Perfume Spray Formulation for Sensitive Skin (Alcohol-Based)

Here is a simple alcohol-based perfume spray formulation based on your requirements and the previous discussion, suitable for sensitive skin and designed for longevity:

Recommended Formula

• Perfume (Fragrance Oil): 20%
• Last Fix™: 10%
• Ethyl Alcohol (Perfumer's Grade): 70%

This formulation uses Ethyl Alcohol as the primary solvent, which is standard for alcohol-based perfumes and helps the fragrance diffuse and evaporate properly. The staff's recommendation to use only Ethyl Alcohol and no water is correct for this type of spray.

Ingredient Roles

• Perfume (Fragrance Oil): Provides the desired scent.
• Last Fix™: Acts as a fixative to help the fragrance last longer on the skin.
• Ethyl Alcohol: Dissolves the fragrance and fixative, allowing it to be sprayed and evaporate, leaving the scent behind. Using a high-purity, low-odor perfumer's grade Ethyl Alcohol is recommended for the best scent quality and reduced potential irritation compared to lower grades.

Mixing Instructions

1. In a clean container, combine the Perfume (Fragrance Oil) and Last Fix™. Stir or gently swirl to mix them together.
2. Gradually add the Ethyl Alcohol to the mixture while stirring gently until everything is clear and well combined.
3. Pour the mixture into a spray bottle.

Allow the perfume to macerate (sit) for a period (usually a few weeks in a cool, dark place) to allow the fragrance components to meld and strengthen, although for simple formulas, it can often be used sooner.

Regarding Your Questions

• Mixing with Water: As confirmed by the staff, water is generally not used in this type of alcohol-based perfume spray. Alcohol is the solvent for the fragrance. Adding water can cause the mixture to become cloudy or unstable, especially with higher fragrance concentrations.
• Using Ethyl Alcohol Alone: Yes, Ethyl Alcohol is the correct primary solvent for this alcohol-based spray formulation.
• Flora Solve: Flora Solve is a solubilizer designed to mix fragrance oils with water or water gels without the use of alcohol. Since this formula is alcohol-based, Flora Solve is not needed.

Sensitive Skin Considerations

While this formula uses common perfume ingredients, both fragrance oils and alcohol can potentially cause irritation for sensitive skin. Using a high-quality, low-odor perfumer's grade Ethyl Alcohol (such as 96% or 99.9%) is preferable. Always perform a patch test on a small area of skin before applying the perfume liberally.
