Description

Calcium(2+) 12-Hydroxyoctadecanoate is the calcium salt of 12-hydroxyoctadecanoic acid, a key metallic soap widely used as a versatile rheology modifier and stabilizer. This compound is valued for its ability to impart thixotropic properties and improve the structural stability of various formulations. It is an essential ingredient for manufacturers in the coatings, lubricants, plastics, and personal care industries seeking to control viscosity and prevent sagging or settling.

Application

• Coatings & Paints: Acts as a primary thickener and anti-settling agent in solvent-based paints, varnishes, and industrial coatings to prevent pigment sedimentation and improve application properties.
• Lubricating Greases: Functions as a complexing agent and thickener in calcium complex greases, enhancing thermal stability, water resistance, and mechanical durability.
• Polymer & Plastic Additives: Serves as an internal lubricant and acid scavenger (stabilizer) in PVC and other polymer processing to improve flow and prevent degradation.
• Cosmetics & Personal Care: Utilized as a viscosity modifier and opacifying agent in creams, lotions, and stick formulations such as deodorants and lipsticks.
• Adhesives & Sealants: Employed to control rheology, prevent sagging in vertical applications, and stabilize filled systems.
• Printing Inks: Used to adjust the rheological profile, ensuring proper transfer and sharp print definition while preventing settling of pigments.

Quality Control

Our production of Calcium 12-Hydroxystearate adheres to stringent quality management protocols. Each batch is tested against key parameters including assay, acid value, moisture content, and particle size distribution to ensure consistent performance and purity. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

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.
