Nanotechnology in cosmetic products might not be considered a new technology, as liposomes were introduced to the market in the 1980\u2019s. Since then we\u2019ve seen the rise of several trends, including peptides, proteomics, stem cells and epigenetics. Howsoever, cosmetic companies including L\u2019Oreal, P&G, Henkel, Unilever, Dior and Johnson & Johnson publish several nanotechnology-related patents every year, which means that investments in this research area are relevant to this day.<\/p>\n

What are cosmetic nanomaterials?<\/h3>\n

The EU Regulation 1223\/2009 defines the term \u2018nanomaterial\u2019 as an \u201cinsoluble or biopersistant and intentionally manufactured material with one or more external dimensions, or an internal structure, on the scale from 1 to 100 nm\u201d. Under this regulation, many biodegradable nanoparticle formulations used in cosmetic products are not considered nanomaterials and many suppliers are using this fact to name their ingredients \u2018submicron particles\u2019 instead of \u2018nanoparticles\u2019. Uncertainty and bias usually accompanies the surge of new technologies, which is the case with nanotechnology; many cosmetic companies are unclear in their communications about what technologies are used in their products.<\/p>\n

More importantly, one should be reminded that nanotechnology includes the \u201cunderstanding and control of matter and processes at the nanoscale, typically, but not exclusively<\/em>, below 100 nanometres in one or more dimensions where the onset of size-dependent phenomena<\/em> usually enables novel applications\u201d as defined by the ISO\/TC 229. Accordingly, submicron particles act as delivery systems and convey different properties to materials in that size range, hence they will be considered nanoparticles in the scope of this article.<\/p>\n

The size-dependent phenomena nanoparticles present are primarily linked to the higher surface area of particles in the nanoscale, which alter their optical properties (e.g. inorganic sunscreens will look transparent upon application on skin), and encapsulated fragrances can last longer and perform better. In addition, nanostructures can:<\/p>\n
