Description

Octadecanoic Acid,18-A€Hydroxy- is a hydroxylated derivative of stearic acid, a key intermediate in the synthesis of specialized esters and polymers. This compound matters for its bifunctional nature, offering both a long alkyl chain and a reactive hydroxyl group, enabling precise chemical modifications. It is needed by manufacturers in the cosmetics, lubricants, and specialty chemical industries for producing emulsifiers, viscosity modifiers, and performance additives.

Application

As a key intermediate in the synthesis of waxes and esters for cosmetic and personal care formulations.
In the production of lubricant additives and metalworking fluids to enhance performance characteristics.
As a building block for polymer modification, particularly in creating specialized polyols for coatings and adhesives.
For use in textile auxiliaries as a softening or finishing agent.
In the manufacture of plasticizers and stabilizers for various polymer systems.
As a raw material for surfactants and emulsifiers in industrial and institutional cleaning products.
