Description

1,2,3-Propanetriyl=1,3-Bishexadecanoate 2-Icosanoate is a high-purity synthetic triglyceride, specifically a mixed ester of glycerol with palmitic and arachidic acids. This compound matters for its role as a versatile, high-melting-point lipid component and chemical intermediate in advanced formulations. It is needed by manufacturers in the cosmetics, personal care, and specialty lubricants industries seeking consistent, high-quality raw materials for product development and process chemistry.

Application

• Cosmetic & Personal Care Formulations: Acts as an emollient, viscosity modifier, and structuring agent in creams, lotions, and solid stick products like lip balms and deodorants.
• Pharmaceutical Excipient: Used as a lipid matrix in controlled-release drug delivery systems and as a base for suppositories and ointments.
• Specialty Lubricants & Greases: Serves as a synthetic base oil or thickening agent in high-performance, biodegradable lubricant formulations.
• Food-Grade Additives (where specified): Can function as a release agent, texturizer, or carrier for flavors and colors in food processing, subject to appropriate purity grades.
• Chemical Synthesis Intermediate: Provides a defined triglyceride backbone for further chemical modifications, such as transesterification or hydrogenation, in fine chemical production.
• Candle & Wax Blending: Imparts desirable melting point and burn characteristics when blended with natural and synthetic waxes.

Quality Control

Our 1,2,3-Propanetriyl=1,3-Bishexadecanoate 2-Icosanoate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting key parameters are available upon request. We can support compliance requirements for various applications, including those referencing GMP or ISO 9001 standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 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. Keep away from strong oxidizing agents.
