Conclusion on classification

Classification related key information

Water solubility: < 0.15 mg/L (equal to < 5 µg Al/L)

Biodegradation in water: 81.2% after 29 days based on CO2 evolution (OECD 301 B)

log Pow: cannot be measured because the substance has very low water solubility

BCF = 215 at pH 5.3; 35 at pH 7.2 (Salvelinus fontinalis); no potential for bioaccumulation

 

Acute toxicity:

- to fish: no toxicity up to the water solubility limit; LC50 (96h) > 100 mg/L (WAF, Danio rerio, OECD 203)

- to invertebrates:  no toxicity up to the water solubility limit; EC50 (48h) > 100 mg/L (WAF, Daphnia magna, OECD 202)

- to algae: no toxicity up to the water solubility limit; ErC50 (72h) > 100 mg/L (WAF, Pseudokirchnerella subcapitata, OECD 201; read-across from CAS 21645-51-2 and CAS 57-10-3)

 

 Chronic toxicity:

- to fish: no toxicity up to the water solubility limit; NOEC > 0.15 mg/L (equal to 5 μg Al/L)

- to invertebrates: no toxicity up to the water solubility limit; NOEC > 0.15 mg/L (equal to 5 μg Al/L)

- to algae: no toxicity up to the water solubility limit; NOEC (72h) ≥ 100 mg/L (WAF, Pseudokirchnerella subcapitata, OECD 201; read-across from CAS 21645-51-2 and CAS 57-10-3)

 

Classification justification according to CLP

Based on the data above, there is no acute toxicity observed up to the limit of water solubility for fish, algae and Daphnia. Fatty acids, C16-18 (even numbered), aluminum salts do not need to be classified and labeled as acute aquatic hazard according to the 2nd ATP of Regulation (EC) No.1272/2008 (CLP).

Fatty acids, C16-18 (even numbered), aluminum salts are considered to be rapidly degradable. Valid chronic toxicity data are available for fish, daphnia and algae and show no toxicity up to the water solubility limit. Therefore fatty acids, C16-18 (even numbered), aluminum salts do not need to be classified and labeled as environmental hazard according to the 2nd ATP of Regulation (EC) No.1272/2008 (CLP).

 

Classification justification according to DSD

Based on the data above, fatty acids, C16-18 (even numbered), aluminum salts are considered to have low potential for accumulation and is rapidly degradable. The acute aquatic toxicity L(E)C50 are above 100 mg/L. Therefore fatty acids, C16-18 (even numbered), aluminum salts do not need to be classified and labeled as environmental hazard according to Directive 67/548/EEC.
