There was a Duz Soap powder in addition to Duz detergent. Duz Soap was around through the 1970s and P&G tried to boost its popularity after all the phosphate nonsense started. In fact it was one of the few major brands you could get for a while in areas where phosphates were banned (like in Suffolk County Long Island). Then everyone introduced no phosphate versions of Tide, Cheer, etc...
Duz detergent on the other hand started as "premium Duz" and had the golden wheat dinnerware (incidentally manufactured by the Homer Laughlin China Co, maker of Fiestaware). By the late 60's, it just became Duz detergent and had glasses and intermittently Wm. Rogers stainless flatware
Silver Dust also alternated between towels and glasses (first the Libbey Wildflower pattern, then as we got nearer to 1970, the "golden haze" sort of amber colored glasses
The "new Dash" NOT a P&G product - they sold the name to some miscellaneous company, kind of like the Solo liquid you find now.
At our house, my mother was pretty much a solid Dash user, although she admittedly thought Tide or Cheer did a better job. But she believed the high suds products would ruin the machine. By the late 60's she had moved over to Bold, All, Ajax and Punch, but once in a while would try something else like Brillo (from Purex). She tried Breeze once or twice, but also thought it a rip off and Cold Power, which she thought didn't clean very well at all.
By the early 70's it was back to Cheer, an occasional box of Fab, Ajax and Drive. Then for the 80's it was mostly Cheer until they changed the fragrance to that awful stench. By then Tide with Bleach was introduced and it was low sudsing, so that was what she used from then on.
I loved the scent of the 1960's Wisk - very clean and pleasant, but wasn't as fond of the scent into the 70's and later.
Some things were just regional brands. For example i don't recall American Family Detergent in the New York area. I believe Cold Power was introduced in the Midwest as a liquid but we never saw that.
One product that I really loved was Clorox detergent powder. I was travelling a lot for business in the 80's so I would bring boxes of it home from wherever I was. Unfortunately that product never made it to national distribution. It just never caught on so was never expanded and was ultimately discontinued. Too bad because it was a great product with a fantastic clean, only slightly sweet scent. I still have two boxes I haven't opened yet - oh well....
