Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- Aluminum hydroxide diacetate
- Type of composition:
- legal entity composition of the substance
- State / form:
- solid: particulate/powder
- Reference substance:
- Aluminum hydroxide diacetate
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Conclusion on persistence: not vP and P
The target chemical is considered to be ready biodegradable, since four publications conducted with the source chemical (acetic acid) indicate its biodegradability (reference 5.2.1-1 to 5.2.1-4). Thus, the P criterion is not fulfilled.
Conclusion on bioaccumulation: not vB and B
It was not possible to determine experimentally the partition coefficient using the individual solubilities of the test item in water and n-octanol. The program KOWWIN (part of EPI Suite) was used for calculating the log Pow of the test item. The calculated value was -0.63. Therefore, the B criterion is not fulfilled.
Conclusion on toxicity: not T
One long-term toxicity study in aquatic organisms is available, i. e. for algae. The EC50 and EC10 based on growth rate were determined to be 1.02 mg/L and 0.72 mg/L (hydrated substance, mean measured), and 0.92 mg/L and 0.66 mg/L (calculated value for anhydrous substance), respectively. The substance is not classified as carcinogenic, germ cell mutagenic or toxic for reproduction according to Regulation (EC) No 1272/2008; and there is no evidence of specific target organ toxicity after repeated exposure according to Regulation (EC) No1272/2008. Thus, the T criterion is not fulfilled based on the available data.
Reference
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.
