What Is Caprylhydroxamic acid?
Caprylhydroxamic acid, also called octanohydroxamic acid, is a white or tan solid derived from coconut.[1,2] Coconuts grow on the cocos nucifera, or coconut palm tree, around the world in lowland tropical and subtropical areas.[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]
What Does Caprylhydroxamic acid Do in Our products?
Caprylhydroxamic acid is a preservative that ensures products stay fresh while on the shelf and in your home. The ingredient is commonly found in conditioner, shampoo, and other items.[7]
Why Puracy Uses Caprylhydroxamic acid
We use caprylhydroxamic acid in several of our products as a biodegradable preservative that is a better alternative to parabens, isothiazolinones, and formaldehyde.[9] Whole Foods has deemed the ingredient acceptable in its body care quality standards, and research shows the ingredient is not a strong skin irritant or sensitizer.[10,11, 12]
How Caprylhydroxamic acid Is Made
Caprylhydroxamic acid production starts by reacting hydroxylamine hydrochloride with an alcohol solution, N-octoate, and 4-Dimethyl Aminopyridine. The mixture is heated, then cooled, filtered and crystallized.[8]
