What Is Sodium Methyl Cocoyl Taurate?

Sodium methyl cocoyl taurate is the salt of the coconut fatty acid amide of N-methyltaurine. It is a soft white paste and is derived from coconut.[1,2]  

Coconut palm trees (cocos nucifera) grow around the world in lowland tropical and subtropical areas where annual precipitation is low.[3,4] Widely cultivated, healthy coconut palms produce 50 nuts per year, and the tree can be used to produce food to fibers, building materials, and natural ingredients.[5,6] 

How Sodium Methyl Cocoyl Taurate Is Made

Sodium methyl cocoyl taurate is made by reacting taurine, N-methyltaurine, or a taurate salt with a coconut fatty acid. (Note: Taurine occurs naturally in the human body[7]). This typically means heating coconut acid, the sodium methyl taurate solution, and boric acid to 200º C while stirring with a subsurface nitrogen purge. This distills off water. Stirring then occurs under lower heat and lower pressure. When cooled, the result is a waxy solid that is ground into a powder.[9] 

Another way to manufacture sodium methyl cocoyl taurate is to dissolve taurine in a mixture of water, isopropyl alcohol, and sodium hydrate. Lauric acid chloride and a sodium hydrate solution are stirred into the solution. Next, hydrochloric acid and a calcium chloride solution are added and stirred. The white substance is then filtered and dried. 

Often, sodium methyl cocoyl taurate is sold as a mixture with sodium chloride and water.[10]

What Does Sodium Methyl Cocoyl Taurate Do?

Sodium methyl cocoyl taurate is a surfactant that allows water and oil to mix, allowing things to become clean. It also acts as a natural foaming agent and is a good alternative to harsh silicones. Sodium methyl cocoyl taurate can be found in hundreds of personal care products such as shampoo, facial cleanser, body wash, acne treatments, toothpaste, hand soap, and other products.[8]
