Must list hazardous ingredients, and for some reason enzymes are considered in that category. Thus when included in laundry products they normally are listed. At least have always seen them included on all such sheets for laundry products that contained.
Many middle and lower shelf laundry detergents don't contain a single enzyme. Some only one (usually protease).
OTOH in world of commercial and industrial laundry detergents many are formulated without enzymes. Such places still rely more upon chemicals, moderate to high pH levels, and hot to very water along with good mechanical action to deal with soils/stains. What isn't removed by detergent alone will be handled by extensive use of chlorine or other bleaches.
Part of this has to do with short wash cycles in commercial/industrial laundries. In such settings wash times are between 6-8 minutes only on average. If soil is heavy there might be a second suds for same amount of time. Usually such short wash times don't give enzymes time to work properly. So a laundry must decide if the added length of time (which ties up a machine) is worth results.
Speed Queen washers at local laundromat complete a full "Normal" cycle in about 30 minutes. The pre-wash is barely two minutes long, main wash about 8-12 minutes (you can pay extra 25 cents for two minutes extra time), then onto three rinses then extract. That just isn't enough time for enzyme detergents to work.
This is reason you see so many tubs of Member's Mark or similar powdered detergents in rubbish of laundromats that offer wash and fold service and other such places.
