Target Applications
Planned industrial and synthesis uses for 12-Hydroxystearic Acid (12-HSA) currently under commercial development.
Lithium Complex Greases
Reacts with lithium hydroxide to form lithium 12-hydroxystearate, the world's most widely used lubricating grease thickener soap.
Learn more →Coating Rheology Modifiers
Dispersed into solvent-borne industrial coatings and sealants to impart thixotropic viscosity, anti-sagging, and pigment suspension.
Learn more →Plastic & Rubber Processing
Functions as an internal lubricant and mold release agent for acrylic, PVC, and engineering thermoplastic compounding.
Learn more →Cosmetic Emollient Esters
Esterified into high-molecular-weight esters (e.g. trioctyldodecyl citrate derivatives) for long-wear color cosmetic sticks.

Packaging will be confirmed when commercial supply starts.
Frequently Asked Questions
How does 12-HSA soap fiber matrix stabilize lithium complex greases?
Reacting with lithium hydroxide yields lithium 12-hydroxystearate, which forms an interwoven fibrous network trapping base oil and raising drop point above 190°C.
What acid value and ester values govern 12-HSA flakes?
Acid value of 175 to 182 mg KOH/g, ester value of 180 to 190, melting point 74°C to 77°C, and iodine value under 3.5.
What role does 12-hydroxystearic acid play in acrylic coating finishes?
Reacted into acrylic polyols to enhance sag resistance, control pseudoplastic viscosity, and align metallic flake pigments evenly.
