1. Purpose
The purpose of this Standard Operating Procedure (SOP) is to establish a systematic approach for the formulation development of ointments. This ensures that the developed formulation meets efficacy, stability, and regulatory requirements.
2. Scope
This SOP applies to the Research and Development (R&D) department responsible for developing new ointment formulations. It includes ingredient selection, preliminary formulation trials, stability testing, and process optimization.
3. Responsibilities
- Formulation Scientist: Develops and optimizes the ointment formulation.
- Analytical Chemist: Conducts stability testing and compatibility studies.
- Quality Assurance (QA) Personnel: Ensures compliance with regulatory standards.
- Research and Development (R&D) Head: Approves the final formulation for further development.
4. Accountability
The R&D Manager is accountable for ensuring that all formulation trials and documentation are conducted as per regulatory and company standards.
5. Procedure
5.1 Selection of Ingredients
- Identify and select active pharmaceutical ingredients (APIs) based on therapeutic efficacy.
- Choose appropriate excipients, including emulsifiers, humectants, and preservatives.
- Ensure all ingredients comply with pharmacopeial standards (USP, BP, IP).
5.2 Preliminary Formulation Trials
- Prepare small-scale batches with varying compositions.
- Evaluate texture, spreadability, and initial stability.
- Adjust ingredient ratios to achieve the desired properties.
5.3 Stability Testing
- Conduct
accelerated stability testing at different temperature and humidity conditions.
Analyze physical, chemical, and microbial stability parameters.
Document any formulation changes required based on test results.
5.4 Process Optimization
- Define critical processing parameters such as mixing speed and temperature.
- Optimize heating, cooling, and homogenization processes.
- Conduct pilot-scale trials to validate formulation robustness.
5.5 Documentation and Approval
- Document all formulation trials, test results, and modifications.
- Prepare a formulation development report.
- Obtain final approval from the R&D Head before proceeding to pilot batch production.
