Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

Description of key information

DMMP is of low acute oral toxicity after gavage application. LD50 values were reported to be higher than 5000 mg/kg bw in several reliable studies. It was also found to be of low acute dermal toxicity as tested with doses of 2000 mg/kg bw. No mortality was observed in an acute inhalation study at the dose of > 2589 mg/m³ air . All studies were performed in a design sufficiently similar or identical to the current OECD testing guideline.

Key value for chemical safety assessment

Additional information

Acute oral toxicity values were above 5000 mg/kg bw with the exception of two reports that were found in the US TSCA8e inventory by CAS-no search. The actual identifier in the reports do not allow assessment of the purity or composition of the test material. The fairly low LD50 values in the range of 1000 mg/kg bw is in contrast to all other well documented acute and repeated dose toxicity data. Therefore, the data is not taken into account for classification and labelling.

The following reports are concerned:

TSCATS (1992a). Report on oral LD50 in rats. CAP ID No. 8ECAP-0014, OTS 0540431. Testing laboratory: Cannon Laboratories, Inc., P. O. Box 3627, Reading, Pa. 19605. Report no.: 8E-2383. Owner company: Mobil Chemical Company. Study number: MTCR-129-78. Report date: 1978-08-24.

TSCATS (1992b). Report on oral LD50 in rats. CAP ID No. 8ECAP-0014, OTS 0540431. Testing laboratory: Cannon Laboratories, Inc., P. O. Box 3627, Reading, Pa. 19605. Report no.: 6E-9831. Owner company: Mobil Chemical Company. Study number: MTCR-93-76. Report date: 1976-12-10.

Justification for classification or non-classification

Dangerous Substance Directive (67/548/EEC)

The available studies are considered reliable and suitable for classification purposes under 67/548/EEC. As a result the substance is not considered to be classified for acute oral, dermal or inhalation toxicity under Directive 67/548/EEC, as amended for the 28th time in Directive 2001/59/EC.

Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008

The available experimental test data are reliable and suitable for classification purposes under Regulation 1272/2008. As a result the substance is not considered to be classified for acute oral, dermal or inhalation toxicity under Regulation (EC) No. 1272/2008.
