Formulation Mixing Procedures

Here are the answers regarding the correct mixing procedures for cosmetic formulations:

1. Mixing Water and Oil Phases: The method for mixing the water phase and the oil phase depends on the type of emulsifier or cream maker used. Some emulsifiers are added to the oil phase, while others are added to the water phase, or even during the emulsification process. It is crucial to check the specific instructions for the emulsifier you are using. For example:

   • Emulsifying Wax 1000 and Sucrose Cream Maker™ are typically mixed in the oil phase.
   • CreamMaker EG™ can be mixed in the water phase, oil phase, or during emulsification.

2. Mixing Water-Soluble Active Ingredients: It is generally correct to add water-soluble active ingredients to the water phase after the water has been measured. It is not recommended to add water to the active ingredients that have been gathered together first.

3. Mixing Formulations with Silicone, Water, and Oil: When a formulation contains silicone, water, and oil, the mixing order still primarily depends on the emulsifier or cream maker used to combine the water and oil/silicone phases. Silicone ingredients are often mixed into the oil phase or a dedicated silicone phase. The emulsifier then helps to create a stable emulsion of the combined oil/silicone phase with the water phase. Always refer to the specific mixing instructions for your chosen emulsifier and silicone ingredients.

   • For example, Silicone Gel (Medium Gloss, Natural Olive Oil Base), Silicone Film (Soft Film, Low Viscosity, Cyclopentasiloxane Base), and Silicone Gel (High Gloss, Dimethicone Base) are typically mixed in the oil or silicone phase.

Always follow the specific mixing instructions provided for each ingredient, especially the emulsifier, to ensure a stable and effective formulation.
