Conclusions:
The relative density d20.5/4 of l-limonene is 0.8407 at 20.5 °C.
Executive summary:

The relative density of l-limonene was reported in The Merck Index 2006 as 0.8407 at 20.5 °C against water at 4 °C.

The reliability of this result has been considered as 2 (reliable with restrictions) because ‘The Merck Index’ is cited as a reference book containing peer reviewed data in the REACH Guidance Document R.7a.

Description of key information

Weight of evidence: Relative density of l-limonene at 20 °C : 0.84

Key value for chemical safety assessment

Relative density at 20C:
0.84

Additional information

In a weight of evidence approach relative density of l-limonene is estimated to be 0.84 consistent with all values reported for the two enantiomers (d- and l-limonene) being in the same order of magnitude.
