Conclusion on classification

Classification Justification for TMAEE (CAS 93240-93-8) ‘mono-constituent’:

‘Mono-constituent’ - Official classification regarding environmental hazards

Aquatic compartment

According to Regulation (EC) 1272/2008 Annex VI Table 3.1, the substance is not classified as hazardous to the environment.

According to Regulation (EC) 1272/2008 Annex VI Table 3.2, the substance is not classified as hazardous to the environment.

 

‘Mono-constituent’: Self-classification

Aquatic compartment 

The classification of the TMAEE (CAS 93240 -93 -8) was based on experimental data from the substance itself and from read-across data from the structurally similar substance BDMAEE (CAS 3033-62-3):

Following GHS/CLP, the substance is not to be classified as acutely hazardous to the aquatic environment, based on the available acute data. Based on the available acute and chronic data, the substance is not to be classified as chronically hazardous to the aquatic environment.

 

Rationale:

According to the criteria outlined in Table 4.1.0(a) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) the substance is not to be classified as acutely hazardous to the aquatic environment as the lowest acute effect value is higher than 1 mg/L (algae: 72-h ErC50: 70.4 mg/L; BASF SE, 2019, report no.: 60E0034/19X015). 

Chronic toxicity data are available only for algae. Therefore, classification is based on the available chronic data for algae and acute toxicity data for the trophic levels not covered by chronic data (fish and aquatic invertebrates).

- Classification based on chronic toxicity data (algae): The substance is not rapidly degradable (see IUCLID chapter 5.2.1) and the ErC10 is > 1 mg/L (algae: 72-h ErC10 = 41 mg/L, BASF SE, 2019, report no.: 60E0034/19X015). According to the criteria outlined in Table 4.1.0(b) (i) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008), the substance is not to be classified as chronically hazardous to the aquatic environment.

- Classification based on acute toxicity data (fish and Daphnids): The lowest EC50 was determined for aquatic invertebrates (Read-across to BDMAEE, CAS 3033-62-3:48-h EC50 = 102 mg/L; RCC Ltd., 2008), the substance is not rapidly degradable (see IUCLID chapter 5.2.1), the log Kow is < 4, and the estimated BCF values are < 500 L/kg. According to the criteria outlined in Table 4.1.0(b) (iii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008), the substance is not to be classified as chronically hazardous to the aquatic environment.

In summary,based on the available acute and chronic data from TMAEE itself and from read-across data for BDMAEE (CAS 3033-62-3), the mono-constituent TMAEE (CAS 93240-93-8) is neither to be classified as acutely hazardous nor to be classified as chronically hazardous to the aquatic environment.

  

Atmospheric compartment

The substance is not in Annex I of Regulation (EC) 2037/2000 on substances that deplete the ozone layer.

The substance does not belong to the greenhouse gases listed in P Forster, PV Ramaswamy et al. Changes in Atmospheric Constituents and in Radiative Forcing. In: Climate Change 2007: The Physical Basis. Contribution of Working Group I to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change.

Classification Justification for relevant impurities of TMAEE (CAS 93240-93-8):

TMAEE (CAS 93240-93-8)is a mono-constituent substance that has a purity of 80-100 % (w/w). According to the ‘Guidance on the Application of the CLP-Criteria” (v4.1; ECHA, 2015) the relevant impurities of a substance still meeting the definition ‘mono-constituent’ may influence the classification of the substance. Therefore, the following impurities of TMAEE (CAS 93240‑93-8) identified as relevant constituents were additionally considered in terms of classification purposes:

 

- 2-[2-(dimethylamino)ethoxy]-N,N-dimethylethanamine (BDMAEE;CAS 3033 -62 -3); 1 – 9.99 %:

no harmonized CLP classification according to Regulation No (EC) 1272/2008 Annex VI; CLP self-classification: not classified

 

- 2-[2-(dimethylamino)ethoxy]ethanamine (ADAN, CAS 85322-63-0); 1 – 9.99 %:

no harmonized CLP classification according to Regulation No (EC) 1272/2008 Annex VI; CLP self-classification: not classified

