Currently lots of German ecological stores and supermarkets sell soap nuts from soap nut trees.
The hazel nut shaped fruits of this tree are rich in saponine and are apparently not only good for washing your clothes but it is also recommended for washing pets because it is said to be very gentle to the skin and to be free from additives.
I have not tried it out myself but I have a sample of the soap nuts at home.
