Peroxyacetic Acid, 3.5% (w/w)

• A ready-to-use peracetic acid solution: Peroxyacetic Acid, 3.5% (w/w) is a prepared solution. Peroxyacetic acid, also called peracetic acid, is a powerful oxidizer valued as a broad-spectrum disinfecting and sanitizing agent and as an oxidizing reagent in laboratory and industrial chemistry. Because it breaks down into relatively benign byproducts, it is widely used where effective microbial control is needed without leaving persistent chemical residues, making it popular across sanitation, water treatment, and food and beverage processing.
• Consistent, defined concentration: Supplied at a defined 3.5% (w/w) concentration, this solution delivers a known, ready-to-use strength that removes the need to prepare dilutions from a more concentrated and hazardous stock.
• Handling a reactive oxidizer: Peroxyacetic acid is a corrosive oxidizer and must be treated with care. It should be handled with appropriate personal protective equipment, kept well away from incompatible and combustible materials, and stored according to the manufacturer's guidance. As with any oxidizing acid, the Safety Data Sheet should be reviewed before use so that handling, spill response, and storage are understood in advance. The product carries a California Prop 65 warning.
• Choosing the right quantity: The solution is offered in two container sizes so the quantity can be matched to actual usage. Because peracetic acid is a reactive material with a finite useful life, buying an amount that will be used within a reasonable period is good practice, limiting how much oxidizer is stored on site and reducing waste. Selecting the appropriate size helps balance convenience against the responsible handling and storage that an oxidizing chemical requires.
