Description of key information

Half life period of Hydroxyaluminium distearate  in water is observed to be 37.5  days (900 hrs.) while in sediment it is 337.5 days (8100 hrs). Based on these half life values of Hydroxyaluminium distearate , it is concluded that the chemical is not persistent in water and sediment. 

Key value for chemical safety assessment

Half-life in freshwater:
37.5 d
at the temperature of:
25 °C
Half-life in freshwater sediment:
337.5 d
at the temperature of:
25 °C
