Interactions of TiO Nanoparticles with Ingredients from Modern Lifestyle Products and Their Effects on Human Skin Cells.

The number of consumer products containing nanoparticles (NPs) experienced a rapid increase during the past decades. However, most studies of nanosafety have been conducted using only pure NPs produced in the laboratory, while the interactions with other ingredients in consumer products have rarely been considered so far. In the present study, we investigated such interactions-with a special focus on modern lifestyle products (MLPs) used by adolescents.
