REPORTING FORMAT FOR THE ANALOGUE APPROACH
[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

The read across analogue substance is one of the the individual component substances of the UVCB registration substance. On the basis of structural similarity it is considered that the individual component will have similar surface active properties as the overall UVCB substance.

2. SOURCE AND TARGET CHEMICAL(S) (INCLUDING INFORMATION ON PURITY AND IMPURITIES)
Read across source-bis(2-ethylhexyl) terephthalate. EC 229-176-9
Read across target (registration substance)-Reaction product of terephthalic acid, 2-ethlyhexanol and 1-butanol. EC 946-149-3


3. ANALOGUE APPROACH JUSTIFICATION
On the basis of structural similarity it is considered that the individual component will have similar surface active properties as the overall UVCB substance.
