Description of key information

p-TSC is readily biodegradable. p-TSC is instantly hydrolysed to p-TS Acid, which is readily biodegradable as well.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Two ready biodegradability studies are available with p-TSC, both valid without restrictions. One is a MITI test (OECD 301C) which gave only partially degradation. In a Closed Bottle Test (OECD 301D) p-TSC was biodegraded 60% in 28 days and the substance is therefore readily biodegradable.

p-TSC is instantly hydrolysed to p-TS Acid. From literature it is known that p-TS Acid was completely degraded in 28 days, showing that p-TS Acid is readily biodegradable as well.
