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.

Where is Pionin used?

• Topical pharmaceuticals: incorporated to maintain sterility
• Personal care: rinse-off and leave-on products such as shampoos, conditioners and skin cleansers
• Antiseptics: evaluated where surface-active biocidal performance is needed alongside skin compatibility
• Industrial disinfectants: considered where quaternary ammonium activity is specified
• It functions as a broad-spectrum biocide and preservative targeting microbial contamination.

Good to know: 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.
