Integration of nanotechnology and nanoparticles in cosmetic formulations is an exciting field but a cautious approach is needed, considering safety, toxicology and environmental impact. According to a review published in Next Nanotechnology [1], significant advances have been made with nanoparticles in cosmetics but deeper and longer-term research is required.
As far as cosmetic products are concerned, nanotechnology is the practice of integrating nanoparticle – i.e. microscopic particles ranging from 1 to 100 nanometers – into formulations. These nanoparticles can be active, functional or carrier ingredients offering various advantages, such as enhanced bioavailability, improved penetration, targeted delivery, increased stability and even novel textures.
