Description

1,3-Distearoyl-2-Elaidoyl Glycerol is a structured triglyceride (TAG) with a specific fatty acid configuration, where the sn-1 and sn-3 positions are esterified with stearic acid and the sn-2 position with elaidic acid. This precise molecular architecture is critical for applications requiring controlled melting behavior, crystallization kinetics, and specific physical properties in lipid matrices. It serves as a high-value functional ingredient and a key reference standard for analytical and research purposes. Target industries include specialty food science, pharmaceutical excipient development, and advanced materials research where the physical behavior of fats is paramount.

Application

• Reference Standard for Lipid Analysis: Used as a certified standard in chromatography (HPLC, GC) for the identification and quantification of trans-fatty acids and complex triglyceride mixtures in food and biological samples.
• Food Science & Fat Structuring: Acts as a structuring agent or model fat in the research and development of specialized confectionery fats, margarines, and low-trans or zero-trans fat products to study crystallization and texture.
• Pharmaceutical Excipient Research: Investigated as a component in lipid-based drug delivery systems (e.g., solid lipid nanoparticles, self-emulsifying drug delivery systems - SEDDS) to modulate drug release profiles and enhance bioavailability.
• Biochemical & Nutritional Studies: Employed in metabolic research to understand the absorption, metabolism, and health impacts of specific triglyceride structures, particularly those containing trans-fatty acids.
• Cosmetic & Personal Care Formulations: Used in the development of high-end emollients, stabilizers, and texture modifiers in creams and ointments due to its specific melting characteristics.
• Industrial Lubricant & Grease Additive: Serves as a bio-based additive or model compound in the formulation of specialized lubricants and greases, contributing to desired viscosity and thermal properties.
