Germany: sources to buy ingredients for DIY Detergent Powder

Hello,

location: Germany

I would like to make DIY detergent powder. In the end, it should not turn out to be more expensive than ready-made detergent.

Here are the things that I'd like to buy:

1. Pure Laundry Soap Bars
2. Washing Soda
3. Borax
4. Bicarbonate of Soda
5. Tea tree oil

Where can I find these ingredients for a reasonable price? Any supermarkts or online shops?
