Standard Operating Procedure for Use of Lubricants in Powders Production

1) Purpose

The purpose of this SOP is to provide guidelines for the proper use of lubricants in the manufacturing of powders within the pharmaceutical industry. Lubricants are essential for improving powder flow properties, preventing adhesion, and ensuring uniformity during processing.

2) Scope

This SOP applies to all personnel involved in the powders production within the pharmaceutical manufacturing department, particularly those handling and using lubricants.

3) Responsibilities

Production Operator: Responsible for adding lubricants as per batch requirements and following SOPs.
Quality Control (QC) Analyst: Responsible for monitoring lubrication parameters and conducting quality checks.

4) Procedure

1. Lubricant Selection:
   1. Consult the formulation or process development team to determine the suitable lubricant based on product requirements.
   2. Verify the availability and suitability of the selected lubricant for the intended powders processing.
2. Preparation and Addition of Lubricant:
   1. Prepare the lubricant blend or solution according to the specified concentration and method (e.g., dry blending, wet granulation).
   2. Add the lubricant blend to the powder formulation gradually while mixing to ensure uniform distribution.
3. Processing and Mixing:
   1. Mix the lubricated powder blend thoroughly to ensure homogeneity and uniform coating of particles.
   2. Monitor processing parameters such as mixing time, temperature, and humidity to optimize lubricant effectiveness.
4. Quality Control Checks:
   1. Perform tests
