Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation:

- Readily biodegradable: 67.75% (based on ThOD NH3) after 28 d (OECD 301 D) and 80% (CO2 evolution) after 28 d (OECD 301 B)

Bioaccumulation potential:

- log Kow: -3.2 (EU Method A.8)

 

Aquatic acute toxicity:

- to fish: LC50 (96 h) = 0.76 mg a.i./L (OECD 203, Oncorhynchus mykiss)

- to Crustacea: EC50 (48 h) = 0.68 mg a.i./L (OECD 202, Daphnia magna)

- to Algae: ErC50 (72 h) = 0.0012 mg a.i./L (OECD 201, Pseudokirchneriella subcapitata)

 

Aquatic chronic toxicity

- to fish: no data available

-  to Crustacea: NOEC (21 d) = 0.0095 mg a.i./L (OECD 211, Daphnia magna)

- to Algae: ErC10 (72 h) = 0.00074 mg a.i./L (OECD 201, Navicula pelliculosa)

 

Classification:

Since the active substance is only market as a 40-42% w/w aqueous solution and no dry product is isolated during the manufacturing process, the ecotoxicological effect concentrations of the 40-42% technical sodium dimethyldithiocarbamate solution in water were used to derive the classification.

 

Based on the data above, sodium dimethyldithiocarbamate is considered to have low potential for bioaccumulation and is readily biodegradable. The acute effect values (LC50/EC50) for the aquatic toxicity to all three trophic levels are < 1 mg/L and the lowest effect value for long-term aquatic toxicity is < 0.01 mg/L. Therefore, sodium dimethyldithiocarbamate is classified and labelled as environmental hazard Acute Cat . 1 (H400) and Chronic Cat. 1 (H410) according to the Regulation (EC) No. 1272/2008 (CLP) and the Regulation (EU) No. 286/2011.

 

M-factor for acute aquatic toxicity: 100

M-factor for chronic aquatic toxicity: 10
