Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Study period:
- 1989
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: EPA-TSCA guideline 796.1950
- GLP compliance:

- Type of method:
- gas saturation method
- Temp.:
- 60 °C
- Vapour pressure:
- 0 Pa
- Temp.:
- 25 °C
- Vapour pressure:
- < 0 Pa
- Transition / decomposition:
- no
- Conclusions:
- The vapor pressure of substance was determined at 60°C using the gas-saturation technique. The average vapor pressure at each temperature was determined by averaging the results of the three separate test systems using a low (≈ 5mL/min) flow rate. The vapor pressure of substance at 60°C was determined to be 2.11*10^-5 Pa. The vapor pressure at 25°C will be less than 1.33*10^-5 Pa.
Reference
The vapour pressure of piperonyl butoxide was determined by coating non-radiolabeled piperonyl butoxide onto purified white sand, volatilizing the test material from the sand at 60°C at 5mL/min, trapping the volatilized material using SPICE C18 resin traps and employing HPLC analysis to determine the amount of material volatilized.
Vapour pressure at 25°C is calculated to be less than 0.0000133 Pa.
Description of key information
The vapor pressure of PBO at 60°C was determined to be 2.11*10^-5 Pa (EPA-TSCA guideline 796.1950).
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 60 °C
Additional information
The vapor pressure of substance was determined at 60°C using the gas-saturation technique. The average vapor pressure at each temperature was determined by averaging the results of the three separate test systems using a low (≈ 5mL/min) flow rate. The vapor pressure of substance at 60°C was determined to be 2.11*10^-5 Pa.
The vapor pressure at 25°C will be less than 1.33*10^-5 Pa.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
