DIY Body Perfume Formulation: Achieving Longevity, Diffusion, and UV Stability
Question
I have received concentrated fragrance oil from a friend and wish to formulate a DIY body perfume for personal use. I have already purchased some ingredients from My Skin Recipes.
Could you please recommend the necessary ingredients and formulation guidelines to achieve a perfume that meets the following criteria?
- Longevity: Must be long-lasting on the skin.
- Diffusion: Must be diffusive (sillage) and not heavy or thick (non-heavy/non-oily texture).
- Packaging Stability: Must be suitable for packaging in clear bottles while remaining resistant to sun/light degradation.
Answer
Based on your requirements for a long-lasting, diffusive, non-heavy perfume suitable for clear, light-resistant bottles, the best approach is to use a high-quality alcohol base combined with a dedicated fixative and a UV absorber.
Here are the recommended ingredients from My Skin Recipes:
1. Solvent/Base (For Diffusion and Non-Heavy Feel)
- Product: Ethyl Alcohol (96% , Perfumer Grade, Low-Odor) (ID: 35354)
- Benefit: Alcohol is the standard solvent for fine fragrance. It provides the best diffusion (sillage) and a non-heavy, non-oily feel on the skin. The low-odor grade ensures it won't interfere with your concentrated fragrance oil.
2. Fixative (For Longevity)
- Product: 12H Fix™ (Fragrance Fixative) (ID: 7835)
- Benefit: This specialized fixative helps to slow down the evaporation rate of the fragrance molecules, significantly increasing the longevity (ติดทนนาน) of the scent on the skin.
3. UV Protection (For Clear Bottles)
- Product: UV Absorber 531L (ID: 245067)
- Benefit: When using clear bottles, a UV absorber is essential to prevent sunlight from degrading the fragrance oil and changing its color or scent over time. This product helps maintain the stability of your perfume.
General Formulation Guideline (Eau de Parfum Concentration)
A typical Eau de Parfum (EDP) concentration is 15-20% fragrance oil. You can adjust this based on the strength of your concentrated oil.
| Component | Recommended Percentage | Purpose |
|---|---|---|
| Concentrated Fragrance Oil | 15% - 25% | Scent |
| 12H Fix™ (ID: 7835) | 1% - 5% | Longevity |
| UV Absorber 531L (ID: 245067) | 0.05% - 0.2% | Light Protection |
| Ethyl Alcohol 96% (ID: 35354) | Balance (e.g., 70% - 84%) | Solvent, Diffusion |
Mixing Instructions:
- Combine the Concentrated Fragrance Oil, 12H Fix™, and UV Absorber 531L in a glass container. Mix well.
- Slowly add the Ethyl Alcohol 96% while stirring gently.
- Seal the mixture tightly and allow it to macerate (aging) in a cool, dark place for at least 2-4 weeks. This process is crucial for the ingredients to fully blend and for the scent to mature and become truly long-lasting and well-rounded.
