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] Coconuts grow on the cocos nucifera, or coconut palm tree. Coconut palms 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 everything from food and drink to fibers, building materials, and natural ingredients.[5,6] Taurine occurs naturally in the animal kingdom. A 154-pound human contains about 2.5 ounces of the substance.[7]

What Does Sodium methyl cocoyl taurate Do in Our products?

Sodium methyl cocoyl taurate is a surfactant that allows water and oil to mix, allowing things to become clean. It also acts as a foaming agent. It 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]

Why Puracy Uses Sodium methyl cocoyl taurate

We use sodium methyl cocoyl taurate as a surfactant and cleanser; it is a good alternative to harsh silicones. The Cosmetics Ingredient Review has deemed the ingredient safe for use in cosmetic products when formulated to be nonirritating.[11] Whole Foods has deemed the ingredient acceptable in its body care quality standards.[12] Research shows the ingredient is typically not a skin irritant or sensitizer.[13,14,15,16]

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. Typically, this means heating coconut acid, sodium methyltaurate solution and boric acid to 200 degrees Celsius while stirring with a subsurface nitrogen purge. This distills off water. The stirring then occurs under lower heat and lower pressure. It is 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 dropped into the solution and stirred. 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]
