Rosemary Oleoresin Extract (ROE) Sold:

Listing Solvents in INCI Name:

According to the general principles of the INCI (International Nomenclature of Cosmetic Ingredients) system, if an extract contains a solvent or diluent, both the extract and the solvent/diluent should be listed in the INCI name to indicate the full composition of the ingredient.

However, for the specific product Rosemary Oleoresin Extract (ROE) (Product ID 167), the listed INCI name is Rosmarinus Officinalis (Rosemary) Leaf Extract, which only specifies the rosemary extract component and does not mention the natural extracted oil it is mixed with.

Therefore, while the principle is to list all components, in practice, the INCI name shown on the raw material label may vary depending on interpretation and registration. However, generally, if a primary solvent used in the extraction or a significant diluent is present, it should be indicated in the Technical Data Sheet or Safety Data Sheet of the raw material for clarity.
