The various reasons for this nanotoxicity are summarized below:- Smaller size of nanoparticles The main characteristic of nanoparticles is their small size. Shape of nanoparticles Nanoparticles are produced in a variety of shapes like spheres, tubes, sheets etc. Surface area of nanoparticles As the size of the particle decreases, their surface area increases leading to an increase in their reactivity. Penetration of nanoparticles via skin Scientific studies have shown that nanoparticles can penetrate skin, especially if skin is flexed.
Cellular toxicity of zinc oxide and titanium dioxide nanoparticles In a study published by Minghong Wu and co-workers at Shanghai University, they have discovered that zinc oxide ZnO nanoparticles used in sunscreens can damage or kill the stem cells in the brains of mice. Occupational risks of nanoparticles Workers may be accidentally exposed to nanomaterials during the production of nanomaterials or products containing them, as well as during use, disposal or recycling of these products. Route and extent of exposure[ 44 — 46 ] health risks that nanoparticles pose to the humans also depend on the route and extent of exposure to such materials.
Inhalation It is the most common route of exposure of airborne nanoparticles according to the National Institute of Occupational Health and Safety. Ingestion Ingestion of nanomaterials may occur from unintentional hand-to-mouth transfer of nanomaterials or from the intentional ingestion of nanomaterials.
Through skin Studies have shown that certain nanomaterials have penetrated layers of pig skin within 24 hours of exposure. Environmental risks of nanoparticles The environment is also at risk due to the exposure of nanomaterials through release into the water, air, and soil, during the manufacture, use, or disposal of these materials. Toxicity produced by carbon fullerenes buckyballs Various studies have shown that carbon fullerenes, which are currently being used in moisturizers and some face creams, have the potential to cause brain damage in fishes[ 55 , 56 ] kill water fleas and have bactericidal properties.
Characterization methods for safety assessment of nanoparticles in cosmetics The opinions of the Scientific Committee on Emerging and Newly Identified Health Risks SCENIHR deals with the risk assessment methodologies available for evaluating the possible adverse health and environmental effects of nanotechnology products[ 59 ] and also on the investigation of nanomaterials.
Mathematical modeling These predictive models range from simple, empirical algorithms to complex mathematical equations which sometimes require knowledge and estimation of experimentally inaccessible parameters. Microscopic techniques More useful information from the in vitro studies can be obtained by microscopic examination of the skin posttreatment. In vitro methods Though there are a number of alternative methods and technologies for studying the molecular mechanisms involved in the biological activity of compounds, only validated methods are permitted for cosmetic products.
Figure 1. Figure 2. Safety requisites for a blooming beauty Cosmetic manufacturers using nanotechnology confront an uncertain future from both consumer response and a regulatory standpoint. Prior to placing the cosmetic product on the market, the responsible person should submit the following information to the Commission: The presence of substances in the form of nanomaterials Their identification including the chemical name IUPAC and other descriptors The reasonably foreseeable exposure conditions In case the Commission has concerns regarding the safety of the nanomaterial, the Commission shall, without delay, request the SCCS to give its opinion on the safety of these nanomaterials for the relevant categories of cosmetic products and the reasonably foreseeable exposure conditions.
Particular consideration shall be given to any possible impacts on the toxicological profile due to Particle sizes, including nanomaterials; Impurities of the substances and raw material used; and Interaction of substances.
