Oil-Based Perfume Roll-On Formulation

Regarding your questions about creating an oil-based perfume roll-on using Fractionated Coconut Oil, essential oils, and fragrance oils:

1. Do you need Dipropylene glycol to dissolve the fragrances?
   You do not strictly need Dipropylene glycol (Dipropylene glycol) solely for dissolving essential oils and fragrance oils in Fractionated Coconut Oil (Fractionated Coconut Oil). Fractionated Coconut Oil is an excellent carrier oil that is suitable for blending with both types of fragrances and can dissolve them effectively in an oil-based system like your roll-on.
   Dipropylene glycol is a solvent and fixative often used in perfumes, but it is miscible with water. While it can help dissolve fragrances and extend scent longevity, its properties might make purely oil-soluble fixatives or carriers more suitable for a purely oil-based product like a roll-on using Fractionated Coconut Oil.

2. Can Sugar Fix™ be used for longevity, or is there a better alternative?
   Based on the available information from our product search, we do not have specific details regarding the suitability or performance of a product named "Sugar Fix™" as a fixative for oil-based perfumes. Therefore, we cannot confirm if it is suitable for your application.
   As mentioned earlier, Dipropylene glycol is known to act as a fixative and can help perfume last longer. However, for a purely oil-based system like yours, you might find oil-soluble fixatives or ingredients that slow down evaporation more effective or easier to incorporate than water-miscible options like Dipropylene glycol.

For your oil-based roll-on using Fractionated Coconut Oil, the oil itself acts as the primary carrier and will help the scent adhere to the skin. The longevity will depend on the volatility of the specific essential oils and fragrance oils you use. Base notes tend to last longer than top or middle notes.
