Which own-brand manufacturer makes which products?

[MrX]

I was just wondering if anyone knew who makes which supermarket's own brand detergents and softeners.

Main Irish supermarkets:

Tesco (Ireland) appears to be mostly using McBride
Dunnes - Swiss Industries gmbh -Liquids look rather like Henkel Persil.
SuperValu - McBride
Centra - McBride
Eurospar - Unknown seems to be German though.
M&S - McBride

Lidl - Unknown, but the liquids look a bit like German persil, but possibly just a marketing copycat exercise.
Aldi - Unknown

Anyone got further info about any of these products, or know anything about them?
