UV-Filter and antioxidants
Proctection for humans and products
One use of UV-Filter substances is to protect the human skin from high-energy UV-radiation. However in many products the main use is protecting the product. There is a broad range of uses for UV-filters: in plastics and paints, filters are used to prohibit fragility and discolouring; in food they are used to prohibit spoilage.
Similarly antioxidants are often used for preventing product spoilage although, like vitamin E, some antioxidants are highly valuable for nutrition.
The filter substances can leach from the product and enter the environment.
