Description

Stearic Acid, Ester With Lactic Acid, Ca Salt is a calcium-based metallic soap derived from stearic and lactic acids. This compound is valued for its role as a versatile stabilizer and lubricant in polymer processing and other industrial formulations. It is primarily utilized by manufacturers in the plastics, rubber, and personal care industries seeking to enhance product performance and processing characteristics.

Application

• Acts as a heat stabilizer and lubricant in the processing of polyvinyl chloride (PVC) and other thermoplastic resins.
• Functions as an internal lubricant and flow promoter in engineering plastics and masterbatches to improve mold release and surface finish.
• Serves as a water-repellent agent and thickening stabilizer in cosmetic and personal care products, such as creams and ointments.
• Used as a processing aid and anti-caking agent in rubber compounding and various powder formulations.
• Employed as a corrosion inhibitor and additive in greases, lubricants, and metalworking fluids.
• Acts as a co-stabilizer in combination with primary stabilizers for enhanced thermal stability in polymer applications.

Quality Control

Our Stearic Acid, Ester With Lactic Acid, Ca Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for composition, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as calcium content, acid value, and moisture 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). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
