The gotcha is that enzymes are useless when it comes to removing inorganic soils from fabrics. So an effective detergent still needs some alkali and surfactant to break these away from the fabric, and a builder to capture them so they can be rinsed away. This is where most liquid laundry detergents perform less admirably than powders. The powders are more alkali, and can incorporate more efficient water softeners and breaks than liquids.
And of course STPP is perhaps the best ingredient to break inorganic soil from fabrics, and to hold it in suspension so it can be rinsed away. Nothing else really comes close.
