Pionin

Pionin (CAS 15763-48-1), also known commercially as Quaternium-73, is a quaternary ammonium compound used as an antimicrobial active in pharmaceutical and personal care formulations.

It functions as a broad-spectrum biocide and preservative, targeting microbial contamination in finished products and manufacturing environments. In topical pharmaceutical preparations, it is incorporated to maintain sterility.

Personal care manufacturers use it in rinse-off and leave-on products, including shampoos, conditioners, and skin cleansers, where microbial control is a formulation requirement for safety.

It is also evaluated for use in antiseptic preparations where surface-active biocidal performance is needed alongside acceptable skin compatibility. This makes it versatile for various hygiene applications.

Industrial disinfectant formulators may consider it where quaternary ammonium activity is specified in the end-use product profile. It provides reliable performance across different industrial settings.

Pionin is typically supplied as a liquid solution or solid form depending on the grade and intended application. Technical and pharmaceutical grades are available to meet specific purity requirements.

Buyers sourcing for pharmaceutical or cosmetic applications should confirm grade specifications and documentation, including CoA and relevant compendial compliance, with the supplier prior to procurement.
