Water solubility
Administrative data
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: The water solubility given in the handbook is considered as reliable with restrictions as it was rated as a critical study in the available SIDS dossier ofr sodium percarbonate (OECD 2006).

Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): decomposes
The solubility of sodium percarbonate in water is high, but the substance rapidly dissociates in water. - Executive summary:
Handbook data on the water solubility of sodium percarbonate is available and is regarded as reliable and critical information (OECD 2006). The water solubility of the substance at 20 °C and pH 10.4 to 10.6 is approximately 140 g/L. However, sodium percarbonate rapidly dissociates in water and forms hydrogen peroxide and sodium carbonate.
