Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT assessment
Administrative data
Assessed Substance
- Assessed substance:
- substance itself
- PBT status of the assessed substance:
- the substance is not PBT / vPvB
Results of detailed PBT / vPvB assessment
Persistence
Evidence of non-P / non-vP properties
Screening criteria
- Not P and not vP based on: readily biodegradable
- Remark:
- With respect to the persistency the predicted (EPI suit) Biowin 3 degradation rate is 2.9 and is a strong indication that the substance will biodegrades fast (days – weeks). The Biowin 2 probability is above 0.5 (estimated probability 0.82) again giving a further indication that the substance will biodegrade fast. However the Biowin 5 (MITI Linear model) and the Biowin 6 (MITI non-linear model) has a probability of 0.45 and 0.46 respectively and the low probability below 0.5 is an indication that the substance will not readily biodegrade. The criteria for P or vP is that either both Biowin 2 and Biowin 3 indicate persistence or both Biowin 6 and Biowin 3 indicate persistence. Neither of these two criteria is met and so the overall assessment of the EPI suit predictions is that the substance is not P or vP.
Criteria based on Annex XIII of REACH
Conclusion
- Conclusion on P / vP properties:
- not P/vP
Bioaccumulation
Evidence of non-B / non-vB properties
Screening criteria
- Not B and not vB based on: Log Kow ≤ 4.5
- Remark:
- The substance has a very low Log Kow measured at: Log Kow 0.32. This low Log Kow is an indication that the substance is likely to remain in water indicating not be B or vB. In addition the bioaccumulation factor (predicted from valid EPI suit) is extremely low at 3.162 L/kg. This is well below the > 2000 L/kg threshold which again indicated not B or vB.
Criteria based on Annex XIII of REACH
Conclusion
- Conclusion on B / vB properties:
- not B/vB
Toxicity
Evidence of non-T properties
Criteria based on Annex XIII of REACH
- Not T based on:
- and substance is not classified as carcinogenic (category 1 or 2), mutagenic (category 1 or 2), or toxic for reproduction (category 1, 2 or 3) according to Directive 67/548/EEC or carcinogenic (category 1A or 1B), germ cell mutagenic (category 1A or 1B), or toxic for reproduction (category 1A, 1B or 2) according to Regulation EC No 1272/2008:
- Cyclopropane carbonyl chloride is is not classified as carcinogenic (cat 1 or 2), mutagenic (category 1 or 2) or toxic for reproduction (category 1, 2 or 3) according to Directive 67/548/ECC or carcinogenic (category 1A or !B), germ cell mutagenic (category 1A or 1B), or toxic for reproduction (category 1A, 1B or 2) according to Regulation EC No 1272/2008. Therefore there is no current indication that the substance is to be classified as toxic.
Evidence of T properties
Conclusion
- Conclusion on T properties:
- not T
