Non-Biological detergents & Colour detergents...

Methinks the reason so many complain liquid detergents do not remove stains as well as TOL or MOL powders is the absence of bleaches.

Loading detergent with tons of OBAs, surfactants, soaps and enzymes will only get you so far. However some stains simply will not shift totally without some sort of bleach.

Persil = PERborate and SILicate

I think they've changed the formula nowadays because perborate is considered equally harmful to the environment as are phosphates so probably it is percarbonate in it. I will ask Henkel, the manufacturer of German Persil...

Enzymes

Typical enzymes used in detergents include:

Amylase: effective against starchy stains, e.g. mashed potato.
Cellulase: cleans cotton by stripping away loose fibres; supposed to prevent bobbling.
Lipase: breaks down greasy, oily stains, e.g. sebum, vegetable fats and oils.
Protease: original enzyme, effectively breaks down protein stains: blood, gravy, egg.
Mannanase: supposed to be effective against guar gum an associated gums.
Glycosidase: used in P&G biological detergents. Effective against fruit stains, apparently can be tailored to attack certain stain types: now used instead of amylase.

Henkel Persil

Long ago switched to sodium percarbonate. The nearly eight or more years old boxes of Persil Sensitive "megapearls" list sodium percarbonate instead of sodium perborate. Not sure if the formula still contains bleaching activator (TAED) or not.

Borates supposedly are bad for aquatic life and have been on the EU's hit list for awhile now. *Think* a directive was passed to limit or ban the stuff within those borders.

So...

TAED is in it and many enzymes. Also maybe EDTA, I'm unsure of this etidronic acid salt...
