Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on the aquatic toxicity data, the test substance is not classified as hazardous to the environment in accordance with Regulation (EC) No 1272/2008
Conclusion on classification
The results from the acute aquatic toxicity studies (performed at the limit of solubility of HMX) are as follows:
96 hr LC 50 (for fish) > 15 mg/l (nominal concentration)
48 hr EC 50 (for daphnia) > 15 mg/l (nominal concentration)
72 hr ErC 50 (for algae) > 2.61 mg/l (measured concentration)
Based on these results, the lowest acute E(L)C50 is higher than 1 mg/L. Therefore, the registered substance is not classified as acute 1 to aquatic organisms in accordance with the classification of the CLP (Regulation (EC) No 1272/2008).
In addition, adequate chronic toxicity data available for fish, crustacea and algae:
32 d NOEC (for fish) > 3.3 mg/l (measured concentration)
28 d NOEC (for Daphnia) >3.9 mg/l (measured concentration)
72 hr ErC 10 (for algae) > 2.61 mg/l (measured concentration)
CLP Classification proposal:
It is proposed to compare submission substance dataset to CLP environmental criteria laid down in CLP Regulation:
- Acute aquatic hazard: not classified. Reasoning: lowest E(L)C50 greater than 1 mg/L.
- Chronic aquatic hazard: not classified. Reasoning: Non-rapidly degradable substance for which there are adequate chronic toxicity data available, lowest chronic NOEC or EC10 value greater than 1 mg/L.
Conclusion on classification:
According to the CLP Regulation 1272/2008 the substance HMX is not classified hazardous to the aquatic environment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
