Apologies, I'm not clear on what you're pointing out in my comment as incorrect. I specified that DEAs are used in products that come from industrialized processes, that you won't find them in home-made products of the same nature.
I'm using "industrialized" to mean "mass-produced" here, as in stuff that comes from a factory rather than a small work station in a DIYer home. I wonder if this may be causing confusion?
The article you linked is likely speaking of mass-produced products, but does not go so far as to specify that (they should). I separate the two since they really are quite different. If you put one of my bars of soap up against Dove, for example, you'll notice that mine do not lather nearly as much a Dove, nor do they have that "buttery" texture of commercial soaps. DIY soaps typically only need lye, distilled water, and olive oil then whatever you want to add for scent. DEA does not enter the equation in a home-made version.
