Ohhh yes!
Standard basic laundry powdered detergent used by commercial/industrial and laundromats all over. See empty buckets of it outside local dry cleaners or drop off laundries out for rubbish collection.
Not much different than Arm & Hammer powdered detergent of old. Surfactant ( mostly Alcohols, C12-15, ethoxylated) and washing soda make up bulk of cleaning power. Again typical somewhat high pH detergent. Cheap and usually effective; especially if one uses chlorine bleach to handle stains and multitude of other wash day sins.
Like Arm & Hammer powdered detergent of old this product and similar are heavy on washing soda, something like 60% or more. This explains why they like A&H powder are inexpensive. That in turn is why some commercial/industrial laundries or laundromats love the stuff. They can get several huge buckets for very little money compared to a TOL built detergent like Tide or similar.
There are of course available to industrial/commercial and domestic users a variety of boosters (enzymes, etc...) that can be used along with these sort of detergents if required.
These kinds of powdered detergents can leave things feeling harsh and scratchy; hence use of sours in commercial/industrial setting. Domestic users can always go with adding white vinegar to final rinse.
For those that lead a low soil lifestyle, and or for things like massage sheets, bed linens, etc... things mostly contaminated by body soils this detergent isn't bad. Combine somewhat high pH with plenty of hot water and perhaps chlorine bleach and you'll get decent results.
