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]
