Nanoparticles in toothpaste are extremely dangerous!!!
Nanoparticles of whitewash damaged the genome of miceCopper news
American scientists have found that nanoparticles of the most common white dye cause damage to the genome of mice, which increases the risk of developing malignant neoplasms, writes ScienceDaily (Nanoparticles Used in Common Household Items Cause Genetic Damage in Mice).
Researchers from the University of California at Los Angeles added titanium dioxide (TiO 2) nanoparticles - the most common dye for cosmetics, tablets, toothpaste and many other products –to the drinking water of laboratory mice.
Within five days, damage to the genome in the form of single- and double-stranded DNA breaks and chromosome deformations was observed in animal cells. In addition, the nanoparticles caused inflammatory reactions. Both of these factors significantly increase the risk of developing cancer.
According to the researchers, a five-day intake of nanoparticles with water by mice is equivalent in humans to 1.6 years of work in production using titanium dyes.

It is not yet clear whether the risk increases with increasing duration of contact with nanoparticles.
As explained by the head of the work, Professor Robert Schiestl, dyes based on titanium dioxide were considered absolutely harmless, since this substance is chemically inert and does not react with body molecules. Because of this, the detected effect is not toxicity in the usual sense – it is a physico-chemical effect.
In the process of obtaining nanoparticles, their total surface area increases many times, and the size becomes such that they can penetrate into the cell. Interactions of molecules on the surface of inert particles lead to the formation of free radicals, which are strong oxidants and damage DNA. Such a mechanism of toxicity was discovered for the first time.
According to Schistl, titanium dioxide nanoparticles can enter the body by inhalation and ingestion, but not through the skin, so lotions and creams containing them (but not aerosols) are completely safe.
The global production of TiO 2 nanoparticles is about two million tons per year. They are included in hundreds of products that we come into contact with in everyday life.
(We repeat what was written in the announcement of the horror story: to protect yourself from this terrible danger, it is enough not to eat a tube of toothpaste every day and not to use perspirant deodorants instead of snuff - VM.)
