The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Justification for read-across from supporting substance RAV 7AT (diallyl 2,2'-oxydiethyl dicarbonate; CAS 142-22-3; EC 205-528-7): about 70 % of RAV 7NG (EC 700-483-4) consists of components that can be found in the commercial ADC grades known as RAV 7AT, Nouryset 200 and CR39. Merely from comparing the similar production processes of these two substances it is apparent that RAV 7AT and RAV 7NG are closely related to each other.  Finally, the physical-chemical, toxicological and ecotoxicological properties of RAV 7NG and RAV 7AT are almost equal and as a result, read across is justified.

Diallyl 2,2'-oxydiethyl dicarbonate, as the main ingredient of RAV 7NG, was determined to be readily biodegradable in two adequate (OECD 301D) ready biodegradability closed bottle tests (van Cinkel, 1993; RBM lnstituto di Ricerche Biomediche, 1994).

In addition one biodegradability test in soil was performed (no guideline followed; Williams, 1993), whereby the test substance 'diallyl 2,2'-oxydiethyl dicarbonate' was biologically degraded, chemically degraded, or volatilized in soil at 25 ± 1 °C to a level which was below the analytical detection limit (10 ppm) within 3 days [half life in soil < 3d at 25 ± 1°C].
