Description

1-o-Octadecanoyl-2N-Glycerol is a synthetic glycerolipid derivative, specifically a monoacylglycerol where the fatty acid chain is stearic acid. This compound is valued for its role as a versatile chemical intermediate and functional ingredient in advanced formulations. It is primarily utilized by industries focused on pharmaceutical research, cosmetic science, and the development of specialty surfactants and lipid-based delivery systems.

Application

• Pharmaceutical Excipient: Used in the formulation of lipid-based drug delivery systems (e.g., solid lipid nanoparticles, nanoemulsions) to enhance drug solubility and bioavailability.
• Cosmetic & Personal Care Ingredient: Serves as an emollient, emulsifier, and texture enhancer in creams, lotions, and makeup products.
• Biochemical Research: Acts as a substrate or intermediate in enzymatic studies and the synthesis of more complex phospholipids and glycolipids.
• Food-Grade Emulsifier (Potential): Can be investigated for use as a food additive (emulsifier) subject to regional regulatory approval and specific purity grades.
• Industrial Surfactant Precursor: A key building block for the synthesis of non-ionic surfactants and other amphiphilic compounds.
• Lipidomics & Analytical Standards: Employed as a reference standard in mass spectrometry and chromatography for lipid analysis and quantification.
