- Executive summary:
The vapour pressure for both constituents of Rhamnolipid (CAS 147858-26-2) was predicted by MPBPWIN v1.43, which is implemented in EPIWIN v4.1 (US EPA 2012). The 'Modified Grain Method' was applied. The vapour pressure for CAS 37134-61-5 and CAS 4348-76-9 predicted by MPBPWIN v1.43 are 3.31E-16 Pa and 4.7E-23 Pa, respectively.

Description of key information
Estimations from a valid (Q)SAR model are used to address the endpoint, which is considered entirely appropriate for showing the expected very low vapour pressures of the constituents of the registration substance 'Decanoic acid, 3-[[6-deoxy-2-O-(6-deoxy-α-L-mannopyranosyl)-α-L-mannopyranosil-1-(carboxymethyl)octyl ester, mixture with 1-(carboxymethyl)octyl 3-[(6-deoxy-α-L-mannopyranosyl)oxy]-decanoate':
- Vapour pressure of 1st main constituent 'Decanoic acid, 3-[(6-deoxy-α-L-mannopyranosyl)oxy]-,1-(carboxymethyl)octyl ester' (CAS 37134-61-5): 3.31E-16 Pa at 25°C (estimated using MPBPWIN programme v1.43 by U.S. EPA);
- Vapour pressure of 2nd main constituent 'Decanoic acid, 3-[[6-deoxy-2-O-(6-deoxy-α-L-mannopyranosyl)-α-L-mannopyranosyl]oxy]-, 1-(carboxymethyl)octyl ester' (CAS 4348-76-9): 4.7E-23 Pa at 25°C (estimated using MPBPWIN programme v1.43 by U.S. EPA);
- Key value for MuC 'Decanoic acid, 3-[[6-deoxy-2-O-(6-deoxy-α-L-mannopyranosyl)-α-L-mannopyranosil-1-(carboxymethyl)octyl ester, mixture with 1-(carboxymethyl)octyl 3-[(6-deoxy-α-L-mannopyranosyl)oxy]-decanoate' (CAS 147858-26-2): 3.31E-16 Pa at 25°C, the higher vapour pressure of the two constituents.
Key value for chemical safety assessment
- Vapour pressure:
- 0 Pa
- at the temperature of:
- 25 °C
