Adjusting Reed Diffuser Formula for Better Scent Diffusion and Longevity
Question
How should I adjust my reed diffuser formula, which currently uses fragrance oil, 99% Ethyl Alcohol, and a specific diffuser base, to improve scent diffusion and reduce rapid evaporation? Should I modify the proportions, add substances like DPG, or switch to 95% Ethyl Alcohol?
Answer
Recommendations for Improving Your Reed Diffuser Formula
Based on your current formula (30ml fragrance oil + 55ml Ethyl Alcohol 99% + 15ml diffuser base1), the issues with poor scent diffusion and rapid evaporation are likely due to the high proportion of 99% Ethyl Alcohol.
Ethyl Alcohol, especially at high concentrations, evaporates very quickly. This causes the liquid level in the bottle to drop rapidly and the scent diffusion to be inconsistent over time. While alcohol helps with initial scent throw, a large amount leads to the scent fading quickly.
The Reed Diffuser Base (Type 1) you are using is specifically designed to address these problems. According to the product information, this base does not contain DPG, Propylene Glycol, or any type of alcohol. It helps dissolve fragrance oil and promotes good scent diffusion without leaving stains.
The recommendation is to adjust the proportions by significantly reducing or eliminating the Ethyl Alcohol and increasing the proportion of the Reed Diffuser Base (Type 1) instead.
According to the usage instructions for Reed Diffuser Base (Type 1), the appropriate ratio is:
- Reed Diffuser Base (Type 1): Approximately 70-75%
- Fragrance Oil: Approximately 25-30%
Try starting with proportions around this range, for example, mixing 25 ml of fragrance oil with 75 ml of Reed Diffuser Base (Type 1) (for a total volume of 100 ml), or adjust based on the total volume you wish to make.
Using a dedicated reed diffuser base in a higher proportion will help to:
- Slow down evaporation: The liquid will last longer.
- Ensure consistent scent diffusion: The base helps carry the fragrance steadily up the reeds, allowing the scent to spread well throughout the room.
Regarding DPG (Dipropylene Glycol), it is another substance commonly used as a base in reed diffusers because it also evaporates slowly. However, since the Reed Diffuser Base (Type 1) you are using is stated to be DPG-free, adding DPG to this specific base may not be necessary. If you wish to use DPG as the primary base instead of the Reed Diffuser Base, you can do so in similar proportions (e.g., 25-30% fragrance oil mixed with 70-75% DPG). However, it is recommended to first try adjusting your formula using the Reed Diffuser Base (Type 1) you have according to the recommended proportions.
