PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The PBT assessment of C8-18AS Mg & TEA (CAS 85586-38-5) is based on the criteria set out in the "Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment" (ECHA, 2008).
Persistence (P) Assessment:
One biodegradation test performed according to OECD guideline 301 is available indicating the substance to be readily biodegradable. Therefore, C8-18AS Mg & TEA (CAS 85586-38-5) does not meet the Persistent (P) or very Persistent (vP) criteria.
Bioaccumulation (B) Assessment:
The log Pow value was determined to be ≤ -0.62. The available data indicate that C8-18AS Mg & TEA (CAS 85586-38-5) has a very low potential for bioconcentration and the substance will not accumulate to significant levels in the aquatic environment. Therefore, C8-18AS Mg & TEA (CAS 85586-38-5) does not meet the Bioaccumulative (B) or very Bioaccumulative (vB) criteria.
Toxicity (T) Assessment:
Environmental Toxicity:
According to Annex XIII of REACH Regulation (EC) No 1907/2006, a substance is considered to be toxic in terms of PBT criteria if long-term NOEC values for aquatic organisms are lower than 0.01 mg/L. The NOEC value based on chronic experimental data on daphnids was 0.22 mg/L. This value exceeds the toxicity criterion and therefore, C8-18AS Mg & TEA (CAS 85586-38-5) is not considered as a toxic substance regarding ecotoxicological endpoints.
Human Health Toxicity:
Carcinogenicity: the available data on C8-18AS Mg & TEA (CAS 85586-38-5) do not warrant classification for carcinogenicity under Directive 67/548/EEC or GHS/CLP.
Mutagenicity: the available data indicate that C8-18AS Mg & TEA (CAS 85586-38-5) is not genotoxic or mutagenic and do not warrant classification for carcinogenicity under Directive 67/548/EEC or GHS/CLP.
Reproductive Toxicity: There is no evidence that C8-18AS Mg & TEA (CAS 85586-38-5) causes reproductive or developmental toxicity. The available data indicate that members of the alkyl sulfate category are not toxic to reproduction and do not warrant classification under Directive 67/548/EEC or GHS/CLP.
Chronic toxicity: due to the results of the relevant mammalian toxicity studies, C8-18AS Mg & TEA (CAS 85586-38-5) is not classified as Xn, R48 or STOT RE.
The substance is considered not to be PBT or vPvB on the basis of the provided relevant data.
