Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Degradation (only key data needed for classification)

Biodegradation: readily biodegradable; 63-79% (CO2 evolution) after 28 d (OECD 301B)

Bioaccumulation (only key data needed for classification)

Bioaccumulation is expected to be low.

LogKow: -0.4 (EU Method A.8)

Aquatic acute toxicity (for each species only one key data used for classification)

For fish: 96 h, LC50 (Brachydanio rerio): 14.8 (test material) / L (4.44 mg act. ingr. /L)

For aquatic invertebrates: 48 h, EC50 (Daphnia magna): 7.76 act. ingr. mg/L

For algae/aquatic plant: 72 h, ErC50 (Pseudokirchneriella subcapitata):  1.7 mg act. ingr./L

Aquatic chronic toxicity (for each species only one key information)

For fish:                                              no data available on the substance itself.

For aquatic invertebrates:          21 d NOEC of 2.99 mg/L (100% substance), Daphnia magna

For algae/aquatic plant:              72 h, NOErC (Pseudokirchneriella subcapitata): 0.38 mg/L

Classification assigned according to DSD

Based on the data above, Betaines, C12-14 (even numbered)-alkyldimethyl, EC No. 931-700-2 is considered to be rapidly degradable and has low potential for bioaccumulation (log Kow < 3). The acute aquatic toxicity L(E)C50 is > 1mg/L for all three trophic levels. Hence, the substance does not need to be classified according to the Directive 67/548/EEC.

Classification assigned according to GLP

Betaines, C12-14 (even numbered)-alkyldimethyl, EC No. 931-700-2 is considered to be rapidly degradable. Valid chronic toxicity data are available to alga; the lowest NOEC is 0.38 mg/L (for Pseudokirchnerella subcapitata).Therefore, Betaines, C12-14 (even numbered)-alkyldimethyl needs to be classified and labelled as long-term aquatic hazard Chronic Cat. 3 according to the 2nd ATP of the Regulation (EC) No.1272/2008 (CLP).
