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

Product Overview

Guar Hydroxypropyltrimonium Chloride is supplied as a conditioning polymer for cosmetic and personal care formulation use. This material is identified under CAS 65497-29-2 and is also referenced as cationic guar, guar hydroxypropyltrimethylammonium chloride, and guar gum hydroxypropyltrimonium chloride.

As a polymeric reaction product, Guar Hydroxypropyltrimonium Chloride has no single molecular formula; grade selection depends on viscosity and cationic substitution as well as hydration behaviour.

Product Information / Specifications

Quality Control for Cationic Guar

Compare Guar Hydroxypropyltrimonium Chloride grades using matched viscosity test conditions: polymer concentration, hydration time, temperature, viscometer type, spindle and speed. Review moisture, particle size, solution pH and microbiological limits alongside the stated cationic substitution or charge-density data. A viscosity number alone does not establish equal conditioning or deposition performance. We can provide viscosity test conditions and grade-specific quality information for purchasing comparisons.

Physical & Chemical Properties

• Solubility: Hydrates or disperses in water; solution clarity and viscosity depend on the selected grade and formulation conditions.
• pH: Cationic guar solution pH is reported with the polymer concentration, temperature and test method.
• Odor: Odorless or with a slight characteristic odor.
• Stability: Follow the supplied SDS and grade-specific storage conditions; keep the package closed and protected from moisture.

Applications

Guar Hydroxypropyltrimonium Chloride is commonly applied as a conditioning and deposition polymer in personal care systems.

• Shampoo formulations
• Conditioners and hair masks
• Facial cleansers, shower gels, and related mild cleansing systems
• Selected rinse-off and leave-on personal-care formulations after grade and formulation compatibility review

For conditioning-polymer selection, compare Polyquaternium-10 (PQ-10) and cationic guar grades listed under CAS 71329-50-5 against the intended shampoo or conditioner. PQ-10 has a cellulose backbone, while guar derivatives can differ in their modification profile. Check the exact INCI, charge characteristics, hydration and finished-formula performance; related conditioning applications do not make these materials identical or interchangeable at the same dosage.

Hydroxyethyl Cellulose (HEC) can be considered as a nonionic rheology modifier alongside cationic guar in suitable personal-care formulations. Select a grade appropriate for cosmetic use and verify hydration, viscosity and compatibility in the complete system. HEC is not a synonym for Guar Hydroxypropyltrimonium Chloride and should not be assumed to provide the same cationic conditioning or deposition function.

Packaging

We specify moisture-protective packaging for the selected cationic guar grade in our quotation, according to quantity and destination.

Storage Conditions

Store in a cool, dry place and keep the package tightly sealed. Avoid exposure to high temperature and high humidity during storage.

Moisture protection is recommended to help maintain handling and formulation performance.

Safety Precautions

Handle according to the supplied SDS and workplace controls; minimize dust and avoid direct eye or skin contact.

Use appropriate protective equipment such as gloves and eye protection when handling cationic guar. We can provide COA, TDS and SDS for the supplied grade.
