Description of key information

The viscosity of DEGDB is estimated to be between 83 - 111 mPa.s though a definitive value is not available (Genovique Notebook 1-08, Page 29, 2010).

Key value for chemical safety assessment

Viscosity:
83 mPa · s (dynamic)
at the temperature of:
20 °C

Additional information

The viscosity determination presented within the report covered three products which contain:

  • Dipropylene glycol dibenzoate (DPGDB) alone (Benzoflex 9 -99),
  • A reaction mass of DPGDB and diethylene glycol dibenzoate (DEGDB) (Benzoflex 50),
  • A reaction mass of DPGDB, DEGDB and triethylene glycol dibenzoate (Benzoflex 2088).

The viscosities (mPa.s) determined were

DPGDB = 111

DPGDB + DEGDB = 91

DPGDB + DEGDB + TEGDB = 83

Based on the similarity of structures, it is reasonable to conclude that the viscosity of DEGDB alone will be within the range 83 - 111 mPa.s

If a precise value is required, a formal study on DEGDB will need to be conducted
