Preparing Prototype Formulations for Formulation Development

1) Purpose

The purpose of this SOP is to provide guidelines for preparing prototype formulations during the formulation development process, ensuring consistency, reproducibility, and alignment with project objectives.

2) Scope

This SOP applies to all formulation development projects within the organization, covering the preparation of prototype formulations from initial formulation design to final evaluation and documentation.

3) Responsibilities

The responsibilities for this SOP include:
Project Manager: Overseeing the prototype formulation preparation and ensuring adherence to project timelines and goals.
Formulation Scientists: Formulating prototypes according to defined formulations and procedures.
Quality Assurance: Reviewing and approving the prototype formulation documentation and results.

4) Procedure

4.1 Formulation Design

1. Review the formulation design parameters and requirements.
2. Select appropriate excipients and their quantities based on the formulation goals.
3. Document the formulation design plan.

4.2 Prototype Formulation Preparation

1. Accurately weigh and measure each component of the formulation.
2. Follow the specified mixing order and technique to ensure uniform distribution.
3. Prepare the prototype formulation batches in accordance with the design plan.

4.3 Quality Control Checks

1. Perform in-process checks to verify the accuracy of ingredient quantities and mixing steps.
2. Conduct preliminary tests (e.g., pH, viscosity) to assess initial product attributes.
3. Document all quality control checks and results.

4.4 Evaluation and Testing

1. Evaluate the physical
