Quality by Design-Based Scale-Up and Industrial Development of Turmeric Extract-Loaded Nanostructured Lipid Carriers

Area of Science:

• Pharmaceutical Sciences
• Nanotechnology
• Chemical Engineering

Background:

• Manufacturing challenges exist for scalable production of lipid-based nanocarriers, especially for sensitive compounds like curcuminoids.
• Developing robust processes for labile phytochemicals requires advanced formulation strategies.

Purpose of the Study:

• To establish a scalable, resource-efficient manufacturing process for curcuminoids-loaded nanostructured lipid carriers (NLCs).
• To integrate Quality by Design (QbD) and Outcome-Based Design (ObD) for process optimization.
• To define critical quality attributes and critical process parameters for reliable NLC production.

Main Methods:

• Employed a risk-based, knowledge-driven single-factor screening approach, avoiding extensive multivariate design of experiments.
• Utilized Ishikawa diagrams and failure mode analysis to select 12 processing conditions for defining the design space.
• Optimized a two-step homogenization process (high-shear homogenization followed by high-pressure homogenization) for nanoparticle refinement.

Main Results:

• Identified key critical process parameters (HSH speed, processing time, HPH cycles) influencing nanoparticle characteristics via multivariate data analysis (PCA, HCA).
• Achieved successful scale-up of NLCs from 100 g to 5000 g within an optimized 1-hour process.
• Demonstrated generation of nanosized particles (100-500 nm) with high encapsulation efficiency and improved physical stability using the combined HSH-HPH method.

Conclusions:

• Established a practical, industrially viable framework integrating QbD and data-driven optimization for NLC manufacturing.
• The developed process enables reliable translation from laboratory-scale to semi-industrial production.
• This QbD-driven approach ensures consistent quality and scalability for lipid-based nanocarrier production.
