German consumer magazine Test found out in their take on fabric softenes which was called "Cuddling Up With Surfactants" that while improving wrinkling and ease of ironing most FS faded colors faster and even accelerated pilling of fibers than compared to repeated washings without FS.
What a contrary to marketing and advertising this is...
So I wouldn`t count too much on the claimed benefits of this Downy product.
The active ingredient in Downy Defy Damage Dialkylester Dimethyl Ammonium Methosulfate seems to be an ester quart or in other words a cationic surfactant just like Diethylester Dimethyl Ammonium Chloride which is the softener in liquid Downy versions.
I wonder what`s the difference between those two as we all know that FS and detergent should not be mixed because they cancel each other out.
Maybe you gain some fabric care by losing activity of the detergent, but wouldn`t just using less detergent have a similar effect at no extra cost?
