Ultrastable Nanoemulsions In Disordered And Ordered States

Summary

Researchers in the Department of Chemistry and Biochemistry at UCLA have developed a method for the production of crystalline, iridescent emulsions stable to repeated dilutions.

Background

Many existing nanoemulsion formulations suffer from instability, especially with regards to dilution. To prevent the nano-droplets from coalescing, more and more stabilizing agent must be added as the emulsion concentration is reformulated for application.

Innovation

Applications

• Drug delivery 
• Cosmetics 
• Agrochemicals 
• Food additives 
• Healthcare broadly

Advantages

• Stabilized by crystal packing rather than weak electrostatics 
• Repeated dilution does not alter morphology 
• Easily produced and isolated
