Sodium dodecylbenzenesulfonate

Density

Link to relevant study record(s)

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 g/cm³

Temp.:

20 °C

Remarks on result:

other: 20 deg C for 60% slurry

True specific gravity, can be expressed mathematically as:

SG_true = 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, sodium salt is 1 g/cm3 at20 deg C for 60% slurry according to the cited references( reliable data handbook data) .
