3.1 Polymer nanoparticles

Generally speaking, nanoparticles can be used to stabilize active ingredients, or for the controlled release of an active ingredient that is more fragile than liposomal formulations. They are produced from a wide range of natural and synthetic sources in the form of stable liquids and powders. Nanoparticles are used in virtually every type of body care product on the market, from sunscreens and anti-aging creams to toothpastes. Among polymer nanoparticles, we distinguish between dendrimers and nanocapsules.
