Description of key information

<10 mg/L at 20 °C, pH=6.95 (EU A.6, shake flask)
<1 mg/L (trend analysis)

Key value for chemical safety assessment

Additional information

The water solubility of the substance Propyleneglycol dioleate (CAS 105 -62 -4) was determined according EU method A.6 by using shake flask method.

Due to limitations of the analytical methods the limit value of <10 mg/L was determined.

Therefore another water solubility test with a similar substance (Decanoic acid, mixed diesters with octanoic acid and propylene glycol, CAS 68583 -51 -7) is used to assess water solubility of the test substance.

Water solubility is a property which depends - in a group of structural very similar substances - mainly on overall chain length. The read-across substance CAS 68583 -51 -7 has a shorter chain length then Propylenegycol dioleate and could therefore be seen as a "worst case". Therefore the solubility of Propyleneglycol dioleate (CAS 105 -62 -4) is given as <1 mg/L (trend analysis).
