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.
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. 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.
