The read across substance Cashew Nutshell Extract, Decarboxylated, Distilled (“Distilled Grade”) is a UVCB which consists of cardanol (as the monoene, diene, triene and saturated side chain) with a typical content 83%, cardol (as the monoene, diene, triene and saturated side chain) with a typical content of 5%, 2-methyl-cardol (as the monoene, diene, triene and saturated side chain) with a typical content of 1%, C13 and unidentified phenolics with a typical content of 4%, C17 phenolics with a typical content of 2% and a polymeric content (including dimers, trimmers and larger molecules) with a typical content of 2%. The substance has a low water solubility (0.3 mg/l), a low vapour pressure (0.0005 Pa at 25oC) and a high octanol-water partition coefficient (log Kow = 6.2).

Any other information on results incl. tables

The read across substance is Cashew (Anacardium occidentale) Nutshell Extract, Decarboxylated, Distilled (“Distilled Grade”). The study for distilled grade is considered relevant for read across to distillation residue grade since the two substances:

•Contain the same constituents (cardanol, cardol, 2-methyl cardol, C13 and unidentified phenolics, C17 phenolics and polymeric species), generally in similar proportions.

•Have similar physico-chemical properties in terms of their water solubility, vapour pressure and octanol-water partition coefficient.
