Additional information

Screening tests on biodegradation in water indicate that phthalic acid is readily biodegradable, and inherently biodegradable.

Phthalic acid shows 74% degradation after 30 days in a closed bottle test, which is comparable to the OECD TG 301 D (Bayer, 1973). The inherent biodegradability of phthalic acid was assessed according to the EU Method C.9 (Biodegradation: Zahn-Wellens Test). Phthalic acid showed > 90% degradation after 4.5 days (Zahn, 1980).
