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 and drink to fibers, building materials, and natural ingredients.[6,7]

What Does Lauramine oxide Do in Our products?

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]

Why Puracy Uses Lauramine oxide

We use lauramine oxide as a surfactant and cleanser. 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]

How Lauramine oxide Is Made

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