Titanium dioxide powder is frequently used as a pigment in the production of colours and paints. Last year, the EU Commission classified it as suspected to be carcinogenic when inhaled. Therefore, new regulations apply as of October 2021. Daniel Müller, Senior Business Development Manager at BASF Colors & Effects explains in the interview how the classification of TiO2 affects the manufacturers of colours and paints and which alternatives there are.
The new regulations have completely changed our starting position. Products with certain amounts of titanium dioxide then need to have warning notices or be labelled as potentially carcinogenic. Of course, manufacturers would like to avoid this. But stricter rules will also apply in production starting in autumn. Therefore, suitable protective measures need to be taken to prevent the inhalation of the material.
Titanium dioxide is used as a white pigment in powder form in order to achieve a hiding power of colours and paints. There is no other equivalent pigment. However, manufacturers can compensate the hiding power with other titanium dioxide-based products, as we do with our liquid pigment preparations Luconyl®, Luconyl® NG and Dispers®. There are no labelling requirements for these alternative products and they are easier to handle in production.
Firstly in regard to safety: customers who have been using titanium dioxide know very well that the dust formation leads to a contamination of surfaces and production systems time and again. With these liquid products, there is no danger of inhaling particles. Secondly, liquid products are generally easier to handle in production than those in powder form. The reason for this is simple: They do not cause dust, which in turn reduces the cleaning effort, and they are also easy to dose.
Our products Luconyl®, Luconyl® NG and Dispers® White, which we developed at BASF Colors & Effects and now offer to our customers together with BTC. They are each suitable for different industries and application areas.
Certainly. Manufacturers also benefit from a high reproducibility, as they receive a product that is ready for use and optimally adjusted with the liquid white pigments. After all, titanium dioxide can have different properties depending on the supplier or even have an inherent colouration which can negatively affect the reproducibility. With our liquid pigment preparation, we offer highly specified products which ensure the consistent quality of the end product.
There is no general answer to this question as the manufacturers use different formulations and powders cannot be replaced 1:1 with liquid products. Our Color Competence Center will gladly assist with calculations if necessary. You also have the option of registering via the BASF Colors & Effects «Pigment Finder (https://www.colors-effects.com)» and downloading additional product data.
Finding alternatives to titanium dioxide powder is more difficult here, but we are currently developing new solutions which remain under the limit values and are therefore not subject to labelling. These products could be used in dry colours for example. They are also an alternative for manufacturers who wish to maintain their usual production process without switching from dry to liquid components.
