Speaking of Detergent's across the border
P&G has not completely eliminated Phosphates from their Ariel Production. They have begun to phase it out from some markets (like Columbia) but for Peru & Mexico -- they are still making the Ariel Powder with Sodium TripolyPhosphate.
What is, however, interesting, is they have completely removed Phosphates from "Ace"... their Tide brand, in Latin America. And they proudly boost "No Sin FosFatos" . On many of the new bags of Ariel you'll even a "Biodegradable" seal, but with an assterisk noting that only the surfactants & enzymes are truly "Biodegradable".
Foca & Roma can still be found in many stores in Mexico containing Phosphates. The company Lacorona still produces two versions for sale in North & Latin America. Many of you have probably seen the US Verison formulated with Zeolite, but the Latin version generally has 30 - 35 % STPP by Weight, and the FOCA can be a strong performer. Same with the Ariel Doble Poder (translates as Double Power) in sold in Mexico, still containing Phosphate.
Lastly. I've personally found that the Latin American (Mexico) version of Ariel + Downy Powder (Polvo) is much lower sudsing than before, and they appear to have added suds suppressors into the formula. I can now, safely use a dose of 1/3 a cup, or 1/2 a cup with minimal suds and clear rinses. Versus the two tablespoons, I originally dosed years ago.
