Add Raw Material Composition
Compositions can be useful for complex raw materials such as essential oils, for purchased mixtures and bases and for multi-constituent chemicals.
Raw materials include this extra layer of composition information when required to manage regulatory and technical matters. For example to give accurate information about GHS, IFRA and Allergens.
Raw Materials with compositions can be used just like other raw materials in formulations. When regulatory information is being determined for calculations or documents this will often involve looking ‘inside’ the raw materials to see the key drivers of hazards and properties, and components which may need to be reported.
To Add a Composition to a Raw Material
Select the Raw Material of interest using Instant Search, then press Add Composition button. You are taken to the Raw Material version of the CDT to add the composition information. Add components and concentrations. When finished, select the ‘Save & Check In’ button. There will be a prompt regarding Preserve when Exploding, which typically will be the default of No. For more information see article Preserve when exploding on raw material composition.
When Save & Check in is complete, the first version of the Raw Material Composition is created. The Composition tabs of View and Modify a Raw Material will contain information, and the View Composition and Print Composition buttons will be available for selection.
Raw Material Composition Total
Raw Material compositions work differently to formulation composition in that the concentrations of all components added are treated as percentages. This means the ‘formula’ does not need to add up to 100, it can be below or above 100 – all components will be treated as a percentage based on the actual concentration added.

For more information about the CDT see the Composition Design Tool Overview.
- How do I know what to enter for the composition of my complex raw material?
The information you use for the raw material composition should relate to the material you buy and use. If you are buying a commercial mixture, such as a perfume, flavour or a base, then the relevant composition is required to be communicated to you via the Safety Data Sheet from your supplier, typically in section 3. You may require additional information, e.g. about allergens or limited ingredients, which should be available from your supplier.
Industry data such as the IFRA IOFI Labelling Manual may contain composition information about essential oils.
- I have a raw material which is showing as ‘Checked Out’, what does this mean?
Adding or modifying a raw material composition is considered to be a one step process. That is, the User adds the raw material composition and then uses Save & Check In to finish the process. If a User is interrupted in the process or inadvertently does not press Save & Check in before exiting, the Raw Material remains in a ‘Checked Out’ state, which makes it unavailable for editing. In this case, the Raw Material needs to be returned to a normal state before progress can be continued. For more information see ‘Undo Pending Changes to Composition of Raw Materials’.
- How do I delete a raw material composition?
You can completely remove the composition of a raw material by using ‘Remove Raw Material Composition’. This is irreversible but the original composition can be viewed using ‘View Previous Versions of a Composition’.
