Applicaton and benefits of Lauric acid

Lauric acid, systematically dodecanoic acid,is a white, crystalline, water-insoluble powder, C12H24O2, a fatty acid occurring as the glyceride in many vegetable fats, especially coconut oil and laurel oil: used chiefly in the manufacture of soaps, detergents, cosmetics, and lauryl alcohol.

Occurrence

Lauric acid, as a component of triglycerides, comprises about half of the fatty-acid content in coconut milk, coconut oil, laurel oil, and palm kernel oil (not to be confused with palm oil),Otherwise, it is relatively uncommon. It is also found in human breast milk (6.2% of total fat), cow's milk (2.9%), and goat's milk (3.1%).

Applicaton and benefits

Like many other fatty acids, lauric acid is inexpensive, has a long shelf-life, is nontoxic, and is safe to handle. It is used mainly for the production of soaps and cosmetics. For these purposes, lauric acid is reacted with sodium hydroxide to give sodium laurate, which is a soap. Most commonly, sodium laurate is obtained by saponification of various oils, such as coconut oil. These precursors give mixtures of sodium laurate and other soaps.

Lauric acid is a precursor to dilauroyl peroxide, a common initator of polymerizations.

Nutritional and medical aspects

Although 95% of medium-chain triglycerides are absorbed through the portal vein, only 25–30% of lauric acid is absorbed through it.

Lauric acid increases total serum lipoproteins more than many other fatty acids, but mostly high-density lipoprotein (HDL). As a result, lauric acid has been characterized as having "a more favorable effect on total HDL than any other fatty acid, either saturated or unsaturated".In general, a lower total/HDL serum lipoprotein ratio correlates with a decrease in atherosclerotic incidence.Nonetheless, an extensive meta-analysis on foods affecting the total LDL/serum lipoprotein ratio found in 2003 that the net effects of lauric acid on coronary artery disease outcomes remained uncertain.A 2016 review of coconut oil (which is nearly half lauric acid) was similarly inconclusive about the effects on cardiovascular disease incidence.
