Fatty acid - Wikipedia

In chemistry, particularly in biochemistry, a fatty acid is a carboxylic acid with a long aliphatic chain, which is either saturated or unsaturated. Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, from 4 to 28.[1] Fatty acids are usually not found in organisms, but instead as three main classes ...

How Saponification Makes Soap

Long chain fatty acids have a low saponification value because they contain fewer carboxylic acid functional groups per molecule than short chain fatty acids. The sap value is calculated for potassium hydroxide, so for soap made using sodium hydroxide, its value must be divided by 1.403, which is the ratio between the KOH and NaOH molecular weights.

Soaps and Saponification Chemistry Tutorial

Most soaps are made from vegetable oils such as olive oil, palm oil and coconut oil. Some soaps are made from animal fats (tallows). Potassium soaps tend to be softer and more water-soluble than the corresponding sodium soap. Soaps from unsaturated fatty acids are softer than those from saturated fatty acids.

How Soap Works

These fatty acids are less soluble than the sodium or potassium salts and form a precipitate or soap scum. Because of this, soaps are ineffective in acidic water. Also, soaps form insoluble salts in hard water, such as water containing magnesium, calcium, or
