Punch was introduced in 1968 or so as Colgate's enzyme detergent offering. P&G started the whole enzyme thing with the introduction of Gain in 1966, then added enzymes to Tide as Tide XK in 1967-68, so Lever followed with Drive and Colgate followed with Punch. Then within a year, each of the big three added enzymes to their mainstream detergents. P&G added enzymes to Bold, Oxydol and Dash (but not Cheer, Bonus or Duz. I recall that Lever's only enzyme offering was Drive - none of their other brands (All, Wisk, Rinso, Breeze, Silver Dust, Cold Water Surf) had them. Colgate added "active enzymes" to Fab, Ajax now had "en-jax" action and Cold Power had enzymes as well. Also, Colgate introduced a concentrated powder in 1968 as well - Burst. Even sleepy little Purex jumped on the bandwagon with Brillo Enzyme Detergent - also not a bad product and great packaging with lots of pink. But Purex was not that well represented on the east coast so we never saw much of that.
With all the phosphate nonsense that began in 1972, enzymes as they existed then were not long for this world. So by 1973 - none of the detergents contained them anymore. In addition to the phosphate controversy, there were issues among workers in the manufacturing facilities of rashes and respiratory ailments from the enzymes. It would be years later before enzymes were added back to detergents.
Punch was around in various incarnations until the early 90's though over time, it became harder and harder to find, ultimately becoming Colgate's value brand and you know that was the death knell for any detergent (as it was for Rinso and Dash. The last box I saw was in a small bodega in the next city. As I recall,Burst didn't last that long either - probably not more than a few years.
As an enzyme detergent, Punch was a good product - mother switched to it in 1969. It cleaned quite well and smelled great - also had "adjusted suds" so no oversudsing.
