Homemade Detergent Comparison

LC • FTM Due Oct 18th!!!
Has anyone here done (and documented) a comparison between different homemade detergents for cloth diapers? 
 
I'm a little overwhelmed with all the conflicting information about ingredients to use (or not use) in a cloth diaper safe detergent and would love to read/see actual tests done on the cleaning efficiency of some homemade laundry detergent recipes. 
 
Do any of you have suggestions for what recipe has worked for you? I'm afraid of my cloth diapers losing their absorbency if I use the wrong ingredients!!
