Inorganic Nanofibers Could Replace Objectionable Nanoparticles in Cosmetic Products

(Nanowerk News) The Czech company Kertak Nanotechnology s.r.o, is the first supplier of inorganic nanofibers on an industrial basis in the world and is currently in negotiations with the world’s largest cosmetic producers relating to the application of titanium white based nanofibers (TiO2) in cosmetics.
Based on the latest research, nanofibers are the desired solution to the problems faced by using nano-particles in cosmetic products, mainly those producing sun protections creams. The unique property of nanofibers completely eliminates the possible negative influence on consumer health while retaining the whitening effects of nano-particles. „The enormous demand of the world’s leading cosmetic producers confirms our assumption about the strategic importance of nanofibers in the cosmetic industry”, stated Ladislav Jandácek, Executive Head of Kertak Nanotechnology s.r.o.
The rapid introduction of nanotechnologies into the cosmetic industry in 2008 was slowed down by concerns about the possible negative effects of nano-particles on human health. Britain’s certification agency SA Cert stated that it will not certify products as “BIO” as long as they contain substances produced using nanotechnologies. Scientists were concerned that nano-particles in creams applied to skin may infiltrate body membranes. Such concerns influenced many leading cosmetic and suntan creams producers, who had been adding nano-particles to their products. Companies such as L´ Oréal, Unilever and Boots were forced to search for alternative methods.
The solution to these health issues has finally come in year 2009 with the opening of the first and unique industrial line for production of inorganic nanofibers in the world. Nanofibers markedly improve the properties of products and their added value. One of the basic properties of nanofibers is large specific surface and high porosity.
Inorganic nanofibers would mainly find their usage in the cosmetics industry. A new type of production link based on technology Nanospider™ enables vast improvements in the quality of skin protection creams for example. Titanium white (TiO2) in the form of nanofibers has the same whitening effect as the nano-particles that were used formerly. While nano-particles may infiltrate into inner body membranes, nanofibers remain on the surface of the skin. Titanium whitening effect caused by nanofibers represents a successful return of nanotechnologies to the cosmetics industry.
