Endpoint:
biodegradation in water: simulation testing on ultimate degradation in surface water
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is highly insoluble in water
other:
Conclusions:
As detailed in the corresponding sections, potassium sodium tartrate has a ver low Kow and is a very soluble and readily biodegradable c4 dicarboxylic acid salt. Its negligible absorption potential, ready
degradability and low aquatic toxicity do not justify further study and allow waiving according to criteria in coloumn 2 of annex IX of regulation EC 1907/2006.
Executive summary:

As detailed in the corresponding sections, potassium sodium tartrate has a ver low Kow and is a very soluble and readily biodegradable

c4 dicarboxylic acid salt. Its negligible absorption potential, ready degradability and low aquatic toxicity do not justify further study and

allow waiving according to criteria in coloumn 2 of annex IX of regulation EC 1907/2006.

Endpoint:
biodegradation in water: sewage treatment simulation testing
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is readily biodegradable

Description of key information

As detailed in the corresponding sections, potassium sodium tartrate has a ver low Kow and is a very soluble and readily biodegradable c4 dicarboxylic acid salt. Its negligible absorption potential, ready

degradability and low aquatic toxicity do not justify further study and allow waiving according to criteria in coloumn 2 of annex IX of regulation EC 1907/2006.
