Potassium soap
| Potassium salts of individual fatty acids (examples) |

 |
Potassium soap is a collective name for potassium salts of individual fatty acids or - more often - mixtures of potassium salts of several fatty acids.
Manufacturing
The saponification of natural fats and oils with potassium hydroxide provides mixtures of potassium salts of fatty acids and glycerine . The proportions of the individual fatty acid anions in the mixture of potassium salts depends on the nature and provenance of the triglyceride used as the raw material . A chemically largely uniform potassium soap can be obtained by reacting a largely pure fatty acid with a stoichiometric amount of potassium hydroxide. Examples of such potash soaps are:
- Potassium oleate, the potassium salt of oleic acid , a yellowish semi-solid substance that can be counted among the glue soaps because of the C = C double bond it contains.
- Potassium palmitate, the potassium salt of palmitic acid (hexadecanoic acid), a white, fatty mass.
- Potassium stearate, the potassium salt of stearic acid (octadecanoic acid), a white powder or compact pieces.
use
Potassium soaps are used as textile auxiliaries , soft soap components ( hand washing paste or liquid soap ), as well as thickeners in mineral oil- based lubricating greases and as a component of shaving creams .
