Description of key information
Additional information
Stability
Pthalic acid is considered to be stable towards hydrolysis.
An estimated half-life of 12.7 days in air was calculated with the AOP Program v1.91 of EPI-Suite. The experimentally determined half-life in sea water was 0.93 hours at 50°C.
Biodegradation
Phthalic acid is readily biodegradable with 74 % within 30 days. Biodegradation was confimed in a read across approach of phthalic anhydride which hydrolysed within seconds to phthalic acid. For phthalic anhydride the biodegradation was 85 % whithin 14 days.
Bioaccumulation
The estimated BCF of 3.16 indicates no affinity of phthalic acid for bioaccumulation.
Adsorption
The experimentally determined Koc was in a range of 2 -31, and hence no tendency for adsorption on soil is expected. Since the determination of the Koc was performed at different pH-values it is concluded that predication is valid even for the ionised substance.
Distribution The calculated Henry´s Law Constant was 2.21E-7 Pa m³/mole, therefore no potential to leave the aqueous phase is given. The distribution of phthalic acid in a "unit world" was calculated according to the Mackay fugacity model level I based on the physico-chemical properties. The main target compartment for phthalic acid is water of 99.9 %.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).
