"Detergent" is a mixture of chemicals, unlike soap which is saponified fat (want a clean as pure as Ivory, gotta be 99.44% pure PIGFAT reacted with lye, yielding sodium tallowate, they always leave that part of the "purity" off though!). Soap "lubricates-off" dirt whereas detergency relies on ionic interactions attributed to the selection of materials going into the "bath" to attract the dirt and transport it, reduce it.
After moving to Asheville, I found that practically no detergent was useful due to the ultra-softened urban hard-water, which has low potential for ion exchange shown by its weird "not washing stuff off" characteristics. This meant that nothing got cleaned, and dishes got "dirtier" for being washed! What gives?
Having a new baby helped push me along, for I wanted no scent (mountain fresh!), or free-radicals...just truly fresh clean clothes and clean dishes. Research showed that commercial detergents, like Tide, are "watered down" to about 50% strength with either, ahem, water for liquid detergent, or calcium carbonate for powdered detergent (chalk, cheaper than dirt and more inert). Even ultra-premium "eco brands" are selling this nonsense...it's called "Greenwashing" in a plastic bottle by "7th Generation" PTUI. The same nonsense is applied to dishwasher formulae: A profit taking move costing 2x more in packing and transportation while halving the effectiveness of the product! Maybe you've had dishes that have the "chalky-scum" or clothes that "itch-ya"?
Considering this, my formulation for detergent is actually quite a bit more economical (4x to 8x @$2/lb) than buying it at the big-box grocery. I know this: when we run out at the homestead, it is a panic situation!
So what is the magic formulation?
Well... our great-great ancestors relied on pretty much two ingredients: Soda ash (fire ashes from vegetation)--- and Pigfat-soap "slivers". Soda ash was formerly known as "warshin soda" and is simply sodium carbonate. The soda was mixed with slivers from a large soap bar, and often salt, urine or bicarbonate. Guess what? These formulations are excellent cleansers.
I use just 3 primary chemicals and one soap in a variable ratio:
non-sudsing (dishwasher)
-----------------------
Sodium carbonate (ion exchange) = ~50%
Sodium sulfate (buffer) = ~25%
Sodium percarbonate (*high power oxidizer) = ~25%
-----------------------
sudsing add (clothes washer)
-----------------------
1-3% Cocosulfate (coconut soap)
or
~1% Lauryl Sulfoacetate (coconut soap)

That's it! Try it for yourself. It's easy to mix in a clean 5 gallon bucket, lasts forever and stomps any "premium brand" stuff you're paying way too much for!
*Billy Mays' "Oxiclean" is actually 1/2 watered down sodium percarbonate, the other 1/2 is chalk! The chalk is useless!
