Product Highlights
  • Peroxy-Blend® PB33 oxidant is a formulated specialty oxidant containing hydrogen peroxide intended for use in a variety of water based cleaners. The product is efficient for formulation of alkaline cleaners. Cleaners made with Peroxy-Blend® PB33 oxidant will perform well on organic soils such as grease and oil, as well as protein soils.
  • When Peroxy-Blend® PB33 oxidant is used in acidic cleaning formulations (e.g. bathroom cleaners etc.) etching attack on metal fixtures is inhibited and short-term passivation of these surfaces is achieved. This results in reduced corrosion of fixtures that are left brighter longer.
  • Peroxy-Blend® PB33 oxidant is an efficient source of active oxygen for your bleaching formulations. Its primary attribute is enhanced chemical stability combined with a significant contribution to cleaning. This is a combination benefit not seen with competitive products.
  • The chemical stability of the product transfers to your cleaning formulations and results in long lasting bleaching performance over a wide pH range.
  • Peroxy-Blend® PB33 oxidant is an optimized specialty oxidant designed for use in all types of aqueous based cleaners for hard surfaces, e g. cleaning in place, machine cleaning, RTU cleaners, heavy-duty cleaners and cleaning concentrates. It can also be used in soft surface cleaning like laundry, pre-spotting upholstery and carpet. It is approved by the United States EPA for Safer Choice CleanGredients.
  • Peroxy-Blend® PB33 oxidant is intended for use with nonionic, cationic, anionic and amphoteric surfactants. This combination at neutral to alkaline pH provides excellent degreasing. The type of surfactant used will determine the foam characteristic of the cleaner.
