Ooh good topic here.
1. Calgonite--apparently is still available in Canada. A "dollar/salvage" store around here (Detroit) sells it--a Benckiser (Electra-Sol) product I think. It's labeled as "low-phosphate"--I guess it's just an old-skool non-enzyme dishwasher detergent.
2. My family was big into the detergent business--my grandfather was a chemist who did some early work on surfactants for a soap company in Cincinnati (not P&G) right after WW2--he'd take home samples of early detergents for my grandmother to try. She'd show the other ladies as they "did the dishes" after a dinner party the wonders of these new detergents. Of course they'd marvel at it!
She said as she was remembering that they hadn't really gotten the fragrance working very well and that the detergent worked great but smelled like a public washroom
3. My dad worked for Monsanto (that grandfather got him the job back in 1962) and so my mom often used All (by that time they'd sold the business to Unilever) but the more interesting thing was going with my dad in the family Valiant to Robins Chemical in downtown St. Louis to pick up 25# bags of their commercial laundry detergent--I seem to recall it was called "Sterox" (rich in Monsanto tripolyphosphate!) for her and the neighbors (she'd take orders from all the neighbors). She'd dump it into a barrel next to the washing machine (1963 Kenmore 70 in coppertone) and dose it out with her Kenmore poly measuring cup
4. When I was between jobs in 1992 I got some contract work for Monsanto to research EPA filings for areas around their phosphate plant in Columbia, Tenn and some of their competitors in Pennsylvania, Illinois and others.
5. My roommate in college's mom was a water plant operator on Lake Erie. I was a business major, he was geology, and we'd get into debates over whether you could use phosphates in detergent or not. I actually would bring detergent from home where you could use phosphates (btw when Fresh Start still had phosphates...that detergent rocked) but he was committed to non-eutrophication
Tks for the memories!
