Basic Water-in-Silicone Serum
Lotioncrafter Serum SE is a proprietary blend of self emulsifying silicone fluids designed to make the creation of water-in-silicone emulsions (or serums) simple. Along with Lotioncrafter Serum SE, serums are created and stabilized using a sodium chloride/sodium citrate buffer. This reduces interfacial tension and improves stability, as does the addition of glycerin and/or glycols (dipropylene, propylene or butylene glycol). These also contribute to increased preservative efficacy. This is a cold process emulsion; therefore if you have concerns about the quality of your water, heat and hold it at 180°F for 20 minutes and cool it to room temperature before proceeding. High shear (stick blender) mixing is not required; mixing with a stand mixer at moderate to high speed is preferred.

-
Combine Phase A ingredients in mixing vessel and set aside.
-
Combine all Phase B ingredients and stir to dissolve.
-
Using a stand or hand mixer on moderate to high speed, begin to add Phase B ingredients to the Phase A mixing vessel in a very slow stream or trickle (slow addition is critical). Once all of the water is incorporated, continue mixing 10-15 minutes until the emulsion is smooth and uniform. The final lengthy mixing will insure a smaller, uniform droplet size of the discontinuous water phase, improving long term stability.
Makes 300 grams (10 oz).