 

- N-methyl-2-[2-(methylamino)ethoxy]ethanamine (ODAN, CAS 2620-27-1); 4 %:

no harmonized CLP classification according to Regulation No (EC) 1272/2008 Annex VI; CLP self-classification: not classified

 

- 2-[2-(dimethylamino)ethoxy]ethanol (DMAEE, CAS 1704-62-7);0 – 0.75 %:

no harmonized CLP classification according to Regulation No (EC) 1272/2008 Annex VI; CLP self-classification: not classified

 

 - N-Methylmorpholine (NMM, CAS 109-02-4); 0.1 – 0.5 %:

no harmonized CLP classification according to Regulation No (EC) 1272/2008 Annex VI; CLP self-classification: not classified

The data matrix used for classification purposes of the relevant constituents of TMAEE (CAS 93240-93-8) are given in ‘Read-Across Justification Document’-attachment (see e.g. IUCLID chapters 6.1.1, 6.1.3 etc.).

‘Relevant Constituents of TMAEE (CAS 93240-93-8)’ - Official classification regarding environmental hazards

According to Regulation (EC) 1272/2008 Annex VI Table 3.2, none of the relevant constituents are classified as hazardous to the environment.

 

‘Relevant Constituents of TMAEE (CAS 93240-93-8)’ - Self-classification

Following GHS/CLP, none of the relevant constituents of TMAEE (CAS 93240-93-8) is to be classified as acutely hazardous to the aquatic environment. Furthermore, none of the relevant components is to be classified as chronically hazardous to the aquatic environment.

 

Rationales:

BDMAEE (CAS 3033-62-3):

Regarding acute toxicity,algae turned out to be the most sensitive trophic level with a 72-h ErC50 of 24 mg/L (RCC Ltd., 2008). According to the criteria outlined in Table 4.1.0(a) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) the substance is not to be classified as acutely hazardous to the aquatic environment as the lowest acute effect value is higher than 1 mg/L.

Chronic toxicity data are available only for algae. Therefore, classification is based on the available chronic data for algae and acute toxicity data for the trophic levels not covered by chronic data (fish and aquatic invertebrates).

Classification based on chronic toxicity data (algae): The substance is not rapidly degradable and the ErC10 is > 1 mg/L (algae: 72 -h ErC10 = 5 mg/L). According to the criteria outlined in Table 4.1.0(b) (i) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008), the substance is not to be classified as chronically hazardous to the aquatic environment.

Classification based on acute toxicity data (fish and Daphnids): The lowest EC50 was determined for aquatic invertebrates (48-h EC50 = 102 mg/L), the substance is not rapidly degradable, the log Kow is < 4. According to the criteria outlined in Table 4.1.0(b) (iii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008), the substance is not to be classified as chronically hazardous to the aquatic environment.

In summary, based on the available acute and chronic toxicity data BDMAEE (CAS 3033-62-3) is neither to be classified as acutely hazardous, nor to be classified as chronically hazardous to the aquatic environment.

ADAN (CAS 85322-63-0):

No experimental data are available for this relevant constituent. The assessment is, therefore, based on calculated (Q)SAR data.

Regarding acute toxicity,the lowest estimated EC/LC50 value available is a LC50 of >100 mg/L for fish (SarPy/IRFMN v1.0.2; [86]); the substance was within the model’s applicability domain. According to the criteria outlined in Table 4.1.0(a) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) the substance is not to be classified as acutely hazardous to the aquatic environment as the lowest acute effect value is higher than 1 mg/L.

Chronic toxicity data are not available. Therefore, classification is based on the available acute toxicity data for the trophic levels not covered by chronic data (fish, aquatic invertebrates and algae). The lowest estimated EC/LC50 value available is a LC50 of >100 mg/L for fish (SarPy/IRFMN v1.0.2; [86]); the substance was within the model’s applicability domain. The substance is estimated to be not rapidly degradable, the log Kow is estimated to be < 4; the BCF is estimated to be < 500 L/kg.
