Reference
Endpoint:
relative density
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
Justification for type of information:
According to the REACH regulation (“ECHA, guidance on information requirements and chemical safety assessment – chapter R.7a”), it is allowed to use handbook data as a reliable data source.
Qualifier:
no guideline followed
Principles of method if other than guideline:
Not applicable: handbook data
GLP compliance:
not specified
Type of method:
other: no data
Type:
relative density
Density:
1.04 g/cm³
Temp.:
25 °C
Remarks on result:
other: (liquid solution) at 25 deg C

True specific gravity, can be expressed mathematically as:

SGtrue = p sample/ p H2O

where p sample is the density of the sample and p H2O is the density of water.

 Specific gravity, as it is the ratio of densities, is a dimensionless quantity.

Specific gravity varies with temperature; reference and sample must be compared at the same temperature, or corrected to a standard reference temperature. Substances with a specific gravity of 1 are neutrally buoyant in water, those with SG greater than one are denser than water

Conclusions:
The relative density of Dodecylbenzenesulfonic acid, calcium salt is 1.04 g/cm3 at25 deg C for liquid solution according to the cited references( reliable data handbook data) .
