Adding Oil-Soluble Fragrance to Water-Based Gel without Alcohol/Oil
Question
I have a water-based gel formulation for face care that does not contain any oil or alcohol. I would like to add an oil-soluble fragrance, such as a rose fragrance oil, to this gel. How can I effectively incorporate this oil-soluble fragrance into the water-based gel to achieve a light scent without affecting the clarity or stability of the gel?
Answer
Incorporating Oil-Soluble Fragrance into Water-Based Gel
To add an oil-soluble fragrance, such as a rose fragrance oil, into a water-based gel formulation that contains no oils or alcohol, you can use a solubilizer like Polysorbate 20.
Here's how you can do it:
- Mix the fragrance oil with Polysorbate 20 separately before adding it to your gel base.
- A recommended starting ratio is approximately 5 parts Polysorbate 20 to 1 part fragrance oil (5:1 ratio). You may need to adjust this ratio depending on the specific fragrance oil to achieve clarity and stability in your gel.
- Mix the fragrance and Polysorbate 20 thoroughly until the fragrance is fully dispersed in the Polysorbate 20.
- Slowly add this mixture to your water-based gel formulation while stirring.
Polysorbate 20 is soluble in water and can help disperse the oil-soluble fragrance evenly throughout the water phase, preventing turbidity or separation. The typical usage rate for Polysorbate 20 in formulations is between 1% and 20%, but the exact amount needed will depend on the amount of fragrance used and the desired clarity.
By using Polysorbate 20 in this manner, you can successfully incorporate a small amount of oil-soluble fragrance to provide a light scent to your water-based gel.
