Standard Operating Procedure for Emulsification in Cream Manufacturing
1) Purpose
The purpose of this SOP is to outline the steps required for the emulsification process in the production of creams in a pharmaceutical manufacturing setting to ensure uniformity, consistency, and compliance with regulatory standards.
2) Scope
This SOP applies to all personnel involved in the emulsification of creams within the pharmaceutical production facility. It covers the preparation, operation, and maintenance of the emulsification equipment.
3) Responsibilities
The purpose of SOP here
4) Procedure
4.1 Preparation of Equipment and Materials
4.1.1 Ensure that all equipment and utensils are clean, calibrated, and in good working condition.
4.1.2 Verify the availability of all required raw materials and excipients.
4.1.3 Set up the production area according to GMP guidelines.
4.2 Weighing and Heating of Ingredients
4.2.1 Weigh the oil phase ingredients (e.g., oils, waxes) as per the formulation sheet.
4.2.2 Heat the oil phase ingredients in a jacketed kettle to the specified temperature (e.g., 70-80°C) to melt the waxes and homogenize the mixture.
4.2.3 Weigh the water phase ingredients (e.g., water, glycerin, preservatives) as per the formulation sheet.
4.2.4 Heat the water phase ingredients in a separate vessel to the same temperature as the oil phase.
4.3 Emulsification Process
4.3.1 Gradually add the oil phase to the water phase with continuous stirring using a high-shear mixer.
4.3.2 Maintain the specified mixing speed and time to ensure a uniform emulsion is formed.
4.3.3 Monitor the temperature to ensure it remains consistent throughout the process.
4.3.4 Perform in-process checks for consistency and homogeneity of the emulsion.
4.4 Cooling and Final Mixing
4.4.1 Once the emulsification is complete, begin cooling the emulsion to room temperature while maintaining gentle stirring to prevent separation.
4.4.2 Add any temperature-sensitive ingredients (e.g., preservatives, active ingredients) during the cooling phase as per the formulation instructions.
4.4.3 Ensure thorough mixing of all components to achieve a homogeneous final product.
4.5 Post-Emulsification Checks
4.5.1 Transfer the emulsion to a suitable storage vessel or proceed to the next processing step.
4.5.2 Perform quality control tests on the emulsion, including checks for particle size, viscosity, and stability.
4.5.3 Document all process parameters, observations, and results in the batch record.
4.6 Equipment Cleaning and Maintenance
4.6.1 Clean the emulsification equipment according to the cleaning SOP to prevent cross-contamination.
4.6.2 Perform routine maintenance and calibration of the equipment as per the maintenance schedule.
4.6.3 Record all cleaning and maintenance activities in the equipment logbook.
