Description

Triolein is a naturally occurring triglyceride composed of three oleic acid units, serving as a key reference standard and biochemical intermediate. Its high purity and defined structure make it essential for research, quality control, and the synthesis of more complex lipids. This compound is particularly valuable for laboratories and manufacturers in the pharmaceutical, cosmetic, and nutritional sectors requiring a reliable source of a pure, unsaturated triglyceride for analytical and formulation purposes.

Application

• Biochemical Research & Standard: Used as a primary standard in chromatography (HPLC, GC) for the quantification and identification of other triglycerides and lipids in complex matrices.
• Pharmaceutical Excipient & Carrier: Functions as a lipid-based carrier in drug delivery systems, such as lipid nanoparticles (LNPs) and self-emulsifying drug delivery systems (SEDDS), to enhance the bioavailability of poorly soluble active pharmaceutical ingredients (APIs).
• Cosmetic & Personal Care Formulations: Acts as an emollient and skin-conditioning agent in creams, lotions, and ointments, providing moisturizing properties and improving product texture.
• Nutritional Science & Food Analysis: Employed as a model compound in studies of fat metabolism, lipid oxidation, and as a calibration standard for analyzing edible oils and fats.
• Industrial Lubricant & Plasticizer Precursor: Serves as a raw material or intermediate in the production of bio-based lubricants, surfactants, and plasticizers due to its oleochemical origin.

Quality Control

Our Triolein is produced under a strict quality management system. Each batch is analyzed to ensure high chemical purity and identity, with testing typically including identification (IR, NMR), assay (HPLC), and checks for related substances. A comprehensive Certificate of Analysis (COA) detailing all test results and specifications is provided with every shipment. We can support compliance requirements for various applications, including research and cGMP manufacturing.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) at 2-8°C to minimize oxidation and prolong shelf life. Keep the container in a cool, dry, and well-ventilated area away from heat sources and incompatible materials.
