What Is Carboxy inulin?

Carboxy inulin is a water softener and pH adjuster derived from chicory root extract. Inulin is a starch found in the roots of many plants, including chicory.[1] The leaves of the chicory plant are sometimes known as endive.[2]

What Does Carboxy inulin Do in Our products?

Carboxy inulin acts as an aid in removing the calcium and magnesium ions that cause hard water.[3] This boosts the cleaning power of our detergents.[4]

Why Puracy Uses Carboxy inulin

We use carboxy inulin as a water softener in several of our products because it temporarily reduces the surface tension of water, creating a sheeting effect and helping make suds and grime rinse away quickly and completely. This reduces the number of mineral deposits left to dry on surfaces, reduces the need to rinse repeatedly to get soap off, and reduces water consumption. Whole Foods has deemed the ingredient acceptable in its body care and cleaning product quality standards.[6,7]

How Carboxy inulin Is Made

Carboxy inulin is commonly produced by glycolytic oxidation of inulin.[5]
