Criteria for assessing PBT properties are defined in Annex XIII, REACH
Regulation (EC) No. 1907/2006. Further details are laid down in ECHA
REACH Guidance on Information Requirements and Chemical Safety
Assessment; Chapter R.11: PBT Assessment (May 2008). The assessment of
PBT / vPvB properties is based upon a separate assessment for each
parameter (i.e. P or vP, B or vB and T). Substances are only assigned as
PBT or vPvB when they fulfill the criteria for all three properties
(persistency, bioaccumulation and toxicity in case of PBT substance) or
both criteria (i.e. very persistent and very bioaccumulative) in case of
Experimental results from different read-across source substances were
taken into account to complete the PBT/vPvB assessment for the sodium
sulfonate target substance (benzenesulfonic acid, di-C10-14-alkyl
derivs., sodium salts). Thus, the same conclusions regarding PBT
properties are drawn for the registered substance. In the following, the
read across procedure is not mentioned separately, however, the
assessment applies to benzenesulfonic acid, di-C10-14-alkyl derivs.,
sodium salts as well as to all read-across taken into account.
Due to results of ready-biodegradability tests, the read across source
substance, calcium sulfonate target substance (C10-C14) is considered as
persistent (P), but not very persistent (not vP). The B criterion
(bioaccumulative substance) is not fulfilled, due to the predicted
logPow of > 8 (estimated with KOWWIN v1.68, logPow: 8.8) and predicted
Bioconcentration factor (BCF) below the trigger value of 2000 L/kg
(70.79 L/kg). Due to the lack of toxicity observed in ecotoxicity
studies, also the T criterion is not fulfilled. Furthermore, no
classification exists as carcinogenic, mutagenic or toxic for
reproduction according to Regulation (EC) No. 1272/2008. The test
substance is neither classified as STOT RE category 1 or 2 so far. As
conclusion, benzenesulfonic acid, di-C10-14-alkyl derivs., sodium salts
fulfill only one relevant criterion (Persistency). Therefore, making all
allowances for regulatory parameters available, the target substance is
neither PBT nor vPvB.
