You may not know it is possible that cosmetics brand that uses for your face care contains ingredients with dimensions of nanoparticles (nanoingredientes) able to penetrate your skin without difficulty. What is nanotechnology? Nanotechnology is a field of applied sciences dedicated to the control and manipulation of matter at one less than a micrometer scale i.e. at the level of atoms and molecules (nanomaterials). Currently working in a range of between one and 100 nanometers (1 100 nm). Size issue to give us an idea of magnitude we are talking about here are defined some length units and establishing relationships between them. The metro is the unit of the international system of unit length.

is a unit of length equivalent to the thousandth part of a meter. Called mm. The micrometer is the unit of length equal to one millionth of a meter. M is called and is also known as micron (plural latino, micra). The nanometer is the unit of length that equals a billionth of a meter.

The size is generally constant for each independent of the size of the organism and cell type, i.e. a cell of the kidney of a horse is of the same order as a mouse. The difference in the size of the body is due to the number of cells and not the same size. Why the manufacturers of cosmetics using ingredients with dimensions of nanoparticles in their products? Precisely because of its small size the ingredients with dimensions of nanoparticles can penetrate the skin and exert therapeutic effects or cuasiterapeuticos. Whats the governmental Control of nanotechnology? There is still no specific legislation that controls the use of nanotechnology in cosmetics and hygiene products. There are enough studies on the safety of the ingredients with dimensions of nanoparticles used in cosmetics. Of the few studies that have been done if it is known that the nanoingredientes pass through the skin and disappear. He is still studying where end. There is only the current legislative framework for chemicals, REACH legislation.Meanwhile, because of the legal vacuum existing, manufacturers of cosmetics including L’Oreal to head still incorporating in their cosmetic products and toiletries ingredients with size of nanoparticles. So what? possibly you are thinking of. Well just say forget that when using cosmetics with ingredients of the size of nanoparticles (nanoingredientes) to the barrier effect or the protection that gives your skin, because these nanoingredientes could penetrate his skin without difficulty, reach the bloodstream, end up in any organ or tissue of the body, and penetrate their cells without difficulty. It is also true that not everything is so simple, and that our body has mechanisms of neutralization of foreign agents that would possibly prevent the invasion of the nanoingrediente. But the truth is that nobody knows that I could do and which would be your health effects. At the end, you decide because you alone are responsible for your health.
