Nanomaterials in Commercial Aerosol Products on the Danish Market


The report examines the use of aerosol products where nanomaterials are part of the liquid to be brought in spray form. Very few aerosol products with nano are found on the Danish market. The identified products were: cleaning products, waterproofing products and paint. The nano content in many of the products is in the form of ordinary pigments which are nano-sized. A simple risk assessment suggests the same risk profile of aerosol products with and without nano. Both can pose a hazard if used indoors in unventilated spaces. Hence, the use of spray products should in general be used outdoors or in ventilated rooms.
