In March 2020 Avon Products website was viewed for the company's nanotechnology policy.
The policy stated:
Avon uses a limited number of ingredients characterized as nanomaterials, each with an average particle size of less than 100 nanometres. These are primarily titanium dioxide or zinc oxide, which are used in a wide range of cosmetic products to provide protection against the ultraviolet (UV) rays of the sun...
The safety of each of the ingredients characterized as a nanomaterial currently used by Avon has been individually and fully evaluated by our scientists before being permitted for use in cosmetic products. Avon's evaluation included a specific assessment of the potential for nano-sized particles of these materials to be absorbed through the skin. We will continue to closely monitor the scientific literature on nano-particles and, if we determine that a particular ingredient can no longer be considered to be used safely, we will discontinue its use."
As nanotechnology was considered by some campaigners to pose a significant threat to the environment and human safety, the company received a mark against it in the Controversial Technologies category.
