Description

Calcium Isooctadecanoate is a metallic soap of isooctadecanoic acid, functioning as a versatile stabilizer and lubricant. Its primary commercial value lies in its ability to act as an effective heat stabilizer and acid scavenger in polymer formulations, preventing degradation during high-temperature processing. This compound is essential for manufacturers in the plastics, lubricant, and personal care industries seeking to enhance product stability and performance.

Application

• Polymer Stabilizer: Acts as a heat stabilizer and acid acceptor in PVC and other halogenated polymers to prevent dehydrochlorination and discoloration.
• Lubricant Additive: Used in greases and solid lubricants as a thickener and performance enhancer, providing water resistance and structural stability.
• Personal Care Products: Serves as a opacifying agent, viscosity modifier, and stabilizer in creams, lotions, and cosmetic formulations.
• Paint & Coating Additive: Functions as a flatting agent, dispersant, and stabilizer to improve the texture and durability of surface coatings.
• Plasticizer Co-stabilizer: Works synergistically with primary stabilizers like organotins or mixed metals to improve long-term thermal stability in flexible PVC applications.
• Waterproofing Agent: Imparts hydrophobic properties to textiles, paper, and construction materials.

Quality Control

Our Calcium Isooctadecanoate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, metal content, and physical properties. A Certificate of Analysis (COA) documenting key parameters is provided with each shipment to guarantee consistency and 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 sealed to prevent absorption of atmospheric moisture, which can affect product performance.
