Cosmetic Formulation Mixing Instructions

Based on the ingredients provided, this formula appears to be an emulsion (like a cream or lotion) which typically requires heating to properly combine the oil and water phases.

Here is a general mixing procedure:

1. Prepare the Water Phase: Combine water, Glycerin, PEG-7 Glyceryl Cocoate, PVP, and Polysorbate 20 in a heat-resistant container. Heat this phase, stirring gently, until it reaches approximately 75°C. PVP can tolerate heat up to 80°C for a short period.
2. Prepare the Oil Phase: In a separate heat-resistant container, combine Ceteareth 25, PEG 40 Hydrogenated Castor Oil, Beeswax, and Simethicone. Heat this phase, stirring, until it also reaches approximately 75°C and the Beeswax and Ceteareth 25 are fully melted and dissolved/dispersed.
3. Combine Phases: Slowly add the heated oil phase to the heated water phase while stirring continuously. Use a high-shear mixer (like a homogenizer or stick blender) for several minutes to create a stable emulsion.
4. Cooling: Continue stirring the emulsion as it cools down. This is important for the structure to form correctly.
5. Add Heat-Sensitive Ingredient: Once the emulsion has cooled below 60°C, add the Phenoxyethanol and stir until fully incorporated.
6. Final Adjustments: Continue stirring until the emulsion reaches room temperature. Make any final adjustments to viscosity or pH if necessary.

Heat is necessary in this formulation to melt the solid ingredients like Beeswax and Ceteareth 25 and to help create a stable emulsion when combining the oil and water phases.
