Overview
Tricaprylin is a medium-chain triglyceride (MCT) derived from caprylic acid, a saturated fatty acid. It is commonly used in industries such as food, pharmaceuticals, and cosmetics due to its unique properties. As a lipid, it serves as a carrier for fat-soluble compounds and provides a source of rapid energy. Its molecular structure consists of three caprylic acid chains esterified to a glycerol backbone. This configuration enhances its solubility in organic solvents and improves its bioavailability, making it a preferred choice for formulations requiring efficient nutrient delivery.
Physical and Chemical Properties
Tricaprylin is a colorless to pale yellow oily liquid with a density of approximately 0.95 g/cm³. It has a melting point of 10°C (50°F) and is insoluble in water but readily dissolves in organic solvents like ethanol and acetone. One of its key advantages is its high oxidative stability, which makes it resistant to rancidity. Additionally, its low viscosity and rapid absorption rate are beneficial for applications requiring quick metabolic utilization, such as sports nutrition and medical foods.
Main Applications
In the food industry, tricaprylin is used as a stabilizer, emulsifier, and energy source in products like infant formula, sports drinks, and dietary supplements. Its rapid digestion and metabolism make it ideal for ketogenic diets and clinical nutrition. The pharmaceutical industry utilizes tricaprylin as an excipient in drug formulations, particularly for enhancing the solubility of poorly water-soluble drugs. In cosmetics, it acts as an emollient and skin-conditioning agent, providing a non-greasy feel and improving product spreadability.
Safety and Storage
Tricaprylin is generally recognized as safe (GRAS) by regulatory authorities when used in accordance with good manufacturing practices. However, prolonged skin contact should be avoided to prevent potential irritation. For storage, it is recommended to keep the compound in a cool, dry place away from direct sunlight and heat sources. Properly sealed containers should be used to minimize exposure to air and moisture, which could degrade the product over time.
B2B Procurement Guide
When procuring tricaprylin, B2B buyers should prioritize suppliers who provide detailed specifications, including CAS number (538-23-8) and purity levels. Certificates of analysis (CoA) are essential to verify the product's quality and compliance with industry standards. Buyers should also consider the intended application when selecting a grade, as food-grade and pharmaceutical-grade tricaprylin may have different purity requirements. Bulk purchasing can reduce costs, but storage capacity and shelf life should be evaluated to prevent waste.
