Adding Fragrance to Cosmetics for Longevity

Yes, your understanding is generally correct. To help fragrance last longer in cosmetic formulations like creams, you can mix the fragrance oil with a fixative before adding the mixture to your cream base.

Here's a breakdown:

• Purpose of a Fixative: A fixative is used to reduce the evaporation rate of the fragrance, helping the scent linger for a longer time on the skin.
• Mixing Ratio: Mixing the fragrance and fixative in equal parts (1:1 ratio) is a common starting point. However, the optimal ratio can vary depending on the specific fragrance and the fixative you are using, as well as the desired intensity and longevity. You might need to experiment to find the best ratio for your particular fragrance.
• Adding to Formula: Once the fragrance and fixative are mixed, this blend is then incorporated into your cream formula during the appropriate phase (usually the cool-down phase).

As the staff mentioned, it's a good idea to test the fragrance on its own first. Some fragrances naturally have good longevity and may not require a fixative. Fixatives are particularly helpful for more volatile fragrance notes, such as fruity or citrus scents, which tend to evaporate quickly.

Products like Cassiffix, Fleuramone, and Violet Base are examples of fragrance components or bases that can be used in developing scents for cosmetic applications.
