Application

• The emulsions prepared from regenerated lignocellulose nanofibrils (RLCs) are suitable for applications in technical emulsions like tack coating and fog sealing, and are anticipated to be used in industries such as food, medical science, and cosmetics.

Description

Scientists from China and Pakistan have developed a novel two-step process to extract regenerated lignocellulose nanofibrils from sisal fibers, which are rich in cellulose and hemicellulose. This green solvent method involves dissolving sisal fibers in phosphoric acid, followed by regeneration and ultrasonication to create oil-in-water Pickering emulsions. The study demonstrated the biodegradability, stability, and cost-effectiveness of these emulsions, suitable for applications in food, cosmetics, and medical sciences. The research highlights a sustainable method for producing green emulsions from an abundant and renewable resource.

Pathway Description:

The process involves dissolving sisal fibers in phosphoric acid, adjusting the conditions to regenerate nanofibrils, and then using centrifugation to concentrate them. These nanofibrils are used to create oil-in-water emulsions, which are then tested and analyzed using different methods.
