How is the chemical identity of 12-Hydroxy Stearic Acid verified against standard Stearic Acid for grease production?

Verification is primarily conducted through the measurement of the hydroxyl value and melting point, as CAS 106-14-9 contains a hydroxyl group at the C12 position which is absent in standard stearic acid. This specific functional group is what allows for the complexation with metal hydroxides to form the high-dropping-point greases required in industrial machinery.

Is 12-Hydroxy Stearic Acid suitable for use as a primary thickener in high-temperature mineral oil formulations?

Yes, it is typically applied as the lead fatty acid component in the manufacture of high-performance lubricating greases. In these industrial processes, it reacts with lithium hydroxide or other bases to create a soap fiber network that maintains consistency and lubrication efficacy across a wide temperature range, commonly exceeding 120°C in continuous operation.

12-Hydroxy Stearic Acid CAS 106-14-9

12-Hydroxy Stearic Acid, identified by CAS 106-14-9, is a saturated fatty acid derived from hydrogenated castor oil that functions as a high-efficiency gelling agent and structural modifier within the Industrial & Specialty Chemicals sector. This hydroxylated fatty acid serves as a primary precursor for high-performance lithium-base lubricating greases, facilitating the formation of a stable fibrous matrix that enhances mechanical stability and water resistance in extreme-pressure environments. Beyond lubrication, it is widely utilized as a processing aid and internal lubricant in rigid plastics and rubber compounding to improve surface finish and flow characteristics without compromising thermal integrity. We provide this material with competitive factory pricing to support global manufacturing requirements, ensuring that all batches meet customized specifications for titer point and hydroxyl value. Our logistics infrastructure is optimized for bulk supply, and every shipment is accompanied by comprehensive technical documentation, including MSDS, TDS, COA, to ensure regulatory compliance and process safety.

Applications

Lubricating Greases: The primary raw material for Lithium and Calcium 12-hydroxystearate greases, providing excellent heat resistance and shear stability.
Plastics and Rubber: Functions as an internal lubricant and mold release agent for PVC, polystyrene, and ABS, reducing friction during extrusion.
Chemical Intermediates: Used in the synthesis of specialized esters and amides for the coatings and textile industries.
Personal Care (Industrial Processing): Acts as a consistency regulator in wax-based industrial formulations and professional-grade salves.

Storage & Safety

Storage: Store in a cool, dry, and well-ventilated area. Protect from direct sunlight and moisture to prevent clumping. Keep away from strong oxidizing agents.
Handling: Use standard industrial hygiene practices. Avoid dust formation and inhalation of fine particles.
PPE Recommendations: Wear safety glasses with side shields and protective gloves (nitrile or PVC). In areas with high dust concentration, a NIOSH-approved dust mask is recommended.

Quality Assurance

Our production facility utilizes advanced vacuum distillation and hydrogenation technology to ensure a high-purity product with consistent thermal properties. Each batch undergoes rigorous testing for hydroxyl value and iodine value to guarantee performance in grease thickening. We maintain strict batch-to-batch traceability, providing the technical reliability required for critical industrial lubrication and polymer processing applications.
