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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
- Endpoint:
- biodegradation in water: ready biodegradability
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Justification for type of information:
- See the attached document as the justification of the read-across.
- Reason / purpose for cross-reference:
- read-across source
- Specific details on test material used for the study:
- Identification : MALTITOL
CAS No. : 585-88-6
EC No. : 209-567-0
Batch ELEL7
Appearance White powder - Key result
- Parameter:
- % degradation (CO2 evolution)
- Value:
- 73 - 81
- Sampling time:
- 28 d
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Conclusions:
- The biodegradation of maltitol is between 73%-81% in OECD 301B test. Maltitol is considered as readily biodegradable.
- Executive summary:
Taking into account the structure similarity between the target substance "maltitol" and the source substance "Glucose syrups wheat hydrolyzed", the maltitol was considered as readily biodegradable with a percentage of biodegradation between 73%-81% in OECD 301B test. This is a worse case approach since the source substance which contains a polymeric fraction should be less biodegradable than the maltitol.

Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
- Type of water:
- freshwater
Additional information
Taking into account the structure similarity between the target substance "maltitol" and the source substance "Syrups, wheat, hydrolyzed starch", the maltitol is considered as readily biodegradable with a percentage of biodegradation between 73%-81% in OECD 301B test. This is a worse case approach since the source substance which contains a polymeric fraction should be less biodegradable than maltitol.
Moreover this result was supported by the Maltitol biodegradation estimated with the QSAR "BIOWIN v4.10 (EPI Suite v4.11)". Indeed Biowin 1 and 2 indicate that Maltitol biodegrades fast, and Biowin 5 and 6 consider that maltitol is readily biodegradable.
