Perfume Spray Formulation Questions

Here are answers to your questions regarding your perfume spray formulation:

1. Using Flora Fix and Last Fix Together

Based on the information, using both Flora Fix and Last Fix together in your body spray formula is not necessary. Last Fix is generally more effective for improving fragrance longevity than Flora Fix. Using both will not significantly improve the result compared to using Last Fix alone.

2. Skin Irritation

The burning sensation and redness you experienced after spraying the perfume on your skin are likely due to the Tea Tree Oil in your formula, not the alcohol concentration. Tea Tree Oil, especially at the concentration you used (5% in the fragrance oil blend, which is 1.5% in the final spray), can be highly irritating to the skin. The recommended usage rate for Tea Tree Oil on body skin is 0.1-1%, and not more than 0.5% for facial skin.

3. Fragrance Blending and Scent Strength

It is common to find that the intensity of different fragrance components varies greatly. Even if you use a higher percentage of one component like Fresh Melon, a stronger scent like Tea Tree Oil can easily overpower it, even at a lower concentration. Perfume blending is indeed complex and requires practice and testing to understand how different chemicals interact and balance each other. Studying fragrance chemistry can be helpful.

4. Tea Tree Oil for Wounds

While Tea Tree Oil does possess antiseptic properties, it is strongly advised not to use it on fresh or healing wounds, such as ear piercing sites. Tea Tree Oil can cause significant skin irritation, and this irritation is much more severe on damaged or healing skin. Using it on a wound could impede the healing process and cause further discomfort or adverse reactions.

5. Longevity of Powdered Fragrance Components

Yes, generally, fragrance components that are in powder form tend to have slower evaporation rates compared to liquids. This slower evaporation means their scent will last longer on the skin, although the initial intensity might be weaker than more volatile liquid components.
