Standard Operating Procedure for Operation of Vacuum Emulsifying Mixer

Purpose

The purpose of this Standard Operating Procedure (SOP) is to provide guidelines for the safe and efficient operation of the vacuum emulsifying mixer used in the formulation of cutaneous products. It aims to ensure that the equipment is operated correctly, minimizing the risk of product contamination and ensuring consistent product quality.

Scope

This SOP applies to all personnel involved in the operation of the vacuum emulsifying mixer in the formulation, manufacturing, and processing of creams, ointments, gels, powders, and pastes applied topically to the skin.

Responsibilities

Production Operators: Responsible for operating the vacuum emulsifying mixer in accordance with this SOP and manufacturer’s instructions.
Quality Assurance (QA): Responsible for verifying the proper operation of the vacuum emulsifying mixer and conducting in-process checks to ensure product quality.
Engineering Department: Responsible for maintenance and calibration of the vacuum emulsifying mixer to ensure optimal performance.
Supervisors: Responsible for overseeing the operation of the equipment and ensuring compliance with safety protocols.

Procedure

Preparation: Ensure that the vacuum emulsifying mixer is clean, sanitized, and free from any residual product or contaminants.
Setup: Set up the equipment according to the formulation requirements, including adjusting speed settings, temperature controls, and vacuum levels.
Ingredient Addition: Gradually add the required ingredients into the

mixing vessel, following the specified order and ensuring proper dispersion.

Emulsification: Start the mixing process and gradually increase the speed to achieve the desired emulsion consistency, maintaining a vacuum as necessary.

Temperature Control: Monitor and control the temperature of the emulsion throughout the mixing process to prevent overheating or thermal degradation.

Sampling: Take samples at regular intervals to check for uniformity, viscosity, and other critical parameters as per the batch record requirements.

Cleaning: After completion of the mixing process, thoroughly clean and sanitize the equipment according to the cleaning SOP.

Documentation: Record all relevant process parameters, including mixing time, speeds, temperatures, and any deviations encountered during the operation.

Post-Operation Checks: Conduct visual inspections of the equipment to ensure that all components are intact and functioning properly before proceeding to the next batch.

Shutdown: Properly shut down the vacuum emulsifying mixer, including turning off power sources, releasing vacuum pressure, and securing all moving parts.
