Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Conclusion on classification

Brief description of the data relevant for classification

Degradation

Biodegradation:                 Readily biodegradable: 62.5% of CO2 evolution (OECD 301 F)

Bioaccumulation

Expert statement:               Bioaccumulation is expected to be low.

Aquatic acute toxicity

For fish:                             96 h, LC50 (Danio rerio): no effects up to the limit of water solubility

For aquatic invertebrates: 21 d, EL50 (Daphnia magna): 23.9 mg/L

For algae/aquatic plants:   72 h, ErL50 (Pseudokirchneriella subcapitata): 58.8 mg/L

Aquatic chronic toxicity

For fish:                              no data available

For aquatic invertebrates:    21 d, NOELR (Daphnia magna): 10 mg/L

For algae/aquatic plant:     72 h, ErL10 (Pseudokirchneriella subcapitata): 19.05 mg/L

Conclusion on classification

CLP:

Based on the data above, Sorbitan monolaurate, ethoxylated is considered to be rapidly degradable. The acute aquatic toxicity L(E)C50 values are > 10 mg/L. Therefore, Sorbitan monolaurate, ethoxylated does not need to be classified and labelled as acute aquatic hazard according to the 2nd ATP of the Regulation (EC) No.1272/2008 (CLP).

Valid chronic toxicity data are available for invertebrate and algae - the lowest NOECs are > 1 mg/L. Therefore, Sorbitan monolaurate, ethoxylated does not need to be classified and labelled as long-term aquatic hazard according to the 2nd ATP of the Regulation (EC) No.1272/2008 (CLP).

DSD:

Based on the data above, Sorbitan monolaurate, ethoxylated is considered to be rapidly degradable and have low potential for bioaccumulation. The acute aquatic toxicity L(E)C50 values are > 10 mg/L for fish, invertebrates and algae. Therefore, Sorbitan monolaurate, ethoxylated does not need to be classified and labelled as environmental hazard according to Directive 67/548/EEC.
