Description of key information

Additional information

The described 'red disazo condensation pigment' is practically insoluble and has a negligible vapour pressure. Hence, distribution into the compartments water and air are unlikely and in consequence abiotic degradation processes like hydrolyses and photodegradation are not relevant under environmental conditions. If the pigment will be released into the environment, the substance may be found in the compartments sediment and soil.

Based on the molecular size, cellular uptake of the pigment is unlikely. Therefore bioaccumulation in biota is not expected. Furthermore intracellular biodegradation, which is the main degradation route of bacteria, is probably low. Hence the substance is likely to persist in the environment.

In Article 13 of Regulation (EC) No 1907/2006, it is laid down that information on intrinsic properties of substances may be generated by means other than tests, provided that the conditions set out in Annex XI (of the same Regulation) are met. Furthermore according to Article 25 of the same Regulation testing on vertebrate animals shall be undertaken only as a last resort. 

According to Annex XI of Regulation (EC) No 1907/2006 (Q)SAR results can be used if (1) the scientific validity of the (Q)SAR model has been established, (2) the substance falls within the applicability domain of the (Q)SAR model, (3) the results are adequate for the purpose of classification and labeling and/or risk assessment and (4) adequate and reliable documentation of the applied method is provided. 

For the assessment  (Q)SAR results were used for aerobic biodegradability in water.The criteria listed in Annex XI of Regulation (EC) No 1907/2006 are considered to be adequately fulfilled and therefore the endpoint(s) sufficiently covered and suitable for risk assessment. Therefore, further experimental studies on aerobic biodegradability in water are not provided.
