I recently noticed that all of the Method line has gone "HE compatable", including their baby detergent. I also noticed that most of the Seventh Generation line is HE, including baby. I have not tried either of these though. I've used the regular HE Method, in the past, and found it acceptable. I use many of their other products with success.
A while back when I called Unilever about the amount of OBA's in All HE, the customer service person told me that the line of All products is low sudsing and could be used in a front load, regardless of designation. My machine will over suds if you look at it wrong, so I haven't tested this.
I'm currently experimenting with Ecover liquid on my darks, because of the lack of OBA's and so far like it, it's very lightly scented. I've only done a few loads with it though. Ecover powder is unscented, not as effective as Tide, etc. but on most things works fine. Hope this helps, Todd
