PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- Lauryl betaine
- Type of composition:
- legal entity composition of the substance
- State / form:
- liquid
- Reference substance:
- Lauryl betaine
- Reference substance:
- Lauryl betaine
- Reference substance:
- Lauryl betaine
- Reference substance:
- Lauryl betaine
- Reference substance:
- Lauryl betaine
- PBT status:
- the substance is not PBT / vPvB
- Justification:
Persistant- Lauryl betaine is readily biodegradable according to an OECD 301B study (73 -84% (CO2 evolution) after 28 d) and as such does not persist in the environment. Thus lauryl betaine does not meet the screening criterion for persistence and it is not considered to be P or vP.
Bioaccumulative- The measured Log Pow is -0.07. The available information indicates that lauryl betaine has a very low potential for bioconcentration and they will not accumulate to significant levels in aquatic organisms. Therefore lauryl betaine is not considered to be bioaccumulative - not B or vB.
Toxic-the toxicity criterion is not met for lauryl betaines as the acute aquatic toxicity L(E)C50 is >1 mg/L. Not T or vT
