PURETi™ is committed to producing a safe product that is beneficial to human health and the environment by destroying airborne pollutants.  We take concerns about product safety seriously and will continue keep our customers informed of the latest developments. 

PURETi’s claims have been tested and proven at top national, university and independent laboratories, and the US Space Agency

  • Queens IPS (Belfast, N Ireland)
  • Certech (Seneffe, Belgium)
  • Louisiana State University (USA)
  • Stony Brook University (New York, USA)
  • University of Ferrara (Italy)

PURETi™ is a NASA Dual Use Technology Partner.

PURETi™ is the winner of 6 major awards for innovation in sustainability and environmentally beneficial products.

PURETi™ has been successfully applied to 2+ million square feet of buildings and building materials.

All PURETi™ products have been registered safe by the National Sanitation Foundation.

PURETi’s safety profile has been tested and verified by multiple independent sources (NSF, NIOSH, Bureau Veritas).

The active ingredient in PURETi™ is titanium dioxide or TiO2. The solutions PURETi™ are manufactured in the United States to FDA – approved specifications for quality control. The products PURETi™ contain 98% – 99% water, 1% – 2% of TiO2 in both amorphous and crystalline form and a tiny fraction of wetting agents.

TiO2 is the ninth most common mineral on the planet, widely used in paints, cosmetics and food stuffs and has been extensively studied for its health and environmental impacts.

The US FDA has classified TiO2 as GRAS (Generally Recognized as Safe).

The National Sanitation Foundation has registered PURETi™ is safe for surface contact of materials. NIOSH has studied and found that the methods of application of PURETi™ are safe. The solutions PURETi™ have passed the California Aquatic Toxicity Test.

PURETi™ is safe in the bottle, safe during application and safe once applied. There are no respirable powders with PURETi™ and near zero risk of human contact.

Independent university tests have found that applied mineral films PURETi™ require a great deal of force to wear and that, if worn, will wear on flakes greater than 100 nm and above the threshold of concern.

PURETi™ is a mineral oxide film former that contains nano-particles of titanium dioxide (TiO2), but these particles are dispersed in an inorganic liquid matrix.  Liquid solutions of TiO2 are different from the powder forms of TiO2 that have been the focus of new EU regulations.

PURETi™ can be safely applied following the labeled instructions.  All of our products have been tested by independent laboratories and/or the National Institute of Occupational Safety and Health (NIOSH).  Exposure levels to the applicator and in the background areas are extremely low, and well below any threshold of concern.

Once applied, PURETi™ is durably bonded to the surface.  The general public need not have any concern being around PURETi™ treated surfaces, and in fact should benefit from the cleaner, healthier air being created by those surfaces.  Materials coated in PURETi™ do not require any type of safety labeling.

Recent EU Regulatory Changes

In 1995, scientists conducted research on laboratory rats where the rats were exposed to high levels of titanium dioxide fine and ultrafine powders.  Some of the rats developed lung tumors from exposure to these high doses of powders.  Similar results were not found in other laboratory animals, nor in primates.  Based on these findings, however, IARC (the International Agency for Research on Cancer) in 2010 classified TiO2 as a Class 2B carcinogen “possibly carcinogenic to humans.”   In the body of that decision IARC noted that there was inadequate evidence in humans for carcinogenicity, but that their decision was based on experimental animals.

After a decade of debate, effective October 2021, the European Union began enforcing new labeling requirements for products that contain powdered titanium dioxide

“The classification of certain forms of titanium dioxide (TiO2) as suspected carcinogens by inhalation was published on 18.02.2020. The hazard class Carc. 2 was assigned with the hazard statement H351 (inhalation) ‘suspected of causing cancer (inhalation)”  Source: ECHA Guide on the Classification and Labelling of Titanium Dioxide September 2021.

“Classification as Carc. 2, H351 (inhalation) is linked to some powder forms of the substance. It is therefore triggered only on the basis of the specific fraction of particles which is effectively responsible for the health effect. In this context, ‘powder’ refers to the specific physical state of the substance.”  Source: ECHA

The European Council of manufacturers of paint, printing ink and artist colours (CEPE), was among several industry organization opposing this change, partly on the basis that it sets a dangerous precedent for other powdery substances.

“The reasons behind the EU Commission’s decision are not related to the chemistry of titanium dioxide, but by the simple presence of dust particles in excessive quantities in the lungs, causing chronic inflammation of the lung cells in rats.” Source:  EU publishes official regulation on titanium dioxide

The new EU regulations specifically note that liquid mixtures such as PURETi™ are NOT included in the Class 2B classification.

Section 4.2  Liquid mixtures containing titanium dioxide do not require classification as Carc. 2, H351 (inhalation). However, they shall be labelled with the supplemental labelling element EUH211 if they contain at least 1 % (w/w) of titanium dioxide particles with an aerodynamic diameter of 10 μm or less.  EUH211: ‘Warning! Hazardous respirable droplets may be formed when sprayed. Do not breathe spray or mist.’

PURETi™ coatings contain very small amounts of titanium dioxide.  PURETi® Coat™ is our only commercially available product with a wet weight TiO2 content >1%.   When sold in the EU it will contain the required warning about breathing droplets while it is being sprayed.  This product is only applied by trained operatives. Our safety instructions have always included wearing a mask while spraying Coat as a matter of standard safety practice.  PURETi Clean & Fresh™ and PURETi Clear™ are both below this threshold and therefore do not require any labeling.
