In this exposure band you would need information to demonstrate that environment hazard bands D and C do not apply to the chemical. Step 5 Case study: Environment hazard information for low risk in Exposure Band 3 (EB3) High volume surfactant - cosmetics Minimum hazard information Example needed for low risk Hazard band D PBT: not on a specified list AND Show that not P, not B or not T: not P: - measured ready biodegradability showing – Ready biodegradability test it degrades by > 70% within 28 days, or OECD TG 301 – shows chemical is ≥0.5 the BOD/COD ratio is OR readily biodegradable (so not PBT) not B: - measured partition coefficient of < 4.2 OR - measured bioconcentration factor of < 2000 OR - measured bioaccumulation factor of < 2000 OR not T:
