Description

Ammonium benzoate (CAS 1863-63-4) is the ammonium salt of benzoic acid, supplied as white crystals under trade names including Vulnoc AB, Vulnoc ABS, and Vulnocab. It carries no assigned E-code and is catalogued under HS code 29163100. The molecular formula is C7H6O2.H3N.

In rubber and elastomer compounding, ammonium benzoate functions as a non-nitrosamine-forming vulcanisation accelerator and antioxidant, improving cure efficiency without generating carcinogenic byproducts. In aqueous coatings and adhesive formulations, it acts as a pH buffer and antimicrobial preservative, inhibiting microbial growth by disrupting cell membrane integrity at mildly acidic conditions.

Ammonium benzoate is available in technical and extra-pure grades, with the latter meeting FCC and Ph.Eur. specifications for pharmaceutical and food-contact applications. The substance is registered under REACH and supplied in fibre drums or multi-layer bags; minimum order quantities and packaging formats are confirmed at enquiry stage.
