Description

1-Monolinolein is a high-purity monoglyceride derived from linoleic acid, a key ω-6 fatty acid. This compound serves as a versatile intermediate and functional ingredient, valued for its amphiphilic properties and specific biochemical activity. It is essential for manufacturers in the pharmaceutical, nutraceutical, and specialty chemical industries seeking reliable, high-quality lipid components for advanced formulations and research.

Application

• Pharmaceutical Excipient: Used as an emulsifier, solubilizer, and bioavailability enhancer in lipid-based drug delivery systems (e.g., self-emulsifying drug delivery systems - SEDDS).
• Nutraceutical & Dietary Supplements: Acts as a precursor or carrier for essential fatty acid supplements, supporting product stability and absorption.
• Biochemical Research: Serves as a critical substrate or standard in enzymatic studies, lipid metabolism research, and membrane biology.
• Cosmetic Formulations: Employed as a non-ionic surfactant and emollient in creams, lotions, and other personal care products for its skin-conditioning properties.
• Food Grade Emulsifier: Functions as a food additive (E471) in specific applications requiring a high-purity monoglyceride source.
• Chemical Synthesis: Utilized as a building block for the synthesis of more complex lipids, glycolipids, and specialty esters.

Quality Control

Our 1-Monolinolein is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide Certificates of Analysis (COA) detailing key parameters such as assay, fatty acid profile, and impurity limits. Specifications can be aligned with pharmaceutical (GMP) or food-grade (FCC) requirements upon request.

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. For long-term storage, keep the material frozen (-20°C). The container should be kept in a cool, dry, and well-ventilated area separate from strong oxidizing agents.
