Car Air Freshener Formulation

To create a car air freshener, you typically combine a fragrance oil with a suitable base that helps diffuse the scent. A simple formula involves mixing fragrance oil with a solvent or carrier.

Basic Formula:

• Fragrance Oil: 20-30%
• Base/Solvent: 70-80%

Suggested Bases:

• Alcohol: Perfumer's alcohol or isopropyl alcohol can be used. Alcohol evaporates quickly, helping to release the fragrance.
• Dipropylene Glycol (DPG): DPG is a common carrier for fragrance oils in diffusers and air fresheners. It evaporates slower than alcohol, providing a longer-lasting scent.

Instructions:

1. Measure the desired amount of fragrance oil.
2. Measure the desired amount of your chosen base (Alcohol or DPG).
3. Combine the fragrance oil and base in a suitable container and mix gently until fully blended.
4. Pour the mixture into your car air freshener dispenser (e.g., a spray bottle, a diffuser bottle with reeds, or a hanging car diffuser).

Choosing a Fragrance Oil:

The choice of fragrance is entirely up to personal preference. You can use single fragrance oils or blend multiple oils to create a unique scent. Some examples of fragrance oils you might consider include Strawberry Fragrance Oil, Jasmine Fragrance Oil, Neroli Fragrance Oil, or Coffee Roaster (Fragrance Oil).

Start with the lower percentage of fragrance oil and adjust based on your desired scent strength.
