[Please provide information for all of the points below. Indicate if further information is included as attachment to the same record, or elsewhere in the dataset (insert links in 'Cross-reference' table)]
1. HYPOTHESIS FOR THE ANALOGUE APPROACH
[Describe why the read-across can be performed (e.g. common functional group(s), common precursor(s)/breakdown product(s) or common mechanism(s) of action]
The read-across target substance EP-49-10P2 is composed of a mixture of phosphate esters with bisphenol A diglycidylether (BADGE, CAS 1675-54-3, EC 216-823-5) that is dissolved in BADGE. The amount of esters in the target substance EP-49-10P2 ranges between 10% and 20%; the large rest is BADGE. Therefore, BADGE can be used as read-across source substance.
Based on the high content of BADGE (80-90%) and on the fact that the phosphate esters have higher molecular weights (MW > 1200 Da – approx. 3500 Da) and accordingly lower bioavailability it is concluded that the toxic and eco-toxic potential of EP-49-10P2 will be the same as that of BADGE. With the phosphate esters no hazardous functional groups are introduced.
2. SOURCE AND TARGET CHEMICAL(S) (INCLUDING INFORMATION ON PURITY AND IMPURITIES)
[Provide here, if relevant, additional information to that included in the Test material section of the source and target records]
3. ANALOGUE APPROACH JUSTIFICATION
[Summarise here based on available experimental data how these results verify that the read-across is justified]
No experimental data from toxicological or eco-toxicological studies with the target substance EP-49-10P2 are available for comparison of effects. However, based on the composition of EP-49-10P2 it is considered justified to make read-across from study results obtained with the read-across source substance BADGE in order to fulfil the information requirements for REACH registration of EP-49-10P2. - Reason / purpose for cross-reference:

Additional information
Justification for classification or non-classification
In the in vivo skin and eye irritation studies performed with the read-across source substance in rabbits only a low irritation potential was observed on skin and eyes. However, the substance is classified on a harmonised base: skin irritation 2 and eye irritation 2 (Regulation 1272/2008). This classification will be applied to the substance to be registered.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
