Conclusion on classification

According to Article 13 of Regulation (EC) No 1907/2006 "General Requirements for Generation of Information on Intrinsic Properties of substances", Information on intrinsic properties of substances may be generated by means other than tests e.g. from information from structurally related substances (grouping or read-across), provided that conditions set out in Annex XI are met. Annex XI, "General rules for adaptation of this standard testing regime set out in Annexes VII to X” states that “substances whose physicochemical, toxicological and ecotoxicological properties are likely to be similar or follow a regular pattern as a result of structural similarity may be considered as a group, or ‘category’ of substances. This avoids the need to test every substance for every endpoint”. Since read-across was applied for the substance, data will be generated from representative source substances to avoid unnecessary animal testing. Additionally, once the read-across approach is applied, substances will be classified and labelled on this basis.

Degradation

Biodegradation: readily biodegradable: 61% (O2 consumption) after 28 d

Bioaccumulation

Expert statement: Bioaccumulation is assumed to be low.  

Aquatic acute toxicity

Fish

96 h, LC50 (Danio rerio): > 10000 mg/L (nominal; no observed toxicological effects up to the water solubility limit); read-across

96 h, LC50 (Danio rerio): > 10000 mg/L (nominal; no observed toxicological effects up to the water solubility limit); read-across

48 h, LC50 (Leuciscus idus): > 10000 mg/L (nominal; no observed toxicological effects up to the water solubility limit); read-across

Aquatic invertebrates
48 h, EC50 (Daphnia magna): > 0.01 mg/L (measured, initial; no observed toxicological effects up to the water solubility limit; read-across

48 h, EL50 (Daphnia magna): > 100 mg/L (nominal; no observed toxicological effects up to the water solubility limit); read-across

Aquatic algae
72 h, ErL50 (Desmodesmus subspicatus): > 320 mg/L (nominal; no observed toxicological effects up to the water solubility limit); read-across

72 h, EC50 (Desmodesmus subspicatus): > 10 µg/L (meas. TWA; 100 mg/L nominal; no observed toxicological effects up to the water solubility limit); read-across

Aquatic chronic toxicity

Fish
No data available

Aquatic invertebrates
21 d, NOELR (Daphnia magna): ≥ 10 mg/L (nominal; no observed toxicological effects up to the water solubility limit); read-across

Aquatic algae
72 h, NOELR (Desmodesmus subspicatus): = 32 mg/L ; read-across

CLP

Based on the data above, Dub TGI 24 is considered to be readily biodegradable. No acute aquatic toxicity was observed up to the water solubility limit for fish, algae and daphnids. Valid chronic data are available with a NOELR (72 h) = 32 mg/L for aquatic algae. Therefore, the substance does not need to be classified and labelled as environmental hazard according to the 6th ATP of the Regulation (EC) No 1272/2008 (CLP).
