PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The PBT assessment for C12-14 MIPA (CAS 85681-66-9) is based on the criteria set out in the "Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment" (ECHA, 2014).
Persistence (P) Assessment:
A substance is not considered to be persistent if it can be demonstrated that it has potential to degrade (via photolysis, hydrolysis and/or biodegradation). Studies using standardized test guidelines available for C12-14 MIPA (CAS 85681-66-9) demonstrated the ready biodegradability of the substance (83%) after 28 days based on O2 consumption (OECD 301D). Therefore, C12-14 MIPA (CAS 85681-66-9) does not meet the Persistent (P) or very Persistent (vP) criteria.
Bioaccumulation (B) Assessment:
The value of log Pow was determined to be < -1.578. Available data indicate that C12-14 MIPA (CAS 85681-66-9) has a very low potential for bioconcentration and the substance will not accumulate to significant levels in the aquatic environment. Therefore, C12-14 MIPA (CAS 85681-66-9) 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 data on daphnids was 0.12 mg/L. This value exceeds the toxicity criterion and therefore, C12-14 MIPA (CAS 85681-66-9) is not considered as a toxic substance regarding ecotoxicological endpoints.
Human Health Toxicity:
Carcinogenicity: the available data on C12-14 MIPA (CAS 85681-66-9) do not warrant classification for carcinogenicity under GHS/CLP.
Mutagenicity: the available data indicate that C12-14 MIPA (CAS 85681-66-9) is not genotoxic or mutagenic and do not warrant classification for carcinogenicity under GHS/CLP.
Reproductive Toxicity: there is no evidence that C12-14 MIPA (CAS 85681-66-9) 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 GHS/CLP.
Chronic toxicity: due to the results of the relevant mammalian toxicity studies C12-14 MIPA (CAS 85681-66-9) is not classified as STOT RE.
C12-14AS MIPA (CAS 85681-66-9) does not meet the (T) criteria.
The substance is considered not to be PBT or vPvB on the basis of the provided relevant data.
