Addendum:
Unfortunately, I realized that the product strongly irritates with regular use in sensitive areas, and even leads to inflammation! Therefore, only 1 star from me.
In addition, the product contains acrylates copolymer. These are micro spheres of the Kuststoff wiederrum go untreated into the environment and therefore into the food chain. Meanwhile, these polymers are already detected in the milk. A current PlusMinus post of 09.01.2014 can be found under the search term Plastic beads in foods and cosmetics.
