Water-in-Oil Serum Formulation with Water-in-Oil EZ™: Sample Formula & Mixing Guide

Question

Could you please provide a sample formula and mixing instructions for creating a Water-in-Oil serum using Water-in-Oil EZ™? I would also like to understand potential issues like separation and how mixing equipment affects the process.

Based on the provided information, a sample formula includes:

Water-in-Oil EZ™ 1%
LipidSoft Lite 10%
Water 89%

The mixing steps involve combining the oil phase (Water-in-Oil EZ™ + LipidSoft Lite), then slowly adding the water phase while continuously stirring or blending. A video demonstration was provided showing the use of a Magnetic Stirrer at 1000 RPM.

What are the key considerations for successful emulsification, especially regarding mixing power and the percentage of Water-in-Oil EZ™ needed based on oil/silicone content? What might cause separation?

Based on the discussion: Magnetic Stirrer: A Magnetic Stirrer can be used for small quantities, and the staff uses one (at 1000 RPM) in their examples. However, some users reported issues with insufficient power or separation. The key is to add the water phase slowly while continuously stirring. Water-in-Oil EZ™ Percentage: The amount needed depends on the oil and silicone content. More oil/silicone requires more emulsifier, but increasing these components can make the formula less viscous. Thickening: To thicken the formula, use thickeners like Xanthan Gum (water phase) or Cetyl Alcohol (oil phase, requires heat). Mixing Method: Mix the oil phase components, then slowly add the water phase while continuously stirring. A video tutorial was provided by the staff demonstrating this process with an example formula (Water-in-Oil EZ™ 1%, LipidSoft Lite 10%, Water 89%). If you are experiencing separation, it suggests the emulsion did not form correctly, potentially due to insufficient mixing power or speed during the water addition phase, or issues with the formula composition.
