Fixative for Ambroxan in Alcohol

Ambroxan is a base note ingredient known for its excellent longevity and fixative properties. When mixing Ambroxan with alcohol, Ambroxan itself acts as a natural fixative, helping the scent last longer.

While Ambroxan provides good longevity on its own, adding a dedicated fixative is common practice in perfumery, especially if you plan to add more volatile top or middle notes later. A separate fixative can help to 'anchor' the entire fragrance blend and improve overall performance and diffusion.

Regarding the amount of fixative:

The required amount of fixative depends heavily on the specific fixative material you choose and the desired strength and longevity of your final fragrance. There is no single percentage that fits all situations.

Common fixatives include various musk compounds, resins, or other synthetic materials. The typical usage level for a fixative in a fragrance concentrate (before dilution in alcohol) can range from 1% up to 5% or more, depending on its strength and purpose. Since you are currently only mixing Ambroxan and alcohol, if you add a fixative, the percentage would be relative to the amount of Ambroxan used, or the total weight of your final blend.

It is best to start with a small amount (e.g., 1-2% of the Ambroxan weight or total blend) and test the result, adjusting as needed.
