reaction mass of isomers of: C7-9-alkyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate

Endpoint summary

Additional information

Experimental studies on hydrolytic effects demonstrated that the substance does undergo hydrolysis at environmentally relevant pH’s, with a half life of 10.8 days at pH 4, 182 days at pH7 and 14.1 days at pH 9. As such, some minor degradation is anticipated via this route. Studies on direct phototransformation in water are not available, but it is assumed on the basis of chemical structure and nature of use that the substance is not degraded by direct photolysis. It is concluded, therefore, that abiotic processes would contribute to the depletion of the substance within the environment, although this is likely to be a slow process
