If Rogers fatliquor is water based then all that is doing any work is the moisture.
The moisture that works prior to fatliquoring is the pH 3.3 Hydrator - that plum up the leather structure and separates the inter-fibrillary spaces.
Since it has no fats and oils, its empty water and when it’s dry again the fiber collapse and stick together - that will stiffen the leather further and when flex will crack.
Yes!
fatliquor5.0 is waterbased micro-emulsion - it means that the oil and fat molecules are encased by water droplets, that’s why you see all these whites like natural fresh milk.
When the fats and oils is hydrogen-bond with the protein fibers (just like magnet, unlike poles attracts) the water breaks free and wicks up.
This water can be squeeze out dry, but where are the oils and fats?
These oils and fats coats these millions of tiny fibril connecting hinges - to lubricate them so that the leather structure as a whole is soft, supple and strengthen for practical use.
This later water from the fatliquor breaks free and contribute its work by bringing out the foreign suspended soil particulates to the leather surface to be either wipe off when damp or erase-off when crispy dry.
Think carefully!
Do not make a mistake!
Not all water is good for leathers - it has to be leather-safe like pH 3.3 for the hydrator and the pH 3 for the rinse.
Leather-Safe first, then you wouldn’t be sorry when comes to sensitive leathers.
Why do most leather fashion garments cleaning instructions state: "DRY CLEAN ONLY"?
