What makes Woolite *different*?

Okay, I was doing laundry last night and staring at the assorted plastic bottles on the shelf, and I finally started to wonder: What is Woolite that it’s different from your typical laundry detergent?

Maybe this is the same question as the other thread on detergents.

I suspect the main difference in Woolite is that it doesn’t leave a ring like soap, so there’s no free fat, and that it isn’t “harsh”, so there’s no free lye.

It has 1/3 the calories of regular Woo. :D:D
