Tecnochimica has launched a completely TiO2 free productionTitanium dioxide is widely used in various fields. But recent research has raised concerns regarding its potential toxicity.
Titanium dioxide is a pigment commonly used to give an opaque effect and a white background. It is used in numerous industries, ranging from food (confectionary, sauces) to cosmetics (sun filters, toothpaste) and can also be used in many industrial applications (dyes, paints). Its massive and generalized use, however, spreads the shadow of suspicion: what if titanium dioxide is not so harmless?
Moreover, the chemical world is constantly being updated and many substances that were once classified as “not dangerous” today could be put into question. It should be said that there is currently no certain evidence of the potential toxicity of titanium dioxide. But research conducted by numerous entities, from different fields and not connected with each other, start to raise more than one doubt.
The Risk Assessment Committee of the European Chemicals Agency has recently included titanium dioxide, when inhaled, in Group 2B, i.e. substances “potentially carcinogenic to humans.” This category is used for agents where there is limited evidence of carcinogenicity in humans and less than sufficient evidence of carcinogenicity in experimental animals. Among doubts and suspicions, and in view of a possible ban, Technochimica SpA has solved the problem at the source by eliminating the use of titanium dioxide.
Thanks to intensive research, the laboratories of the company based in Castelfranco di Sotto have developed new polymers that, in combination with resins and synthetics, make the hides very white and resistant without the use of the suspected TiO2. This results in many features such as obtaining leather with fine and lacquered grain (that seems to be “almost finished”), very uniform surfaces on which to mask or colour the defects without having to resort to clear/dark colouring, clean and complete dyes and greater compliance with the standard systems.
The finished leather has good absorption and high resistance to printing, where it does not turn grey but, on the contrary, becomes clean and bright, especially when treated with fluorescent or pastel colours. An eco-friendly re-tanning system characterised by sulphate and COD levels lower than the requirements of various water purification consortiums.
