Looking at my own 6 lb tub of Oxi Clean it's hard to say what this stuff is. I can glean there are no phosphates, it's chlorine free and made of organic materials. Here is a link that might help
http://greatcleaners.protocolusa.com...e.asp?abbr=OXI and interestingly, the home page says something about great cleaners do grow on trees. As for a personal testimonial, I have had no big sucess story to report. My dh adds it to the homemade laundry detergent

: altho the dog barf he cleaned up with it left no trace, and the one I did with hot soapy water and a carpet sucker is visible...Don't worry, the dog is getting better with the help of herbals...
