Guar Hydroxyproyltrimonium Chloride ●
TL;DR. This ingredient is a cationic conditioning polymer used mainly in shampoos, conditioners, and body washes to improve slip, detangling, combability, and soft feel after rinsing.
What does Guar Hydroxyproyltrimonium Chloride do in a cosmetic formula?
This ingredient is a cationic conditioning polymer used mainly in shampoos, conditioners, and body washes to improve slip, detangling, combability, and soft feel after rinsing.
Is Guar Hydroxyproyltrimonium Chloride clean?
Clean-beauty frameworks generally view it as acceptable and well tolerated at typical low use levels. The main quality watchpoint is residual quaternizing reagents from manufacturing, which reputable suppliers control by specification.
Is Guar Hydroxyproyltrimonium Chloride sustainable?
This material is usually made from a renewable seed-gum polysaccharide, then chemically modified to add conditioning charge. It is generally considered biodegradable, although its cationic nature means it can bind to wastewater solids during treatment.
Is Guar Hydroxyproyltrimonium Chloride COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when the raw material meets the standard’s derivation and processing requirements. Its renewable backbone and biodegradability support Green Chemistry alignment, while the synthetic modification step makes it less simple than an unmodified botanical gum.
How does Guar Hydroxyproyltrimonium Chloride work chemically?
The molecule is a high-molecular-weight galactomannan backbone bearing cationic hydroxypropyl trialkylammonium groups with it counterions, which helps it adsorb to negatively charged hair and skin surfaces. Typical use is about 0.1% to 0.5% active in rinse-off systems, with good performance across mildly acidic to neutral pH and useful coacervate formation with anionic surfactants.
