Reference

Endpoint:

water solubility

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2005

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: GLP status not known, guideline not known, information from a published handbook, acceptable with restrictions

Qualifier:

no guideline available

Guideline:

other: Data taken from secondary source. Guideline not stated.

Principles of method if other than guideline:

The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The International Chemical Safety Cards (ICSC) are produced by the WHOs International Programme on Chemical Safety (IPCS). The introduction to the ICSC states that they report “information collected, verified and peer reviewed by internationally recognized scientists”. Therefore, the values presented are acceptable as they are from a reliable secondary source of phys chem. data.

GLP compliance:

Remarks:

No data reported

Specific details on test material used for the study:

N/A

Key result

Water solubility:

20 mg/L

Temp.:

25 °C

pH:

7

Details on results:

Solubility in water is 0.002 g/100ml at 25°C. pH is assumed

N/A

Conclusions:

Interpretation of results: slightly soluble (0.1-100 mg/L)
The water solubility of the test substance is 20 mg/L, which is classifed as slightly soluble.

Executive summary:

The water solubility of the test substance is 20 mg/L, which is classified as slightly soluble. No information on the primary source of this data or the methods used is available. However, this information is taken from a reliable peer reviewed database and so can be considered reliable and suitable for use as the key study for this endpoint.

Description of key information

 The water solubility of the test substance is 20 mg/L, which is classified as slightly soluble.

Key value for chemical safety assessment

Water solubility:

20 mg/L

at the temperature of:

25 °C

Additional information

The water solubility of the test substance is 0.02 g/L, which is classified as slightly soluble. No information on the primary source of the data or the methods used is available. However, this information is taken from a reliable peer reviewed database and so can be considered reliable and suitable for use as the key study for this endpoint (WHO ICSC 2005). This value is also cited in a MITI study (1997) which was unavailable for review but was identified in the OECD SIDS. The QSAR model (US EPA 2009) predicts a water solubility of 110.6 mg/L at 25°C based on an experimental log Kow of 2.78, and a water solubility of 51.88 mg/L at 25°C based on an estimated log Kow of 3.16. This model and value are considered adequate to use for assessment as a supporting study.

The data presented here are for the high purity form of DCPD. No information is available specifically on the water solubility of the commercial form of DCPD but it is not expected to be significantly different from the high purity form.
