Emulsifier for lightweight herbal water/oil essence or toner

For a formulation with a higher proportion of herbal water than oil, aiming for a very lightweight texture similar to a Water Gel Essence or a slightly viscous toner, an Oil-in-Water (O/W) emulsifier specifically designed for light textures is recommended.

Based on the search results, Light Lotion Maker is a very interesting option that best matches your requirements.

• Light Lotion Maker is a high-performance emulsifier that effectively binds oil and water and provides a very light, non-sticky texture. It can be used in formulas with a high water phase (it can emulsify up to 40% oil, meaning the water phase can be 60% or more).
• It can be used in a Cold Process, which is convenient for formulations containing heat-sensitive herbal ingredients.
• If you desire a slightly more viscous texture (like a slightly thick toner), you might consider using Light Lotion Maker along with a small amount of a water-phase thickener like Xanthan Gum. This can help adjust the texture and prevent separation.

Using the appropriate emulsifier will help you achieve the desired lightweight and stable texture.
