-lasting scent profiles. Additionally, it is sometimes employed in household products like air fresheners and cleaning agents to enhance their olfactory appeal. Its applications are broad, reflecting its utility in both consumer and industrial products.
Safety and Storage
While hexyl hexanoate is generally considered safe for use in regulated quantities, proper handling is essential to avoid potential hazards. Direct contact with skin or eyes should be avoided, and inhalation of vapors should be minimized by working in well-ventilated areas. Storage recommendations include keeping the compound in tightly sealed containers, away from heat sources and direct sunlight. These measures prevent degradation and maintain the ester's efficacy over time. Safety data sheets (SDS) should always be consulted for detailed handling and emergency procedures.
B2B Procurement Guide
When procuring hexyl hexanoate, industrial buyers should prioritize suppliers who provide detailed specifications, including CAS number (6378-65-0) and purity levels. Bulk purchasing can lead to cost savings, but quality should not be compromised for price. It is advisable to request samples for testing before large-scale orders to ensure the product meets application requirements. Reliable suppliers often offer technical support and documentation, such as certificates of analysis (CoA), which are critical for compliance and quality assurance. Long-term partnerships with reputable manufacturers can also ensure consistent supply and competitive pricing.
