Adding Surfactants to Natural Liquid Soap

Regarding adding PEG-7 Glyceryl Cocoate (Coco Wash) and MIPA Laureth Sulfate (Oil Soap) to a natural liquid soap made from oils and lye:

If your liquid soap is already produced through the saponification of oils and lye, the soap itself acts as the primary cleansing agent (surfactant). Adding additional surfactants like PEG-7 Glyceryl Cocoate or MIPA Laureth Sulfate is generally not necessary for the soap's function.

If you still wish to incorporate them, the correct step for adding them depends heavily on your specific soap formulation and process. Without knowing the full formula, it is difficult to provide precise instructions.

Regarding adding them at the same time as essential oils: Essential oils are typically added during the cooling phase or at the very end of the formulation process, after the main base is complete and has cooled down sufficiently. Surfactants are usually incorporated earlier, often into the water phase or the main soap base, sometimes requiring specific temperatures or mixing conditions to dissolve or disperse properly. Adding surfactants and essential oils simultaneously is not the standard procedure and might affect the final product's stability or appearance.

In summary, adding these surfactants is likely not needed in a saponified soap. If you choose to add them, the timing depends on your specific formula, and adding them at the same time as essential oils is generally not recommended.
