Didecyldimonium carbonate

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

Its carbonate salt form offers formulators a milder pH profile compared to halide-based quats, making it a practical alternative where residue or corrosivity is a concern.

In hard surface disinfectants and institutional cleaners, it delivers broad-spectrum antimicrobial efficacy against bacteria and fungi at low use concentrations.

Water treatment programs incorporate it to control microbial growth in cooling towers and process water systems. Personal care and cosmetic formulators use it as a preservative active.

It is utilized in rinse-off and leave-on products where quat-based preservation is preferred. It also functions as a surfactant component in sanitizing formulations.

This chemical contributes to both surface wetting and microbial kill. Didecyldimonium carbonate is typically supplied as an aqueous solution with varying active content concentrations.

Technical grade is the standard commercial offering, though material meeting cosmetic-grade specifications is available for personal care applications.

Packaging ranges from drums to IBC containers depending on order volume. This versatile antimicrobial agent provides reliable performance across diverse industrial sectors.
