Cellulose nanofibril-based oil-in-water pickering emulsions
Explore the innovative use of cellulose nanofibrils (CNFs) in creating versatile oil-in-water Pickering emulsions. These emulsions offer adjustable microcapsule size and release profiles, ensuring sustainability through biodegradability.
Overview
Cellulose nanofibril (CNF)-based oil-in-water Pickering emulsions represent a breakthrough in sustainable emulsion technology. Utilizing the natural amphiphilicity and nanosize of CNFs, these emulsions provide a biodegradable alternative for encapsulating hydrophobic ingredients. Their versatility is highlighted by adjustable microcapsule sizes and customizable active ingredient release profiles, making them suitable for various industrial applications, including pharmaceuticals, cosmetics, and food.
Technical specifications
Key features:
- Amphiphilic CNFs: Facilitate stable emulsion formation by serving as natural surfactants.
- Adjustable microcapsule size: Achieved by varying CNF concentration, oil-to-water ratio, and ultrasonication parameters.
- Customizable release profiles: Enhanced by post-coating with biomass-derived nanofibers or nanoparticles.
- Biodegradability: Ensured by the use of cellulose materials, adhering to eco-friendly practices.
The emulsions are characterized using advanced techniques such as optical microscopy, confocal laser scanning microscopy, SEM, IR, AFM, and TGA to assess size, surface coverage, ingredient loading, and durability.
Technology readiness level
Currently at TRL 4, this technology has been validated in a laboratory setting with ongoing efforts to optimize and characterize the emulsions for various applications. Further validation will involve fine-tuning the emulsions based on hydrophobic ingredient properties and conducting biodegradability tests.
