Lauric acid or dodekanoat acid is saturated fatty acid chain is (Ing. middle-chained fatty acids, MCFA) which is composed of 12 atoms of C. The main source of these fatty acids are coconut oil, which can contain 50% lauric acid, and palm kernel oil (palm kernel oil). Another source is cow's milk.
Lauric acid has a melting point 44 ° C and a boiling point of 225 ° C so that at room temperature a white solid tangible, and easy to melt when heated. Chemical formula: CH3 (CH2) 10COOH, molecular weight 200.3 g.mol-1. Acid is soluble in polar solvents, such as water, also soluble in fat because hydrocarbon group (methyl) at one end and carboxyl group at the other end. This behavior is utilized by the laundry industry, for example in the shampoo. Sodium laurilsulfat is an instance of the most frequently used in industrial soap and shampoo.
