Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Aquatic environment classification

According to the results of several reliable studies, acetone is readily biodegradable in water (ca. 91% biodegradation after 28 d; 10 -d window criterion fulfilled). In sea water, acetone was biodegraded by 76% after 20 d. The pass level of 60 % was barely failed. This indicates that biodegradation of acetone may be somewhat slower in sea water, but significant. Acetone is biodegradable under anaerobic conditions by adapted microorganisms (100% biodegradation within 4 days by cross-adapted microorganisms with acetate after a lag phase of 5 days; 74.3 - 95.4 % degradation).

The lowest acute EC/LC50 value in aquatic tests is the EC50 of 8800 mg/L for Daphnia magna. For algae/cyanobacteria a 8 d TT (NOEC)=530 mg/L is available (no EC50 available).

Due to the ready biodegradability of acetone and its low log Kow (-0.24) the substance is not classified as dangerous/hazardous for the environment according to Directive 67/548/EEC and according to the Regulation (EC) 1272/2008 on classification, labelling and packaging of substances and mixtures (CLP Regulation):

Basic data for classification and labelling:

Lowest reliable L(EC)50 value:                8800 mg/L for Daphnia magna

Lowest reliable long-term NOEC value:   530 mg/l for Mycrocystis aeruginosa (8 d TT)

Ready biodegradable                                yes

log Pow                                                   < 3

Special concern:                                       no

 

According to 67/548/EEC Annex 1:      not classified

 

Legal classification according to Commission Regulation (EU) No 286-2011 of 11 March 2011 amending, for the purposes of its adaptation to technical and scientific progress, Regulation (EC) No 1272/200:

not classified, no hazard statement

                                                      Reason:    L(E)C50 >100 mg/L; readily biodegradable, log Pow<4

Hazardous to the atmospheric environment:

(Hazardous to the ozone layer: This includes substances which are listed in Annex I to Regulation (EC) No 2037/2000 of the European Parliament and of the Council of substances that deplete the ozone layer (1) and its subsequent amendments):
acetone is not listed in Annex I of (EC) No 2037/2000.
