PBT assessment: overall result

PBT status:
the substance is not PBT / vPvB

The PBT assessment for CAS 1394155-71-5 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:

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). Several studies using standardized test guidelines are available for CAS 1394155-71-5 that could all demonstrate the ready biodegradability of the substance (77% after 30 days based on DOC removal, OECD 301 D). Therefore CAS 1394155-71-5 does not meet the Persistent (P) or very Persistent (vP) criteria.


Bioaccumulation (B) Assessment:

The value of log Pow was determined to be -0.69. The available data indicates that CAS 1394155-71-5 has a very low potential for bioconcentration and the substance will not accumulate to significant levels in the aquatic environment. Therefore, CAS 1394155-71-5 does not meet the Bioaccumulative (B) or very Bioaccumulative 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 0.204 mg/L. This value exceeds the toxicity criterion and therefore, CAS 1394155-71-5 is not considered as a toxic substance regarding ecotoxicological endpoints.

Human Health Toxicity:

Carcinogenicity: the available data on CAS 1394155-71-5 do not warrant classification for carcinogenicity under Directive 67/548/EEC or GHS/CLP.

Mutagenicity: the available data indicate that CAS 1394155-71-5 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 CAS 1394155-71-5 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, CAS 1394155-71-5 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.
