Warwick™B620 is a tetraacetylethylenediamine (TAED) agglomerate for bleach activation in powder based products. Warwick™B620 is designed for BPR or EPA registered users where biocidal claims are being made. Warwick™B620, along with an oxygen based donor, produces peracetic acid which is a broad spectrum biocide that kills bacteria, viruses and spores. By generating low levels of peracetic acid in situ, the oxidizing power and biocidal effect can be delivered safely, conveniently and economically. Warwick™620 provides a hygienic wash and reduces malodours produced by bacterial action.
