Didecyldimonium bicarbonate

Didecyldimonium bicarbonate (CAS 148812-65-1) is a quaternary ammonium compound used as a biocidal active and surfactant across cleaning, water treatment, and personal care applications.

It delivers broad-spectrum antimicrobial performance while offering a more environmentally favorable counterion profile compared to conventional quat chloride salts in industrial formulations.

In home care and industrial cleaning formulations, it functions as a disinfecting surfactant in hard surface cleaners, sanitizers, and institutional hygiene products where microbial control is required.

Water treatment programs use it to control biofilm formation and microbial growth in recirculating and process water systems. It is also incorporated into personal care preservation systems.

In personal care, it is used in rinse-off formulations where surface-active biocidal action is needed. It also supports surface modification applications where controlled wetting is a requirement.

Didecyldimonium bicarbonate is typically supplied as an aqueous solution, with active content concentration varying by supplier and end-use specification for various manufacturing processes.

It is available in technical grade for industrial and institutional cleaning applications. Packaging ranges from drums to IBC containers, suited to industrial procurement volumes and logistics.
