PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- 4-(cyclohexylamino)butane-1-sulfonic acid
- Type of composition:
- legal entity composition of the substance
- State / form:
- other: solid
- Reference substance:
- 4-(cyclohexylamino)butane-1-sulfonic acid
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Persistence assessment:
Based on the fact that the substance was not ready biodegradable under the stringent conditions of a ready biodegradability test, it fulfills the screening criterion for vP and P.
Bioaccumulation assessment:
As the substance has a log Kow lower than 4.5, the substance does not fulfill the screening criteria for B or vB.
Toxicity assessment:
Environmental toxicity: All acute L(E) C50 values are ≥ 0.1 mg/L and therefore this screening criterion for T is not fulfilled. The NOEC to algae is >1 mg/L. For a definitive classification as not T, a long-term aquatic NOEC ≥ 0.01 mg/L to fish and/or daphnia would be necessary. However, since the substance is not classified as B, it can already be concluded that the substance is not a PBT/vPvB substance.
