Description

1,3-Distearin is a high-purity diglyceride, specifically the 1,3-isomer of glycerol distearate. This compound serves as a versatile intermediate and functional additive, valued for its emulsifying, stabilizing, and texturizing properties. It is essential for manufacturers in the food, cosmetic, and pharmaceutical industries seeking to improve product consistency and shelf life. Our supply ensures consistent quality and reliable availability for global industrial applications.

Application

• Food Industry: Used as an emulsifier and stabilizer in baked goods, margarines, and whipped toppings to improve texture and prevent separation.
• Cosmetics & Personal Care: Acts as a skin-conditioning agent, opacifier, and viscosity modifier in creams, lotions, and makeup formulations.
• Pharmaceuticals: Employed as an excipient in tablet and capsule formulations, aiding in controlled release and acting as a lubricant.
• Chemical Synthesis: Serves as a key intermediate for the production of more complex lipids, surfactants, and specialty esters.
• Industrial Applications: Functions as a processing aid, release agent, or anti-static agent in various manufacturing processes.

Quality Control

Our 1,3-Distearin is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets the required specifications for identity, purity, and composition. Certificates of Analysis (COA) documenting these results are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture. For long-term storage, consider using an inert atmosphere to minimize oxidation.
