Like most of us here have a pretty decent sized detergent stash, thus able to play around with various products and examine results. Old school detergents, basically from soap to detergents up until around the 1970's or so depended mainly on somewhat high alkaline levels (washing soda and or borax, phosphates), along with various surfactants ranging from petrol (Naptha and so forth),to modern "eco-friendly" versions. All and all the process simply was to remove dirt, oils and muck, keep them suspended in wash water, then drained away. Then came enzymes.
Enzymes have been a boon to laundry detergents as they allowed for a wider range of stain/soil removal, at lower wash temps, and more important for textile life and skin comfort, not nearly so alkaline levels as before. Commercial laundries seem to have been early adopters of these products, and indeed much of today's laundry detergent chemistry seems to have filtered down from top shelf commercial products. For a commercial laundry, using a neutral or near neutral pH detergent (as most enzyme based are), means souring can be skipped, which means one less step, less water used thus savings.
When using an old school product like the Ecolab in my stash on say bed linens or towels, one really has to crank up the temp to remove the oils and muck, which are merely suspended in wash water. While the laundry is "clean", to my nose a good enzyme based detergent does a better job a removing body oils and their odors than just a plain "detergent". Laundry just seems to smell "fresher", and since can lower the wash temp to 100F or 120F, there is less wrinkling and other problems associated with high temp washes.
Thoughts?
