³Range defined as literature value ± 20 percent

Conclusions:

The vapor pressure of PFBSK+ was < 1.22E-05 Pa at 20°C ± 1°C determined by the spinning rotor gauge method (OECD Guideline 104 Vapor Pressure Curve and EPA OPPTS 830.7950 Vapor Pressure).

Executive summary:

The vapor pressure of PFBSK+ was examined in a spinning rotor gauge test conducted according to OECD Guideline 104 (Vapor Pressure Curve) and EPA OPPTS 830.7950 (Vapor Pressure). At 20°C ± 1°C the vapor pressure was <1.22E-05 Pascals.

The test was conducted according to internationally accepted test guidelines and was GLP compliant. It is reliable without restriction and suitable for Risk Assessment, Classification and Labeling.

At temperatures up to 105°C the vapor pressure is lower than the minimum dection limit of the apparatus (1.0E-05 hPa).

Conclusions:

The vapor pressure of PFBSK+ was < 1.0E-05 hPa at 20°C, 25°C and 50°C (Vapor Pressure Balance; EC-Guideline 92/69/EWGA4).

Executive summary:

The vapor pressure of PFBSK+ was examined in a vapor pressure balance test conducted according to EC-Guideline 92/69/EWGA4. The report noted that at temperatures up to 105°C, the vapor pressure was < 1.0E-05 hPa, the minimum detection limit of the measuring apparatus. Reported results were at 20°C, 25°C and 50°C the vapor pressure was < 1.0E-05 hPa.

The test was conducted according to internationally accepted test guidelines and was GLP compliant. It is reliable without restriction and suitable for Risk Assessment, Classification and Labeling.

Description of key information

The vapor pressure of PFBSK+ was determined to be < 1.22E-05 Pa at 20°C ± 1°C, according to OECD Guideline 104.

Additional information

The vapor pressure of PFBSK+ was determined to be < 1.22E-05 Pa at 20°C ± 1°C in the key study. The test was conducted according to OECD Guideline 104 and EPA OPPTS 830.7950, using the spinning rotor gauge test, therefore it is considered reliable without restriction. A supporting study conducted according to EC-Guideline 92/69/EWGA4 reported results of < 1.0E-05 hPa at 20°C, 25°C and 50°C and noted that at temperatures up to 105°C, the vapor pressure was < 1.0E-05 hPa, the minimum detection limit of the measuring apparatus. This study was conducted according to internationally accepted test guidelines and is considered reliable without restriction.
