Type of information:

read-across from supporting substance (structural analogue or surrogate)

Adequacy of study:

key study

Justification for type of information:

For justification of read-across please refer to the attached read-across report (see IUCLID section 13).

Reason / purpose for cross-reference:

read-across source

Key result

Type:

relative density

Density:

1.16 other: dimensionless

Temp.:

25 °C

Remarks on result:

other: 70 % (w/w) solution of ammonium lactate in water.

Conclusions:

The relative density of a 70 % (w/w) solution of Ammonium lactate in water was determined by the pycnometer method at 25 °C. The solution has a relative density of 1.1596.

Executive summary:

The relative density of a 70 % (w/w) solution of Ammonium lactate in water was determined at 25 °C according to a method which is comparable to OECD 109 (pycnometer method). The relative density of the 70 % (w/w) solution of Ammonium lactate in water at 25 °C is 1.1596.
