Perfume Formulation for Skin: Enhancing Longevity and Diffusion with Last-Fix

Okay, I understand you're asking for a perfume formulation for skin application that offers good scent diffusion and longevity, based on the previous staff suggestion.

Based on the information provided, the recommended approach involves using a fixative like Last-Fix and mixing it with perfume concentrate and alcohol.

Here is the example formula provided:

• Perfume Concentrate (หัวน้ำหอม): 30%
• Last-Fix: 10%
• Ethyl Alcohol (99.9%, Perfumer's Grade): 60%

Explanation of the components:

• Perfume Concentrate: This is the core fragrance component that provides the desired scent. A 30% concentration is relatively high, which contributes to a stronger and potentially longer-lasting fragrance.
• Last-Fix: This ingredient acts as a fixative. Its purpose is to help "anchor" the fragrance molecules, slowing down their evaporation and making the scent last longer on the skin. It also helps improve scent diffusion.
• Ethyl Alcohol: This is the primary solvent in most skin perfumes. It dissolves the fragrance and fixative, allows the mixture to be sprayed, and evaporates quickly upon application, helping to project the scent (diffusion). Using a high-purity, perfumer's grade alcohol is important to avoid unwanted odors.

This formula provides a good starting point for creating a skin perfume with enhanced diffusion and longevity, specifically incorporating the suggested Last-Fix product.
