Are all Guar Hydroxypropyltrimonium Chloride grades interchangeable?

No. Grades under the same INCI and CAS can differ in cationic charge density, molecular weight or solution viscosity, particle size and hydration behaviour. Compare grade-specific data against the intended surfactant system rather than the label alone.

How can Cationic Guar be added without undispersed particles?

Use the grade’s recommended addition order, introduce the powder slowly under adequate agitation and allow hydration before high salt or surfactant loading. Some grades are self-hydrating while others are designed for controlled hydration, so process conditions must match the grade.

Can Cationic Guar replace Polyquaternium-10 directly?

Not at a like-for-like dosage. Their polymer backbones, charge distribution, hydration and deposition differ. Assess clarity, viscosity, foam, combing and stability in the finished system before making a substitution.

Guar Hydroxypropyltrimonium Chloride (Cationic Guar) CAS 65497-29-2

Guar Hydroxypropyltrimonium Chloride (CAS 65497-29-2, ECHA List no. 613-809-4) is a cationic guar polymer used to improve conditioning, wet combing, deposition and sensory properties in shampoos, conditioners and related personal-care formulations. As a polymeric reaction product, it has no single molecular formula. Viscosity, cationic substitution level, moisture, form and packaging should be confirmed for the supplied grade. COA, TDS and SDS may be provided on request.
