Using Alternative Equipment for Water-in-Oil Emulsions

Regarding your question about using a magnetic stirrer, hand blender, or fruit blender for making Water-in-Oil creams, especially for small batches around 100g:

• Magnetic Stirrer: As discussed, a magnetic stirrer is generally not suitable for creating stable Water-in-Oil emulsions. These emulsions require significant shear force to properly mix the water and oil phases, and a magnetic stirrer typically does not provide enough shear.

• Hand Blender or Fruit Blender: These tools can potentially be used as they provide shear. However, their effectiveness for a 100g batch will depend on the specific model's power and design. A standard fruit blender jug might be too large for such a small volume to achieve proper mixing and shear. A hand blender, which can be placed directly into a smaller container, might be more effective for small batches, provided it generates sufficient shear.

As the staff suggested, the best approach is to experiment with your specific hand blender or fruit blender to see if it can successfully create a stable emulsion with your chosen Water-in-Oil formula at the 100g scale.

When making Water-in-Oil emulsions using emulsifiers like Water-in-Oil EZ™, Water-in-Oil Max™, or Water-in-Oil Balance™, the general mixing method involves adding the water phase gradually to the oil phase while continuously blending or stirring vigorously. Achieving a stable emulsion relies heavily on this continuous mixing and sufficient shear during the addition of the water phase.

While dedicated cosmetic blenders are designed for optimal emulsion creation across various batch sizes, it is possible that a powerful hand blender could work for small personal-use batches if it provides adequate shear.
