Description of key information

Calculation with US-EPA EPIWIN software: HENRYWIN Program v3.20:

Bond Est : 4.43E-013 atm-m3/mole (4.49E-008 Pa-m3/mole)

Group Est: 1.02E-017 atm-m3/mole (1.03E-012 Pa-m3/mole)

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
0.004
at the temperature of:
25 °C

Additional information

The prediction for the distribution between aqueous solution and air for the substance D-glucopyranoside methyl 2,6 -dioleate was determined by the computer program HENRYWIN v3.20 (EPIWIN software) by US-EPA (Chemservice S.A., 2017). The program calculates the Henry´s Law Constant based on the Bond Method as 4.49 E-008 Pa*m³/mol at a temperature of 25 °C. The Group Method estimation resulted in an Henry´s Law Constant of 1.03E-012 Pa*m³/mol).

No GLP criteria are applicable for the usage of this tool, but due to the fact that it is a scientifically accepted calculation method the estimations performed are reliable with restrictions and can be used for the chemical safety assessment.
