Creating a Body Oil that Turns Milky on Skin
Question
I want to make a body oil that turns milky when applied to the skin and is left on without rinsing. Which ingredient should I use to achieve this milky effect?
Answer
Creating a Milky Body Oil
To create a body oil that turns milky when applied to the skin and left on without rinsing, you need to incorporate an emulsifier into your oil blend. This type of product is often called a self-emulsifying body oil or cleansing oil (though in this case, it's left on).
The emulsifier allows the oil phase to mix with the water present on the skin surface, forming a temporary emulsion that appears milky.
We recommend using Emulsifying Wax 1000 for this purpose. It is an O/W (Oil-in-Water) emulsifier that helps oil and water combine effectively. When your oil blend containing Emulsifying Wax 1000 comes into contact with the moisture on your skin, it will emulsify, creating that desired milky texture.
How to use:
- Mix Emulsifying Wax 1000 into your oil phase.
- Heat the oil phase to melt the wax and ensure it is fully dispersed.
- A typical usage rate for Emulsifying Wax 1000 is 1-5% of the total formula, depending on the desired effect and oil content.
By adding Emulsifying Wax 1000 to your chosen blend of oils, you can achieve the milky transformation effect when applied to the skin.

Regarding a Body Oil formulation that contains both water and oil, the user wants to know:
- Will the resulting product be cloudy or clear?
- Is it possible to create a clear Body Oil formula that contains both water and oil?
- They are requesting recommendations on how to achieve a clear formula.
Answer:
Clear vs. Cloudy Oil-Water Mixtures
When you mix oil and water together, they naturally separate because oil is not soluble in water. To get them to stay mixed, you need to create an emulsion, usually by using an emulsifier and applying energy (like stirring or blending).
A standard emulsion of oil and water, like a lotion or cream, appears cloudy or opaque. This is because the oil droplets are dispersed in the water (or vice versa), and these droplets are large enough to scatter light, making the mixture look milky or white.
To achieve a clear mixture of oil and water, you typically need to create what's called a microemulsion. This requires a special type of ingredient, often called a solubilizer, which can disperse the oil into extremely tiny droplets (micelles) that are too small to scatter visible light.
For your body oil formula that contains both water and oil, if you use a standard emulsifier (like the Emulsifying Wax 1000 mentioned previously, which is designed to create a milky effect on skin contact), the product itself will likely be a cloudy or milky emulsion if it contains a significant water phase mixed in.
If you want the final product (the mixture of water and oil in the bottle) to be clear, you would need to use a solubilizer. Solubilizers are generally used to dissolve small amounts of oil (such as fragrances, essential oils, or certain active ingredients) into a water base to create a clear solution. They are not typically used to make large amounts of oil clear within a water base, as this would require a very high percentage of the solubilizer, which might affect the texture and feel.
Based on your goal of a body oil, using a solubilizer to make a large oil phase clear within a water phase might not be the most practical approach for a leave-on product, as the primary component is usually oil. However, if you are adding a small water-soluble component or fragrance/essential oil to an oil base and want it clear, a solubilizer could help.
We offer solubilizers that can help achieve clarity when dissolving oils in water:
- Flora Solve™ Clear: This is a fragrance solubilizer that helps combine essential oils and fragrance oils with water or water gel to create clear, stable microemulsions. It is colorless and odorless.
- Free Solve™ (PEG-Free Solubilizer): This is a high-performance, non-ionic, PEG-free solubilizer that can dissolve oils, perfumes, and essential oils in water, resulting in clarity.
Using these solubilizers allows you to incorporate small amounts of oil into a water-based formula (or vice versa, depending on the specific solubilizer and ratio) while maintaining clarity, unlike standard emulsifiers which result in cloudy emulsions.
