Mixing Oil Soap with Cooking Oils and the Need for Oil Blender

Yes, you can mix MIPA Laureth Sulfate Oil Soap (Oil Soap) with common cooking oils like coconut oil or soybean oil. Oil Soap is a surfactant designed to emulsify oils, allowing them to be rinsed off with water. This is the basis for creating rinseable cleansing oils.

Regarding Oil Blender, if you are making a rinseable cleansing oil using Oil Soap and oils, you do not need Oil Blender. Oil Soap's role is to emulsify the oil with water when you rinse, not to prevent separation between the Oil Soap and the oil itself (they mix well). Oil Blender is typically used for creating stable emulsions of oil and water in formulations like creams or lotions, which is a different application than a simple rinseable cleansing oil. The fact that the Oil Soap and oil don't separate is expected and doesn't mean you need Oil Blender; it just means they are miscible.
