Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusions:
The densities of aqueous solutions of sodium lactate were determined by the pycnometer method at 25 °C. The highly concentrated solutions with 60 %, 70 % and 77.15 % (w/w) Sodium lactate in water have the following relative densities:
60 % (w/w): 1.3131;
70 % (w/w): 1.3717;
77.15 % (w/w): 1.4085.
Executive summary:

The densities of aqueous solutions of Sodium lactate were determined by the pycnometer method at 25 °C. The highly concentrated solutions with 60 %, 70 % and 77.15 % (w/w) Sodium lactate in water have the following relative densities:
60 % (w/w): 1.3131;
70 % (w/w): 1.3717;
77.15 % (w/w): 1.4085.

This information is used in a read-across approach in the assessment of the target substance. For justification of read-across please refer to the read-across report atached to IUCLID section 13.

Description of key information

In an experimental study, which is comparable to OECD 109 (pycnometer method), the densities of aqueous solutions of Sodium lactate were determined by the pycnometer method at 25 °C. The highly concentrated solutions with 60 %, 70 % and 77.15 % (w/w) Sodium lactate in water have the following relative densities:

60 % (w/w): 1.3131;

70 % (w/w): 1.3717;

77.15 % (w/w): 1.4085.
