Description

Glycerol 1,3-Diheptanoate is a synthetic diester of glycerol and heptanoic acid, known for its role as a specialized lipid intermediate and emollient. This compound is valued for its ability to modify the physical properties of formulations, offering a unique balance of lipophilicity and stability. It is primarily utilized by manufacturers in the cosmetics, personal care, and pharmaceutical industries for product development and research applications.

Application

• Cosmetic & Personal Care Formulations: Serves as a high-purity emollient and skin-conditioning agent in creams, lotions, and serums.
• Pharmaceutical Excipient: Used as a lipid component in drug delivery systems, including lipid nanoparticles and topical preparations.
• Chemical Synthesis: Acts as a key building block or intermediate in the synthesis of more complex lipids, surfactants, and specialty esters.
• Lubricants & Release Agents: Employed in specialized industrial lubricant formulations and as a mold release agent due to its ester properties.
• Research & Development: Utilized in biochemical and material science research for studying lipid behavior and polymer plasticization.
• Food-Grade Applications (Potential): Can be explored for use as an emulsifier or texturizing agent in food products, subject to appropriate regulatory compliance and purity grades.

Quality Control

Our Glycerol 1,3-Diheptanoate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with key parameters such as assay, identity confirmation, and impurity profiles. Specifications can be aligned with cGMP guidelines for pharmaceutical applications or tailored to meet specific customer requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider maintaining under an inert atmosphere (e.g., nitrogen) to preserve stability and prevent degradation.
