Which ingredients are making a formulation environmentally hazardous?First of all, a brief outline of how the hazard is calculated: The levels which trigger an environmental classification are 25% total contributors to the end point, e.g. 25% or more combined EH C1 components equals EH C1 on the formulation. When looking at EH C2 classification, it’s 25% contributing EH C2 which is the sum of EH C2 and 10 x EH C1. When looking at EH C3, this is the sum of EH C3 + 10 x EH C2 + 100 x EH C1 and so on. If something has an M factor then, this is taken into account also. These rules are in the legislation itself. In Formpak these rules are custom calculated properties, and you can see the code for them in the calculation tab of properties EH C1= and EH C2= and EH C3=. These properties are maintained by Formpak. If you want to see why a particular formulation has these (or other) hazards, then you can use Item Analysis Reports. Try ‘Print Item Analysis Report’ and choose ‘Report Type’ ‘GHS Hazard Contribution by Property Sources Report’ as a start – this will give you EH C1 and EH C2, plus all the other GHS hazard end points. This let’s you know which components are being added together to reach the end points and where they come from (e.g. inside essential oils or other complex items). This report can be a useful source of information if you are trying to reformulate to reduce hazards. You can access this report in other places (e.g. when adding a formulation, from view a raw material or formulation). Abbreviations: |
