PBT assessment

PBT assessment: overall result

PBT status:

the substance is not PBT / vPvB

Justification:

Acykglycinate GCK-11-T can be classified as readily biodegradable under aerobic conditions. A degradation rate of > 70 % was determined and the further validity criteria were also fulfilled. Based on the physico-chemical properties any significant bioaccumulation potential is not to be expected. These data indicate that the test item is not to be regarded as a substance being persistent (P/vP) and/or bioaccumulative (B/vB) according to the criteria of REACH Directive, Article 14.3 (d) and the Technical Guidance Document (TGD) R.11 of the European Chemicals Agency. Based on the results on short-term toxicity of acylglycinate GCK-11-T to aquatic organisms, the lowest (L(E)C50 was determined to be > 1 mg/L in short-term toxicity testing. In addition long-term toxicity data on algae are also available (NOEC=3.13 mg dry matter/L nominal) but this result should not be taken into account if this is not supported by results of at least another trophic level. The results with vertebrates and invertebrates indicate a significantly lower toxicity after exposure to the test item. Therefore it can be assumed that long-term toxicity will yield NOEC values > 0.01 mg/L. In consequence of the available and reliable data, the test item is not to be classified according to the Commission regulation (EU) No. 286/2011. Considering all available toxicity data, the test item is not to be regarded as a substance exhibiting PBT or vPvB properties according to the criteria of REACH Directive, Article 14.3 (d) and the Technical Guidance Document (TGD) R.11 of the European Chemicals Agency.
