Subject: Would biolgical washing powders be better at removing stuborn stains

would they be better than non-biolgical washing powders. It is for research for 
an extended investigation in biology.
thanks


Im doing an investigation into whether enzymes in washing powders,
biological, are better at removing stains than washing powders that don't
contain enzymes, non-biological.
So far my investigation has shown no difference in the removal of stains
between biological and non-biological.
I would have thought that biological washing powders would have removed
stains better because of the enzymes, but I don't know why.
I would be grateful if you could help me understand why this is.
Thanks for you time
