Reference
Endpoint:
density
Remarks:
density
Type of information:
migrated information: read-across based on grouping of substances (category approach)
Adequacy of study:
key study
Study period:
1999
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Determination of density by a scientifically accepted method. Read across concerns a product containing a substance.
Justification for type of information:
REPORTING FORMAT FOR THE ANALOGUE APPROACH
1. HYPOTHESIS FOR THE ANALOGUE APPROACH
Propanoic acid, 2-hydroxy-, C12-15-alkyl esters / 93925-36-1 / 300-338-1 contains the C12 and C14 alkyl lactates also present in Propanoic acid, 2-hydroxy, C12-C16 (even numbered) alkyl esters. The relative density of the second one is expected to be very similar if not equal to the first one.
2. SOURCE AND TARGET CHEMICALS
Both the target and the analogue are produced by esterification of fatty acids and lactate.
3. ANALOGUE APPROACH JUSTIFICATION
Since there is a significant overlap and similarity between the analogue measured and the target substance, read-across is here justified for density.

Conclusions:
Density of CERAPHYL 31 is between 0.90-0.92 at a temperature of 25°C.

Description of key information

Key value for chemical safety assessment

Relative density at 20C:
0.9

Additional information

The density is based on an experiment with C12 -15 alkyl lactates and can be considered as similar to the C12 -C16 (even numbers) alkyl lactates.
