Comparing Fractionated Coconut Oil and Dipropylene Glycol as Fragrance Bases

Subject: Comparing Fractionated Coconut Oil and Dipropylene Glycol as Fragrance Bases

Regarding your question about using Fractionated Coconut Oil and Dipropylene Glycol (DPG) as fragrance bases instead of alcohol, and which one helps with longevity:

Based on the information provided, Dipropylene Glycol (DPG) is not suitable for use as a fragrance base. While DPG can be used in small amounts as a fixative to help slow down the evaporation of fragrance components and improve longevity, using it as the primary base will significantly hinder the diffusion (sillage) of the fragrance. This means the scent will not project well.

Fractionated Coconut Oil, on the other hand, can be used as an oil-based fragrance base. Oil-based perfumes typically sit closer to the skin and have less sillage compared to alcohol-based perfumes. However, the oil can help the fragrance last longer on the skin by slowing down the evaporation rate of the fragrance oils.

Comparison as a Base:

• Fractionated Coconut Oil:
  • Pros: Can be used as an alternative base for oil-based perfumes (e.g., rollerballs), can help longevity on the skin, provides a different skin feel.
  • Cons: Significantly reduces fragrance diffusion (sillage) compared to alcohol, results in a more intimate scent.
• Dipropylene Glycol (DPG):
  • Pros: Useful as a fixative in small amounts to improve longevity and stability of fragrance components.
  • Cons: Not suitable as a base because it hinders fragrance diffusion.

Conclusion:

Between the two, Fractionated Coconut Oil is the viable option if you want to create an oil-based fragrance base. DPG is not appropriate as a base; its role is primarily as a fixative or diluent in small quantities within a formulation, often alongside alcohol or other solvents, to help with longevity and solubility, but not as the main base itself.

For better diffusion and projection similar to traditional spray perfumes, alcohol is typically used as the base. If you prefer an oil-based fragrance with less sillage but potentially good skin longevity, Fractionated Coconut Oil is a suitable carrier.
