Copper oleate

CAS: 1120-44-1

Overview

Copper oleate (CAS 1120-44-1 ), also known as cupric oleate, is a copper-based organometallic compound used industrially as a biocide, corrosion inhibitor, and lubricant additive.

Its oil-soluble nature makes it effective in formulations where inorganic copper salts cannot be dispersed. In textile, leather, and paper processing, it functions as a preservative and antimicrobial agent.

This compound protects materials against fungal and microbial degradation during storage and use. Lubricant formulators incorporate it into metalworking fluids and greases where anti-wear properties are required.

In marine and industrial coatings, it acts as an antifouling and preservative component. It is particularly effective in treatments for canvas, cordage, and various industrial fabrics.

Corrosion-inhibiting formulations for metal surfaces also utilize this chemical where a film-forming, oil-soluble copper source is preferred over aqueous alternatives for long-term protection.

The product is typically supplied as a viscous liquid or semi-solid paste, depending on purity and formulation. It is available in technical grade, with concentration and copper content specified.

Bulk supply is standard for industrial buyers, with packaging in drums or intermediate bulk containers. Our logistics team ensures safe handling and timely delivery for all industrial orders.
