Storage stability and reactivity towards container material
Administrative data
Link to relevant study record(s)
- Endpoint:
- storage stability and reactivity towards container material
- Type of information:
- other: Company data
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Perr reviewed data
- GLP compliance:
- no
- Conclusions:
- For save storage suitable container material and storage conditions apply.
- Executive summary:
Generally, peracetic acid is stable in containers made from glass ceramics, certain high density linear polyethylene grades, polyvinylchloride, poly-tetra-fluoroethylene and properly passivated stainless steel 304L and 316. However, it is important to check the compatibility and stability with all containers before long-term use; PAA can degrade (embrittle) plastics with extended contact time. Degradation rates are enhanced by elevated temperature. The German authorities have restricted the maximum storage time for solutions above 17% peracetic acid in standard polyethylene containers to six months from the day of filling. Extensions can be obtained for containers that exhibit long-term storage stability with PAA by passing the required test (drop test) after extended contact with peracetic acid. Peracetic acid solutions are capable of leaching metal ions from stainless steel. This effect is enhanced by mineral acids such as sulphuric acid, which may be added as catalyst. Many of these metal ions, e.g. iron, nickel, chromium and molybdenum can cause product instability.
Unsuitable container materials are: aluminium, carbon steel, some cross-linked polyethylene, metal alloys containing copper, tin, zinc, bronze and brass.
