Here, here.
Some people have managed to get the Seventh Generation stuff to work - but I've always lived in regions with hard water. So I've never been one of them.
I used to buy stuff from a food co-op; it came in a 10" cube of a box and was super concentrated. That worked. (It was 'bio-something' - like biokleen but that wasn't it). That is the ONLY 'crunchy' detergent I've ever used.
I've been using the CalBen stuff for a while and that works IF you have adequately heated water. (It didn't work so well in my Duet until I realized that you had always to use 'heavy' soil so it engaged the heater.) It is only so-so in cold water, though, as it is detergent+washing soda -- a fairly old formulation I think. But it DOES work and DOESN'T have optical brighteners. [their bar soap works very well and is..pure soap].
I don't understand the American mania for only washing in cold water. Some things, yes, but not whites, wools (blood heat water works better), or sheets (95C baby!). Stuff doesn't come clean.
Now, I'm no fanatic either; if I wear a shirt, say, and it is not soiled as I only had it on for a couple of hours, and I always wear a t-shirt I will wear it again. So I believe that you wash dirty clothes and when you wash them, you wash them so they are clean. This means detergent, water, and heat.
Like having salt in a fabric, where the salt crystals rip it I cannot help but think that dirt in fabrics shortens their lives. So how environmentally sensitive is it if your clothes don't come clean, they wear out quicker, and you have to buy more? Is heating water and using the washer less of an impact than buying a new garment?
