The different types of compositions encountered in EHS include, Standard Composition, Exact Composition Based on Products (ECbP), Exact Components based on Components / Starting Material, Hazardous Composition, Legal Composition, REACH Use and Exposure Composition (U&E Comp), Impurities, Hazardous Ingredients (EU), DPDPlus and Pure Composition. Besides above standard types, based on client requirement there might be other flavours too. Here's the short overview of each of the component type.
1) Exact Components based on Products – Substances that are actually contained in the product after the production process has been completed and that can be detected by analysis. Can also consist of products which in turn consist of other components. This component type is generally used by different Expert Rules to calculated secondary data.
2) Standard Composition – Ingredients are substances, that are actually contained in the product after the production process has been completed and that can be detected by analysis. These are generally taken from ECbP composition type and added together. These are calculated by Expert Rules – EHS Standard Comp Rule set.
3) Hazardous Ingredients - On the Composition tab page, specify the contents of the corresponding ingredients with lower limit, upper limit, and average value. In addition, specify the unit for the selected reference value.
4) Components with Occupational Exposure Limits - List of ingredients or ingredient groups (and their quantities) that are subject to an atmospheric limit value and must be specified with this limit value in the EU Safety Data Sheet in the current version), or in accordance with the Technical Regulations for Hazardous Substances.
5) Legal Composition – It’s an optional composition type excluding all impurities from Standard Composition for meeting legal requirements lik REACh. This together with recent release of Impurties –ideally should equal to Standard Composition.
6) REACH Use and Exposure Composition – Contains all substance, which are relevant for supply chain communication. Substances which are used in Compliance Workbench for triggering Supply chain communication.
