Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusion on classification

Classification based on biodegradation, bioaccumulation and acute data

Degradation

 

Biodegradation:      28% within 28 d (OECD 301D)

 

Bioaccumulation

LogKow:                  -3.63 (EU Method A.8 (Partition Coefficient)

 

Aquatic acute toxicity

For fish: LC50(96 h) > 100 mg/L, (OECD 203, limit test, Oncorrhynchus mykiss)

For aquatic invertebrates: EC50(48 h) > 100 mg/L (OECD 202, limit test, Daphnia magna)

For algae: ErC50(72 h) = 25 mg/L, (OECD 201, Desmodesmus subspicatus)

 

Aquatic chronic toxicity

Valid NOECs are not available.

 

Based on the data above, sulfopropyl acrylate (SPA) is considered to be not rapidly degradable and indicate a low potential for bioaccumulation.

 

Classification and labelling according to Regulation (EC) No.1272/2008 (CLP) and Regulation (EU) No. 286/2011 (6thATP):

The acute classification follows from acute aquatic toxicity data > 1 mg/L in fish, invertebrates and algae. Therefore, (3-Sulfopropyl)- acrylate, potassium salt does not need to be classified for acute (short-term) aquatic hazard.

The chronic classification is based in the absence of chronic data with respect to acute aquatic toxicity data > 10 to ≤ 100 mg/L for algae and because the substance is not rapidly degradable although the substance indicate a low potentiel of bioaccumulation. Only an ErC10(72 h) of 1.61 mg/L is available, derived from a toxicity test to algae (Desmodesmus subspicatus). Since in this test a NOEC could not be calculated due to mathematical reasons and the derived ErC10 was in the threshold range of the classification limit, this value could not be taken into account for classification.

Therefore, SPA needs to be classified for chronic (long-term) aquatic hazard with Category Chronic 3.

 

M-factor for acute aquatic toxicity: no classification for acute aquatic toxicity

M-factor for chronic aquatic toxicity: not applicable due to absence of chronic data
