TitanSolidTM is completely safe for humans
Various media outlets have reported on possible negative health effects of exposure to titanium dioxide (TiO2). These concerns apply solely to cases of exposure to extremely high concentrations of TiO2, such as during the production process or use of the compound in powder form. These concerns do not apply to the TitanSolidTM product, developed by LumiChem.
Titanium Dioxide is widely used as a dyeing agent in the food, cosmetic and pharmaceutical industries. In its Regulation (EC) No 1333/2008 of December 2008 on food additives, the European Parliament and Council of the European Union approved titanium dioxide as a food additive and labeled it with code E171. TiO2 can be found in everyday products like chocolate, chewing gum, toothpaste and pharmaceuticals.
TiO2 can also be found in over 80% of all plastic.
The French Institute INRA (Institut national de la recherche agronomique) conducted studies on the risks associated with TiO2 as a food additive. Due to inconclusive evidence that consumption of TiO2 is safe for humans, the French government has banned its use as a food additive as of 2020.
The INRA did conclude, however, that TiO2 may have carcinogenic effects. These results were obtained from animal studies, in which animals received oral doses of powdered TiO2. Rats were given 0.1 mg and 10 mg/kg of bodyweight for 7 days and similar amounts for the next 2 months.
It is important to note that this study pertains to TiO2 in powdered form, a form the compound takes only during the production stage. While the above studies were ongoing, a separate study was conducted to monitor 24 thousand workers employed in 18 plants producing titanium dioxide. None of the sites reported any illnesses related to inhalation of TiO2.
Lumichem’s product is not and will NEVER be offered to clients in powdered form.
TitanSolid contains <0.9% TiO2
TitanSolidTM is not meant for human consumption and is to be applied ONLY to surfaces by trained professionals. It contains <0.9% TiO2 by volume. The rats in the INRA studies were given doses five times higher than is allowed in industry. This would correspond to a person ingesting an amount of TitanSolidTM needed to cover 250 square meters of surface area, a feat which would be physically impossible.
As a comparison, let us look at recommended daily allowances for salt – NaCl. According to the American College of Cardiology, the daily dose of sodium should not exceed 1500 mg (about 3.6 grams of salt) per person, regardless of age, weight or physical health. The American Heart Association concludes that excessive salt consumption may lead to 500 thousand to 1.2 million deaths from cardiovascular disease in America alone. But how much is 1500 mg? It may seem like a lot, but the average American consumes more than 3500 mg daily. One teaspoon of salt alone contains 2300 mg of sodium.
Central Institute For Labour Protection (CIOP-PIB) Safety Study
With the health and safety of our clients in mind, LumiChem asked the Central Institute For Labour Protection’s National Research Institute to conduct extensive tests on TitanSolidTM in order to determine the concentration of TiO2 particles released into the surrounding environment both during application of the product as well as after its completion. We asked the Institute for its opinion on the safety of our product for the end user – the person who comes into contact with the product without any special protective clothing.
The tests showed that TitanSolidTM permanently bonds with the substrate on a molecular level, creating a durable, stable and non-removable coating. Exposure of the coating to abrasive agents and mechanical abrasion did not lead to the release of TiO2 particles into the air.
Measurements taken with the use of a MiniWRAS meter recording concentrations of particulates in the PM10, PM2.5 and PM1 fractions confirmed the results obtained from DiscMini nanoparticle meters. An increase in the concentration of micrometric particulates occurs only during the TitanSolidTM layering process and is related to the spraying of the TitanSolidTM aerosol.
Analyses of air samples taken in the room did not contain titanium dioxide compounds, even when the room was under heavy use and desks coated with TitanSolidTM were subjected to abrasion during 24 hours from the start of measurements. This confirmed that the nanolayer of titanium dioxide was permanently bonded to the substrate. The TitanSolidTM coating does not detach from a coated surface even under heavy abrasion and scraping.
The European Union’s Position
The European Union, in its position statement of November 13, 2019, confirmed that only powder products containing TiO2 particles (with diameter less than 10 μm) and concentrations greater than 1% would be classified as potentially carcinogenic. Liquid mixtures (e.g. coatings) and solid mixtures are not classified as hazardous.
