How could it be? Two 92 ounce bottles of Tide+ detergent are side by side on store shelves, with one claiming it gets 48 loads and the other says 59 loads.

The cap explains that the bottle on the right above is new and gets 20% more loads per jug.

Don’t even try to decipher the small print under the 20% claim (hint: they used a slash when they should have used a semi-colon).
The secret to how they squeezed more loads into the same size bottle is partially disclosed in fine print on the back.
*MOUSE PRINT:


In small print, we first learn that the number of loads claimed is for “medium” size washing loads, which really appears to be a euphemism for small loads. But by examining the pictures of the caps shown, one learns the other trick of sorts that P&G used to get more loads out of the same size bottle. They changed the dosing. Where previously, filling the cap to line 2 gave you 48 medium loads, they now instruct users just to fill the cap to line one to miraculously get 59 loads — 20% more.
Similarly, the dosing changed for large loads from filling the cap to line 4 previously, to now filling it to only line 3. Curiously, for “full” loads, they still recommend filling the cap to the fifth line. And in so doing, users will achieve no increase in the number of loads at all.
That actual number of large loads per bottle, incidentally, is only a bit more than 21 according to P&G for both the old and new bottles. Twenty-one loads when the front of the bottle promised 48 or 59 loads? Nice. But, unfortunately, this is a game played by all detergent makers — promote the largest number of loads possible based on the smallest amount of clothing to be washed.
We asked P&G whether they accomplished the claimed increase in loads merely by changing the dosing instructions to use less, or whether they changed the formula making it more concentrated. In a series of emails, their PR spokesperson replied in part:
We further concentrated the formulas of Tide Plus Downy, Tide Plus Febreze, Tide Plus Bleach Alternative and Tide Cold Water so that you can use less liquid per dose but maintain the same cleaning power.
For medium and large loads, the new dosing provides 20% more loads per bottle than before.
We rebalanced the formulas we’ve been discussing and we did so in order to 1) continue to provide an outstanding clean and 2) ensure we could continue to provide the added benefits of each formula with the same dose as our “regular†formulas.
We have not changed the recommended dose for HE Full Capacity … [because] 1) these HE washing machines continue to get larger and require more cleaning power for larger loads… and 2) we know most consumers do not dose at HE Full Capacity for “all†loads on a regular basis.
So, it seems like P&G accomplished getting more loads out of the same size bottle by a combination of introducing a more concentrated formula and by recommending using less.
What still remains a mystery is why those fill lines inside the cap are so darn impossible to find and read.
