Know one is not crazy and saw STPP in some bar of Mexican soap. If Fels could add washing soda, and Kirkman, borax, then the thing is not too far fetched.
In my research onto the matter, found a very interesting bit of information. Anyone wish to guess just who is behind many Mexican detergents removing phosphates from their formulas? It is not the US government either.
Give up?
Walmart, or Walmex as it is known south of the border.
Turns out once NAFTA was passed, Walmart wasted no time high-tailing it down to Mexico, and importing their high handed ways regarding costs controls and pricing.
Walmart sells quite allot of Mexican laundry products in the United States, and put it to the suppliers that in order to increase their US sales, non-phosphate formulas would be required of detergents and such in order to avoid local state bans.As anyone who knows Walmart can attest, it does not like ordering items for just one area, but orders in bulk for everywhere. Walmex/Walmart made their wishes known, and the results have been felt across Mexico and South America. For one thing it has lead to a consolidation with the detergent industry. The other of course is the cross border marketing of certain laundry products to take advantage of native markets in Mexico, and the growing Hispanic market in the United States.
For instance, besides finding brands such as Ariel, Zote, Suvitel, and such in the United States, one finds there is now a Downy fabric softener sold in Mexico. Who knew?
