Fragrance Fixatives: Last Fix vs. Sugar Fix

Thank you for your question regarding fragrance fixatives for perfumes, specifically comparing Last Fix (also referred to as Flora Fix) and Sugar Fix.

Fragrance fixatives are ingredients used in perfumery to help reduce the evaporation rate of the more volatile fragrance components. This helps the scent last longer on the skin or in the application.

Based on our database search, specific product details for "Last Fix" and "Sugar Fix" were not found, so a direct comparison of their ease of use and longevity based on that information is not possible.

In general, the ease of use of a fixative can depend on factors like its solubility in the fragrance base (e.g., alcohol or oil) and its viscosity. Some fixatives are liquids that blend easily, while others might be more viscous or solid requiring warming or specific solvents.

The longevity provided by a fixative is related to its chemical structure, molecular weight, and vapor pressure. Compounds with higher molecular weights and lower vapor pressures tend to evaporate more slowly and can help anchor more volatile notes.

Regarding the use of Last Fix at 10%, this is a common starting point for many fragrance fixatives. However, the optimal percentage can vary significantly depending on the specific fixative used, the overall composition of your fragrance formula, and the desired intensity and wear time. It is generally recommended to start with a lower concentration (e.g., 1-5%) and gradually increase it while testing the fragrance to find the best balance without negatively impacting the scent profile.

Ultimately, the best way to determine which fixative is easier to use and provides better longevity for your specific fragrance creation is through experimentation with different fixatives and concentrations.
