Source and Preparation.—Soaps in general are the sodium or potassium salts of the higher fatty acids (lauric, ... Commercial soaps are broadly classed as hard soaps and soft soaps. As a rule, sodium soaps are hard soaps, while potassium soaps are soft. The nature of the higher fatty acid with which the alkali is combined,

Also, at the same time, the sodium (or the potassium) and the fatty acids combine, ... Soaps have been divided into 2 classes: "soft" soaps -- made with potassium hydroxide; and "hard" soaps -- made with sodium hydroxide. But in actuality the initial product obtained by saponifying fats with one or the other of these...

Until quite recently, all soap was a soluble sodium or potassium salt of a long-chain hydrocarbon (fatty) acid, ... Fine soaps were made from olive oil or other high-quality fats. More recently, cottonseed oil, coconut oil, and palm oil have been used. The associated fatty acids have the formulas H3C(CH2)nCOOH. If n = 10,

Triglycerids and Fatty Acids ... Both sodium and potassium oxidize with great rapidity when exposed to the air, and hence are never found in nature except in the form of their compounds.) Hard soaps are sodium salts; soft soaps, potassium salts. The fatty-acid salts of ammonium are also sometimes used for cleansing.

This gives carboxylic acid salts (soap) and glycerol. I'm wondering: Why should the potassium salts of fatty acids yield soft soaps? (A soft soap is one that is very soluble. Also, a salt of a saturated long-chain acid makes a harder, more insoluble soap, but I'm not sure if that has anything to do with it.) ;

Potassium salts of fatty acids should yield soft soaps because they are more soluble in water than sodium salts of fatty acids (which yield hard soaps). They contain more water, so they are softer.
