Using Fixatives and Musk in Fragrance

When working with solid fixatives or musks, such as the product you referred to as "Last Fix" and Musk, it is generally necessary to dissolve them first before incorporating them into your fragrance formulation with alcohol.

• Dissolving and Cooling: Yes, you should dissolve the solid fixative/musk in a suitable solvent (like DPG - Dipropylene Glycol, or a small amount of the alcohol you will be using) by gently warming if needed. Once fully dissolved, it is crucial to let the solution cool down completely to room temperature before mixing it with the main quantity of alcohol and other fragrance components. Mixing a warm solution with alcohol can cause issues.

• Storing Dissolved Solution: You can typically dissolve a larger batch of the fixative/musk and store the resulting solution for future use. Store it in a tightly sealed, airtight container in a cool, dark place to maintain its quality and prevent evaporation.

Fixatives and musks are often considered base notes in perfumery and help to provide longevity and depth to the fragrance. They are usually blended with other fragrance components before adding the final amount of alcohol.
