Didecyldimonium carbonate

Didecyldimonium carbonate (CAS 148788-55-0) is a quaternary ammonium compound used as a biocide and antimicrobial active in industrial and institutional formulations.

Where is Didecyldimonium carbonate used?

• Hard surface disinfectants and institutional cleaners: broad-spectrum antimicrobial efficacy against bacteria and fungi at low use concentrations
• Water treatment: microbial growth control in cooling towers and process water systems
• Personal care and cosmetics: preservative active in rinse-off and leave-on products
• Sanitizing formulations: surfactant component that contributes to surface wetting and microbial kill

Good to know: Its carbonate salt form offers a milder pH profile than halide-based quats, a practical alternative where residue or corrosivity is a concern.

Commercial specifications

• Aqueous solution with varying active content concentrations
• Packaging: drums to IBC containers depending on order volume
