Well do not think any consumer product lists detailed percentages of contents, not even food. Even MSDS only list a range of possibly dangerous ingredients.
As with other products, P&G does show a listing from highest to lowest concentration, which gives pretty good information, it is vastly better than what came before.
Back to those listings for Tide "Free" HE and Tide CW HE liquids.
Both contain soap, (take that Persil and other European detergents boasting about Savon de Marseille and so forth), and are loaded with the same sort if not the same chemicals found in various Ariel (P&G's "Tide" in the UK and elsewhere), including various polymers.
Speaking of polymers, Tide HE "free" liquid contains one to deal with clay soils, versus TCW "free" liquid, which does not.
