No,
Nothing more than "Wisk" or whatever detergent,just packaged in larger sizes for commercial and or industry use. One can find all and sundry "domestic" detergents on both sides of the pond sold this way. Tide, Ariel, Persil, and so forth.
One can sometimes find these large sized containers at wharehouse stores such as Costco or Sam's Club. Indeed our local laundrymat purchases their "commercial" sized boxes of Tide at his local Sam's Club.
Has been years since one used liquid Wisk detergent, so cannot remember how well it performed and or if it was highly sudsing (if you own a front loader). I would make sure it is what you want if you order though, a case of four bottles is quite allot of detergent to have lying about spare.
