What Is Guar hydroxypropyltrimonium chloride?

Guar hydroxypropyltrimonium chloride is a white or yellow fine powder derived from guar beans.[1] It is a kind of galactomannan, which is a polysaccharide.[2] The guar bean comes from the guar plant, which is a legume. Major world suppliers include India, Pakistan, and the United States, as well as Australia and Africa. The plant’s bean has a large endosperm, which is the part of the seed that acts as a food store for the developing plant. Much of that endosperm contains galactomannan gum, which forms a viscous gel called guar gum when mixed with cold water.[3]

What Does Guar hydroxypropyltrimonium chloride Do in Our products?

Guar hydroxypropyltrimonium chloride is often used as an anti-static agent and hair or skin conditioner; it also increases viscosity.[4] Guar hydroxypropyltrimonium chloride is also found in hundreds of personal care products, such as shampoo, conditioner, dandruff treatments, styling products, soap, hairspray, and other products.[5,6,7] We use it as a hair detangler.

Why Puracy Uses Guar hydroxypropyltrimonium chloride

We use guar hydroxypropyltrimonium chloride as an alternative to harsh silicones. Whole Foods has deemed the ingredient acceptable in its body care quality standards, and the Cosmetics Ingredient Review has deemed the ingredient safe for use in cosmetic products.[9,10] Research shows the ingredient is not a skin irritant or sensitizer.[11,12]

How Guar hydroxypropyltrimonium chloride Is Made

Guar hydroxypropyltrimonium chloride production starts by milling guar beans to obtain the natural gum. That gum is then purified, filtered, and reacted with epoxides. One method involves converting guar with 3-chloro-2 hystroxyproply trimethyl ammonium chloride.[8]
