Choosing Solubilizer for Clear Moisture Water
Question
I have a formulation with an oil phase consisting of Fractionated Coconut Oil and Lemongrass Oil, and a water phase consisting of clear liquid herbal extracts.
I want the final product to be a clear liquid similar to moisture water products like those from Muji. What type of emulsifier should I use?
Answer
Choosing an Emulsifier for Clear Moisture Water
To combine your oil phase (Fractionated Coconut Oil and Lemongrass Oil) with your water-based herbal extracts to create a clear liquid like a moisture water, you need a solubilizer. A solubilizer helps disperse the oil droplets very finely within the water phase, making the mixture appear clear instead of cloudy or separated.
A suitable solubilizer for this type of formulation is PEG-40 Hydrogenated Castor Oil.
How to Use:
- Mix the Fractionated Coconut Oil and Lemongrass Oil together.
- Add the PEG-40 Hydrogenated Castor Oil to the oil mixture and stir until fully combined. The ratio of solubilizer to oil will depend on the specific oils and the desired clarity, but a common starting point is a 1:1 or 2:1 ratio (solubilizer:oil). You may need to experiment to find the best ratio for your specific oils.
- Gradually add the oil/solubilizer mixture to your water-based herbal extracts while stirring continuously until a clear solution is achieved.
This method will help you achieve the clear, water-like texture you are looking for.
