Of course, in my house, we use environmentally sound products, so I
wouldn't
worry either way. 
The solution to pollution is dilution, so get diluting.
It is my understanding that enviormentally friendly detergents have a low
phosphate content, chlorine free, other things like lack of perfume or
artificial colors are fringe benefits. I bet a 1/2 cup of your product in
the pond would be just as damaging, you just wouldn't get the phosphate
induced algae bloom afterwards.
