Overview
Capric acid, or decanoic acid, is a medium-chain fatty acid naturally present in coconut oil, palm kernel oil, and dairy fats. It is a key intermediate in the synthesis of various esters and derivatives used across multiple industries. The compound is valued for its stability and versatility in industrial and food applications. Capric acid is synthesized through the hydrolysis of triglycerides found in natural oils. Its relatively simple structure and chemical properties make it a preferred choice for manufacturers in the food, cosmetic, and pharmaceutical sectors.
Physical and Chemical Properties
Capric acid is a white crystalline solid at room temperature but melts into a clear, oily liquid when heated above 31.6°C. It has a faint, characteristic odor and is hydrophobic, making it insoluble in water but soluble in organic solvents like ethanol and ether. The acid's boiling point is 269°C, and it has a density of 0.893 g/cm³. Its molecular weight is 172.26 g/mol. These properties make capric acid suitable for high-temperature applications and formulations requiring lipid solubility.
Main Applications
Capric acid is primarily used in the production of esters for perfumes and flavorings due to its mild odor and stability. It serves as a precursor for lubricants and plasticizers in industrial applications. In the food industry, capric acid is used as an additive and preservative. It also finds applications in pharmaceuticals, particularly in antimicrobial formulations and drug delivery systems. Its derivatives are employed in cosmetics for emulsifying and texturizing properties.
Safety and Storage
Capric acid is generally considered safe but can cause irritation upon contact with skin or eyes. Proper personal protective equipment (PPE), such as gloves and goggles, should be worn when handling the substance. Storage conditions should include a cool, dry environment away from strong oxidizers. Containers must be tightly sealed to prevent moisture absorption and contamination. Proper ventilation is recommended to avoid inhalation of vapors during handling.
B2B Procurement Guide
When procuring capric acid, buyers should verify the purity level, which typically ranges from 98% to 99.5%. Supplier certifications, such as ISO or GMP, are crucial for quality assurance. Bulk purchases often come in 25 kg drums or larger containers. Prices vary based on purity, quantity, and supplier location. It's advisable to request samples and conduct lab tests before large-scale procurement to ensure compliance with industry standards.
