These are most often oil-in-water emulsions with droplet sizes ranging from 50 to 200 nm.
It is crucial not to confuse nanoemulsions with nanoparticles.
Nanoemulsions can be used in applications such as:
-
Alcohol-free perfume
-
Skincare
-
Makeup (lips, foundation)
-
Sunscreen
-
Haircare
-
Baby products
Alcohol-free perfume
-
Increase perfume solubility without adding extra solubilizers
-
Achieve an ultra-fluid galenic form
-
Reduce the amount of surfactants used for a more environmentally friendly formulation process
-
Promote better skin tolerance
-
Produce less irritating and less drying perfumes
Skincare
-
New galenic forms
-
Addition of reverse solubility actives while maintaining a transparent or translucent appearance
-
Reduce the viscosity of emulsions for improved sensory experience
-
Increase product tolerance
-
Enhance bioavailability
-
Improve emulsion stability due to their small size: fewer stabilizing additives
-
Improve the diffusion of active ingredients and product efficacy
Sunscreen
-
Improve SPF through the small size of the droplets
-
Enhance droplet monodispersity for better SPF
-
Improve spreadability
-
Enhance the texture and sensory experience of the product
Make-up
-
New galenic forms
-
Skinification of makeup / skincare makeup
-
Improve spreadability
-
Increase product tolerance
-
Enhance bioavailability
-
Improve the diffusion of active ingredients and product efficacy
Haircare
-
Improve product diffusion in hair due to the small size of the droplets.
-
Combine washing and hair care properties.
-
Enhance product performance compared to conventional emulsions through better penetration.
Baby skincare
-
New galenic forms
-
Reduce the viscosity of emulsions for improved sensory experience
-
Increase product tolerance
-
Enhance bioavailability
-
Improve the spreadability of active ingredients
