Hanging Car Air Freshener Formula

To make a hanging car air freshener with good diffusion and scent, you will need a fragrance oil and a suitable base liquid. Dipropylene Glycol (DPG) is commonly used as a base for this type of air freshener because it helps to dissolve the fragrance oil and allows for gradual diffusion into the air.

A simple formula ratio you can start with is:

• Fragrance Oil: 30-50%
• Dipropylene Glycol (DPG): 50-70%

You can adjust the ratio based on the strength of your fragrance oil and desired intensity.

Instructions:

1. Carefully mix the fragrance oil and DPG in a container.
2. Prepare your absorbent material (e.g., felt pad, cardboard shape).
3. Soak the absorbent material in the mixture until fully saturated.
4. Allow any excess liquid to drip off, then hang the air freshener in your car.

Choose a fragrance oil you like, such as Jasmine Fragrance Oil or Neroli Fragrance Oil, to create your desired scent.
