Description

Bis(1-Carboxyethyl Stearate)Magnesium is a magnesium salt of a stearic acid derivative, functioning as a versatile metal soap and additive. This compound is valued for its role as a stabilizer and lubricant, offering thermal stability and compatibility in polymer systems. It is primarily needed by manufacturers in the plastics, rubber, and specialty chemical industries for applications requiring metal-based additives.

Application

• As a heat stabilizer and lubricant in polyvinyl chloride (PVC) and other halogenated polymer processing.
• As a functional additive in rubber compounding to improve processing characteristics and product performance.
• As a metal soap catalyst or intermediate in the synthesis of specialty esters and lubricants.
• As a viscosity modifier and gelling agent in greases and industrial lubricant formulations.
• As a potential acid scavenger in polymer systems to neutralize acidic degradation products.
• In the production of cosmetic and personal care products as a thickener or emulsion stabilizer.

Quality Control

Our Bis(1-Carboxyethyl Stearate)Magnesium is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and heavy metals are 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 room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption and caking.
