experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
This study is classified as reliable with restriction by CONCAWE. 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. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data

Applicant's summary and conclusion

Conclusions:
Slack Waxes are semi-solid hydrocarbons at ambient temperatures. This is done by visual inspection. A specific test method is not available but dataon pour point/melting point support the statement on physical state of the substance at ambient temperature.
Executive summary:

Slack Waxes are semi-solid hydrocarbons at ambient temperature and pressure. This is done by visual inspection. A specific test method is not available but data on pour point / melting point support the statement on physical state of the substance at ambient temperature. This study received a Klimisch score of 2 and is classified as reliable with restriction.
