Alcohol-Free Long-Lasting Pheromone Perfume Formulation

Okay, I can help analyze this formula and propose an alternative that aims to be alcohol-free while maintaining longevity.

Based on the discussion, the user wants a long-lasting pheromone perfume without alcohol.

Here's a breakdown of the original formula components and the challenges:

1. Dehydroepiandrosterone Sulfate (DHEAS) (0.2% in Alcohol): This is the pheromone component. The product itself is a 0.2% solution in Alcohol. This means the raw material already contains alcohol. Using this specific product makes a completely alcohol-free final product technically impossible, as 30% of the formula will introduce alcohol from this ingredient (30% * 0.2% = 0.06% DHEAS, and 29.94% Alcohol).
2. Last Fix™: This is for longevity. The staff mentioned it needs to be dissolved in Alcohol with heating and cannot dissolve in Dipropylene Glycol (DPG). This is another challenge for an alcohol-free formula.
3. Dipropylene Glycol (DPG): A common solvent and carrier. The staff noted that a high percentage (like the initial 30%) can make spraying difficult.
4. Perfume: The fragrance concentrate.

The goal is to replace the bulk Ethyl Alcohol used as a carrier with an alcohol-free alternative like Reed Diffuser Base (Type 1) and manage the DPG level for sprayability, while incorporating DHEAS and Last Fix™.

Achieving a completely alcohol-free product with the specified DHEAS ingredient and the staff's instructions for Last Fix™ dissolution (requiring alcohol) is difficult. However, we can create a formula that avoids adding bulk alcohol and uses alcohol-free carriers for the main base.

Here is a proposed formula using Reed Diffuser Base (Type 1) and DPG as the alcohol-free carrier base, aiming for longevity and sprayability:

Proposed Alcohol-Free Base Formula:

• Dehydroepiandrosterone Sulfate (DHEAS) (0.2% in Alcohol) - 30%
• Last Fix™ - 10%
• Perfume - 30%
• Dipropylene Glycol (DPG) - 10%
• Reed Diffuser Base (Type 1) - 20%
• Total: 100%

Explanation of Components:

• Dehydroepiandrosterone Sulfate (DHEAS) (0.2% in Alcohol): Provides the pheromone effect. Please note that this raw material contains alcohol as its solvent.
• Last Fix™: Helps to extend the longevity of the fragrance.
• Perfume: Your chosen fragrance concentrate.
• Dipropylene Glycol (DPG): Acts as a solvent and carrier. Keeping it at 10% helps with solubility and sprayability compared to a higher percentage.
• Reed Diffuser Base (Type 1): This acts as the primary alcohol-free carrier and helps to diffuse the scent. The staff confirmed it has a very weak odor and does not significantly alter the perfume scent.

Mixing Instructions:

1. According to staff instructions, Last Fix™ needs to be dissolved. While staff recommended alcohol + heating, you are aiming for alcohol-free. You could try gently heating the Reed Diffuser Base (Type 1) and Last Fix™ together (around 60°C) and stirring until Last Fix™ is completely dissolved.
2. Let the mixture cool down.
3. Once cooled, add the Dehydroepiandrosterone Sulfate (DHEAS) (0.2% in Alcohol) and your Perfume concentrate.
4. Stir gently until all components are thoroughly combined.

Important Considerations:

• This formula avoids adding bulk Ethyl Alcohol, but the DHEAS raw material itself contains alcohol.
• The dissolution of Last Fix™ without alcohol might be challenging. If dissolving Last Fix™ in Reed Diffuser Base with heating is unsuccessful, you might need to follow the staff's original advice of dissolving it in a minimal amount of alcohol first, which would introduce more alcohol into the final product.
• The combination of DPG and Reed Diffuser Base is intended to provide a sprayable, alcohol-free base. You may need to test sprayability and adjust the ratio of DPG to Reed Diffuser Base slightly if needed.

This formula provides an alcohol-free base solution while incorporating the desired active ingredients for a long-lasting pheromone perfume.
