In February 2020, Ethical Consumer received a completed questionnaire from Beiersdorf. It contained a response to a question on the company's use of nanoparticles.
"Beiersdorf uses the Nano pigments titanium dioxide and zinc oxide as highly effective mineral UV filters in several sun protection products because they reflect the harmful UV radiation of sunlight."
Ethical Consumer considered nanotechnology to be a technology that carried potential environmental and health risks, and had not yet been
sufficiently established as safe. The company lost half a mark in the Controversial Technologies subcategory.
