Although you may not know the brand of cosmetics that you use for your face care contains ingredients with dimensions of nanoparticles (nanoingredients) able to penetrate your skin easily. What is nanotechnology? Nanotechnology is a field of applied science devoted to the control and manipulation of matter at a scale smaller than a micrometer ie the level of atoms and molecules (nano). Currently working on a range of one to one hundred nanometers (100-100 nm). Question of Size To get an idea of magnitudes we are talking about then are defined length units and establishing the relationships between them. The meter is the unit length of the International Unit System.
It is called: m. The millimeter is a unit of length equal to one thousandth of a meter. It is called mm. The micrometer is a unit of length equal to one millionth of a meter. It is called m and is also known as Micron (plural Latin micron). NM is the unit of length equal to one billionth of a meter. It is called nm.
1 nm = 1 x 10-9 m = 1 x 10-6 mm = 1 x 10-3 m 1 micron = 1,000 mm = 1,000,000 nm 1 nm 1 m = 1 billion m Although cell size is relation to its function, most eukaryotic cell has a diameter between 10 and 100 im (exceptions). Usually the size is constant for each cell type, independent of body size, ie, a kidney cell of a horse is the same order as that of a mouse. The difference in body size is due to the number of cells and not the size of them. Why Cosmetic manufacturers use ingredients with dimensions of nanoparticles in their products? Precisely because of its ingredients with small dimensions of nanoparticles can penetrate the skin and exert therapeutic effects. What is the Government Control of Nanotechnology? There is still no specific legislation controlling the use of nanotechnology in cosmetics and hygiene products. Nor are there sufficient studies on the safety of ingredients with dimensions of nanoparticles used in cosmetics. Of the few studies that have been done if it is known that nanoingredients through the skin and disappear. Still being studied, where they terminate. There is only the REACH legislation, current legislative framework for chemicals. Meanwhile, because the existing legal vacuum, cosmetics manufacturers including L’Oreal at the top continue to incorporate in its cosmetics and personal care ingredients with nanoparticle size. What …? possibly be thinking. For only tell that by using cosmetic ingredients on the size of nanoparticles (nanoingredients) forget the “barrier effect” or the protection it provides your skin, because these nanoingredients could penetrate the skin without difficulty, reach the bloodstream, result 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 to neutralize foreign agents that may prevent the “invasion” of nanoingredients. But the truth is that nobody knows what might happen and what would be the effects on their health. In the end, you decide because you are solely responsible for their health.
