Subject: Mixing Soy Lecithin with Water, Oil, and Actives
Based on the information for Soy Lecithin (Product ID 256), the basic mixing method is as follows:
- Dissolve the Soy Lecithin in the oil phase.
- Heat the oil phase (containing the dissolved lecithin) to 80°C.
- Separately, heat the water phase to a similar temperature (around 80°C).
- Combine the heated oil phase and water phase, and mix thoroughly to form an emulsion.
Regarding the addition of active ingredients:
- Many active ingredients, especially those sensitive to heat, should be added during the cool-down phase after the emulsion has been formed and has started to cool.
- Once the emulsion has cooled sufficiently (e.g., below 40°C or as recommended for the specific active), add the active ingredients and mix well until evenly dispersed.
- Some heat-stable active ingredients might be added to their respective phases (oil or water) before heating and emulsification, but this depends entirely on the specific active ingredient's properties and recommended usage.
Always refer to the specific instructions for each active ingredient you are using.
