Description

1,2-Dipalmitoyl-3-Lauroylglycerol is a structured triglyceride, a specific triacylglycerol molecule with defined fatty acid chains at the sn-1, sn-2, and sn-3 positions. This precise molecular architecture is critical for applications requiring controlled lipid digestion, absorption, and crystallization behavior. It is primarily utilized by researchers and manufacturers in the pharmaceutical, nutraceutical, and specialty chemical industries for developing advanced lipid-based delivery systems and functional ingredients.

Application

• Pharmaceutical Excipient: Used as a lipid matrix in the formulation of solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) for controlled drug delivery.
• Nutraceutical Carrier: Serves as a structured lipid base for enhancing the bioavailability of poorly soluble bioactive compounds, fat-soluble vitamins, and ω-3 fatty acids.
• Biochemical Research: Employed as a standard or substrate in lipid metabolism studies, enzymatic assays (e.g., lipase activity), and membrane biophysics research.
• Cosmetic Formulations: Acts as an emollient and texture-enhancing agent in high-end skincare products, providing specific melting properties and skin feel.
• Food Science Research: Investigated for its role in modifying the physical properties of fats, such as melting point and crystallization kinetics, in specialized food applications.
• Reference Standard: Used as a high-purity analytical standard in chromatography (HPLC, GC) for the identification and quantification of complex lipid mixtures.

Quality Control

Our 1,2-Dipalmitoyl-3-Lauroylglycerol is produced and tested under a strict quality management system. Each batch undergoes comprehensive analytical characterization to ensure identity, purity, and consistency. Specifications are designed to meet the rigorous demands of research and formulation. A Certificate of Analysis (COA) detailing purity, impurity profile, and relevant physical constants is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) to minimize oxidation. This material is hygroscopic (moisture-sensitive) and should be handled in a dry environment to prevent hydrolysis. For long-term storage, keep containers sealed and under refrigeration.
