PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- cis-2-methyl-4-propyl-1,3-oxathiane
- Type of composition:
- boundary composition of the substance
- State / form:
- liquid
- Reference substance:
- cis-2-methyl-4-propyl-1,3-oxathiane
- Name:
- cis-2-methyl-4-propyl-1,3-oxathiane
- Type of composition:
- legal entity composition of the substance
- State / form:
- liquid
- Related composition:
- cis-2-methyl-4-propyl-1,3-oxathiane
- Reference substance:
- cis-2-methyl-4-propyl-1,3-oxathiane
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The substance does not meet the criteria for PBT or vPvB. The substance is potentially persistent ('not readily biodegradable'), however the substance is not considered bioaccumulative (BCF << 2000) and is not known to be toxic.
The substance constituent has been tested for biodegradability at the screening level through a structural analogue and based on structural similarity and supporting predictions rapid (bio)degradation is not achieved within 28 days. The substance has a log Pow < 3.0 and consequentially a BCF < 500 L/Kg and BCF << 2000 L/Kg. The conclusion for the substance is that it is not bioaccumulative in accordance with ECHA Guidance on Information Requirements and Chemical Safety Assessment, Chapter R.11. While a full dataset on chronic or acute aquatic toxicity data is not available, the substance is not considered toxic based on consideration of the available measured and predicted acute aquatic toxicity effects for all constituents (for daphnia, algae, and fish per OECD 201, 202, and 203), they do not fulfil the screening criteria for toxicity based on the EC50 values of these studies. Based on the available information, the substance is not classified as having CMR properties, nor does it show other evidence of the toxicity criteria based on a sub-acute toxicity study in animals.
In conclusion, the substance is considered neither PBT nor vPvB.
- Likely routes of exposure:
Not applicable. Substance is not PBT/vPvB.
