What Is Lauramine Oxide?

Lauramine oxide is a clear, pale-yellow, amine oxide liquid derived from coconut.[1,2,3] 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.[4,5]  Widely cultivated, healthy coconut palms produce 50 nuts per year, and the tree can be used to produce everything from food to building materials to natural ingredients.[6,7]

How Lauramine Oxide Is Made

Commercial production of lauramine oxide occurs largely by mixing the amine with 35% hydrogen peroxide at 60ºC. The mixture is heated to 75ºC and sodium sulfite or manganese dioxide are added. The mixture is then filtered to get rid of extra peroxide.[11,12]

What Does Lauramine Oxide Do?

Lauramine oxide is a surfactant, meaning it breaks surface tension in liquids, allowing things to become clean. It is also a foam builder, stabilizer, viscosity enhancer, emollient, and conditioner.[8] It can be found in personal care products such as shampoo, facial cleansers, body wash, sunscreen, and a variety of other products.[9,10]

Is Lauramine Oxide Safe? 

The Cosmetics Ingredient Review has deemed the ingredient safe for use in cosmetic products and in leave-on products (in which the concentration is limited to 3.7%).[13] Research shows the ingredient is typically not a skin or eye irritant.[14,15,16,17,18,19]
