Neodecanoic Acid CAS 26896-20-8
Neodecanoic Acid (CAS 26896-20-8) is a highly branched C10 carboxylic acid, a clear liquid that stays fluid at low temperature and does not mix with water. The crowded acid group gives derivatives heat and hydrolysis resistance. It becomes soaps for paint driers, salts for PVC stabilizers and peroxide initiators for polymers. Esters serve synthetic lubricants, and the acid supports corrosion inhibitors and metal extraction. UATChem supplies technical grades in plastic drums and IBCs, with COA, TDS and SDS on request.

What Neodecanoic Acid Is
Neodecanoic Acid is a mixture of highly branched C10 saturated monocarboxylic acid isomers, formula C10H20O2. A crowded carbon next to the acid group creates steric hindrance, so the clear liquid resists oxidation and keeps derivatives stable under heat. It is insoluble in water. The acid becomes metal salts, peroxides and esters, linking coatings, polymers and lubricants. UATChem supplies the liquid, with acid value on the COA and TDS.
Driers, Stabilizers, Peroxides and Lubricant Uses
- Paint drier metal soaps. Metal salts of the acid act as driers in alkyd and industrial coatings.
- PVC stabilizers. The salts support heat stabilizer systems for PVC processing.
- Peroxide initiators. Peroxyneodecanoate derivatives serve free radical polymerization initiators.
- Lubricant esters and corrosion. The esters serve synthetic lubricants, and the acid supports corrosion inhibitors and metal extraction.
