Focus group for tool:Formulators FORMULATORS own use uses by their customers
Key use of ES-modifier 1. Harmonisation (OC’s and RMM’s) of ES’s received from different suppliers. 2. Scale the ES according to specific needs (eg. customer request) ES Substance 1 Duration: 2 hrs Ventilllation: No RMM: Mask ES Substance 2 Duration: 8 hrs Ventillation RMM: No ES Preparation Duration: ? Ventillation:? RMM: ? + = Duration: 8 hrs ES Preparation Duration: 4 hrs RMM: No Customer conditions

How to useES-modifier • Choose lifecycle stage (and user group) • Describe overall use according to DoU (Descriptors of Use) • Insert substance data (directly/plug-in)(Today ES-Modifier is substance based; future plans for preparations) • Choose models(Default models are Ecetoc TRA and EUSES) • Describe specific details of use • Make calculations and observe RCR results

Practical use of ’Descriptors of use’ (DoU) • DoU is the main tool recommended in guidance for • the identification of use • and the headline in the ES • DoU is input parameter to exposure models • PROC => Occupational exposure calculation • PC/AC => Consumer exposure calculations • LCS+SU/PC/PROC/AC => ERC=>environmental exposure calculations • Conclusion from case studies in RIP 3.2 and various workshops: • DoU is difficult to use/not reproducible • More help is needed to find your way around in DoU
