  • Chemical Properties
    • colourless liquid with an acrid odour

  • General Description
    • Colorless liquid with a strong, pungent acrid odor. Used as a bactericide and fungicide, especially in food processing; as a reagent in making caprolactam and glycerol; as an oxidant for preparing epoxy compounds; as a bleaching agent; a sterilizing agent; and as a polymerization catalyst for polyester resins.

  • Air & Water Reactions
    • Soluble in water

  • Reactivity Profile

    Self-reactive. Peracids should be handled only in small quantities and with extreme care when pure or very concentrated. Organic peracids, such as Peroxyacetic acid, are so unstable that they may explode during distillation, even under reduced pressure [NFPA 1991].

  • Usage
    • Environmentally friendly biocide; disinfectant in the food and beverage industry; bleaching agent for textiles and paper. Oxidizing agent in organic synthesis.

  • Health Hazard

    This is a very toxic compound. The probable human oral lethal dose is 50-500 mg/kg, or between 1 teaspoon and 1 ounce for a 150 pound person.

  • Fire Hazard

    Decomposes violently at 230F. When heated to decomposition, Peroxyacetic acid emits acrid smoke and fumes. Runoff to sewer may create a fire or explosion hazard. Powerful oxidizer. Isolate from other stored material, particularly accelerators, oxidizers, and organic or flammable materials. Avoid shock and heat. Hazardous polymerization may not occur.
