Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: GLP-compliant, guideline study, available as an unpublished report, reliable without restrictions
Justification for type of information:
A discussion and report on the read across strategy is given as an attachment in IUCLID Section 13.
Reason / purpose:
read-across: supporting information
Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
GLP compliance:
yes (incl. certificate)
Type of method:
pour point
Key result
Melting / freezing pt.:
ca. 31 °C
Atm. press.:
ca. 101.3 kPa
Remarks on result:
other: Pressure not stated, therefore assumed the standard
Conclusions:
The pour point of the test item has been determined to be 31± 3°C (304±3 K).
Executive summary:

The determination of the Melting/Freezing Temperature was carried out using the pour point method, designed to be compatible with OECD guideline 102.

This is a GLP-compliant, guideline study, thus the result is reliable without restrictions.

Description of key information

There is no data available for Resin acids and rosin acids, reaction products with formaldehyde, sodium salts. However, data available from a structural analogue Resin acids and rosin acids, reaction products with formaldehyde, potassium salts is used as read across.

The melting points of substances in the category Rosin, hydrogenated rosin and their salts range from 31 to >300°C.

The pour point of Resin acids and rosin acids, reaction products with formaldehyde, potassium salts is 31 ± 3°C.


Key value for chemical safety assessment

Additional information

There is no data available for Resin acids and rosin acids, reaction products with formaldehyde, sodium salts. However, data available from a structural analogue Resin acids and rosin acids, reaction products with formaldehyde, potassium salts is used as read across.

A GLP-compliant study, conducted according to OECD Guideline 102, was provided for Resin acids and Rosin acids, reaction products with formaldehyde,
