what is potassium soap
When the alkali is sodium hydroxide, a sodium soap is formed. Sodium soaps are hard soaps. When the alkali is potassium hydroxide, a potassium soap is formed. Potassium soaps are softer and are found in some liquid hand soaps and shaving creams. The carboxylate end of the soap molecule is attracted to water.It is called the hydrophilic (water-loving) end.oaps. Soaps are water-soluble sodium or potassium salts of fatty acids. Soaps are made from fats and oils, or their fatty acids, by treating them chemically with a strong alkali. First let's examine the composition of fats, oils and alkalis; then we'll review the soapmaking process.
