Recommended Mixing Equipment and Speed for Cosmetics (Lotion, Cream, Hair Styling) in 3000cc Pitcher

Based on the discussion with the MySkinRecipes staff regarding your questions about equipment for making lotion and cream in batches of 2000-2500 CC using a 3000 CC stainless steel pitcher:

1. Heating Equipment (Melting Ingredients):

• Both an electric double boiler and an electric stove are suitable for heating and melting ingredients.
• The key factor is the ability to control the temperature accurately.
• Using a hot pot as a double boiler with an external digital temperature controller is also theoretically possible for the heating step.

2. Mixing/Emulsifying Equipment:

• For a batch size of 2-2.5 liters, a hand blender with the type of head you showed is not suitable. It does not generate enough "shear force" required to properly emulsify creams and lotions at this volume, which could lead to the product separating over time.
• The staff strongly recommends using a dissolver/disperser blade attached to an electric drill instead. This type of blade is designed to create the necessary shear force for effective mixing and emulsification, resulting in a smooth, stable product.

3. Recommended Dissolver/Disperser Blade Size:

• For your 3000 CC stainless steel pitcher (with a top diameter of 16cm and bottom diameter of 15cm), a dissolver/disperser blade size of 8-10 cm is recommended.

4. Recommended Electric Drill RPM for Mixing:

• When using a dissolver/disperser blade to mix creams, lotions, or hair styling products (wax/gel), an electric drill speed of approximately 700-800 RPM is sufficient to create adequate shear force for proper mixing and prevent separation.

In summary, while various heating methods can work if temperature is controlled, for mixing larger batches (2-2.5L), a dissolver/disperser blade on an electric drill (8-10cm blade, 700-800 RPM) is recommended over a standard hand blender to ensure proper emulsification and product stability.
