Nanotechnology

For ALTANA, product stewardship is an essential component of responsible management, and nanotechnology is no exception. We are convinced that nanotechnology can contribute to the optimization of systems in the fields of energy, climate protection, environment, and medicine. However, new substances, materials, and technologies not only open up new opportunities, but can also involve potential risks for humans and the environment.

Consequently, product stewardship also calls on us to safely assess potential risks and to implement effective measures for risk management before a product is introduced. In Germany, we follow the guidelines of the German Chemical Industry Association (VCI) and the German Institute for Occupational Safety and Health (BAuA). Accordingly, our risk management always assumes the greatest possible hazard and is based on stringent standards.

The discussion of potential risks primarily focuses on “free” or powdered nanomaterials, because they are most likely to enter the body through aspiration. When nanomaterials are bonded in a matrix, the risk of exposure is much smaller and can be prevented with further measures.

All nanomaterials supplied to customers by companies of the ALTANA Group are part of a matrix, which is at least a liquid. In final applications, the materials are then part of a coating or plastic matrix. ALTANA and BYK are taking part in studies of the German Coatings Association to investigate consequences of eventual release, for example from sanding or weather impact. Sanding results are already available and do not show any release of the integrated nanoparticles.

It is of equal importance to us to point out the general consensus among experts that nanotechnology per se does not pose a risk, and that at most, specific substances may be hazardous in nano format. Until this has been fully studied, the corresponding risk management measures should assume a high level of hazard. Unfortunately, no agreement has been reached on testing methods yet.

ALTANA promotes open dialog about nanotechnology. We provide our customers with information in the form of material safety data sheets that follow the corresponding VCI guidelines. Nevertheless, ALTANA considers end-product labels that state “contains nanomaterials” mostly unsuitable, since the term “nanomaterials” provides no information about hazards or risks, as explained above.
