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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Density
Administrative data
Link to relevant study record(s)
- 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. - Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- GLP compliance:
- no
- Type of method:
- oscillating densitimeter
- Remarks:
- Mettler model DA-300 Density Meter
- Specific details on test material used for the study:
- Ceraphyl 41
- Key result
- Type:
- density
- Density:
- >= 0.9 - <= 0.92 g/cm³
- Temp.:
- 25 °C
- Conclusions:
- Density of dodecyl lactate approximates 0.9 at a temperature of 25°C, based on results of a test with C12-15 alkyl lactates.
Reference
Description of key information
The key value is based on read across from a mixture of alkyla lactates containing C12 to C15 chains.
Key value for chemical safety assessment
- Relative density at 20C:
- 0.9
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
