Copper monoxide
Description
Copper monoxide (CAS 1317-38-0), also known as copper(II) oxide, is an inorganic compound used across industrial manufacturing as a pigment, biocidal agent, and chemical intermediate.
It delivers controlled copper ion release, which underpins its function in antimicrobial and surface-active applications. In personal care and cosmetics, it is incorporated into formulations where copper-based activity supports scalp and skin preservation.
Construction and coatings manufacturers use it as a pigment to achieve stable brown-black coloration in ceramic glazes, glass, and specialty coatings. Textile and leather processors apply it in dyeing auxiliaries and finishing treatments.
These treatments are essential where surface modification and biocidal protection are required. In printing and packaging, it contributes to specialty ink formulations and functional coatings where antimicrobial performance is a specification requirement.
Copper monoxide is supplied as a fine black powder in technical and industrial grades. Particle size distribution and purity levels vary by application, with high-purity grades available for electronic and specialty chemical uses.
Standard packaging includes multi-wall bags and bulk quantities suited to industrial procurement volumes. This ensures reliable supply chains for manufacturers requiring consistent chemical properties and high-volume availability for large-scale production.
