Lauric acid, also known as dodecanoic acid, is a saturated fatty acid. Its molecular formula is C12H24O2. Although it is called lauric acid, it only accounts for 1-3% of the content of laurel oil. At present, it is found that vegetable oils with high lauric acid content include coconut oil 45-52%, oil palm seed oil [palmkernel] 44-52%, babassu seed oil [babassukernel] 43-44%, etc.
Lauric acid can be used to produce soap:
One of the main ingredients of soap. A typical amphiphilic molecule has completely different affinities at the head and tail ends. The head of the molecule is a polar gene and is hydrophilic. The tail is a hydrocarbon chain, which is lipophilic. When water, oil, and soap are mixed, the amphipathic molecules automatically assemble into layers. The tails of the molecules point toward the oil and the heads point toward the water.
In low-concentration soap liquid, amphiphilic molecules that are isotropic and randomly distributed form micelles. Add water to dilute the micelles and disappear. Increasing concentration results in the formation of more extended micelles. Resulting in the formation of a series of liquid crystal phases. The cubic and hexagonal phases appear successively with increasing concentration.
Since lauric acid is a saturated fatty acid, it has extremely high stability. Its function in handmade soap is good foaming, high stability, high hardness, and large soap body that is not easy to deform. After being made into soap, it is not easy to produce oil. Spot deterioration
