Guar Hydroxypropyltrimonium Chloride ●
TL;DR. This ingredient is a cationic conditioning polymer used to improve wet combing, softness, and slip in shampoos, conditioners, and body washes. It also helps reduce static and can add a light, cushiony feel to rinse-off formulas.
What does Guar Hydroxypropyltrimonium Chloride do in a cosmetic formula?
This ingredient is a cationic conditioning polymer used to improve wet combing, softness, and slip in shampoos, conditioners, and body washes. It also helps reduce static and can add a light, cushiony feel to rinse-off formulas.
Is Guar Hydroxypropyltrimonium Chloride clean?
From a clean-beauty perspective, it is generally well tolerated and has strong acceptance in sulfate-free and naturally positioned hair care. The main quality considerations are residual quaternizing reagents or byproducts, which reputable suppliers control through specifications.
Is Guar Hydroxypropyltrimonium Chloride sustainable?
This material is based on a plant-derived seed gum that is chemically modified to improve hair substantivity. It is generally considered biodegradable, with a better environmental profile than many fully synthetic conditioning polymers.
Is Guar Hydroxypropyltrimonium Chloride COSMOS-approved?
It is permitted in COSMOS-natural and COSMOS-organic formulations when made through compliant chemistry and supplied with the right documentation. Its renewable backbone, low use levels, and biodegradability fit Green Chemistry goals, although the cationic modification adds some processing complexity.
How does Guar Hydroxypropyltrimonium Chloride work chemically?
The molecule is a galactomannan polysaccharide backbone bearing hydroxypropyl and quaternary ammonium substituents, which gives it positive charge and strong attraction to negatively charged hair and skin surfaces. Typical use levels are about 0.1% to 0.5% in rinse-off hair care, and it is usually dispersed before full hydration to prevent clumping.
