Water-based Room Spray Formulation: Mixing Order and Dipropylene Glycol Percentage for Longevity

Asked by: jibimiho On: October 17, 2021 Product Type: Cosmetics

Question

I want to make a water-based room spray. The ingredients I have are Essential Oil, Water, and Flora Solve™ Clear. I also want to add Dipropylene glycol to make the scent last longer.

I would like to know the correct mixing order. Is it correct to mix Essential Oil with Flora Solve™ Clear first, then mix Water with Dipropylene glycol, and finally combine the two mixtures?

Also, what percentage of Dipropylene glycol should I add to the total formulation?

Answer

Yes, the mixing order you described is correct.

Here are the recommended steps for making your water-based room spray using your ingredients:

  1. In a first container, mix the Essential Oil with Flora Solve™ Clear. Stir well until the mixture is clear or well combined. (This step helps to solubilize or disperse the essential oil in the Flora Solve™ Clear).
  2. In a separate container, mix the Water with Dipropylene glycol. Stir until combined.
  3. Slowly pour the mixture from step 1 into the mixture from step 2 while stirring continuously until everything is well combined and clear.

Regarding the amount of Dipropylene glycol to help the scent last longer, you can add approximately 1-10% of the total weight of your formula. The exact percentage can be adjusted based on your preference and how long you want the scent to last. It's recommended to start with a smaller batch to test and adjust the ratio to achieve your desired result.
