Cationic Guar Gum (CAS 71329-50-5) is a substantive quaternary ammonium derivative of natural guar gum utilized as a premium conditioning agent in shampoos and body wash formulations. Chemically identified as Guar hydroxypropyltrimonium chloride, this yellowish powder functions to neutralize negative charges on hair strands, providing excellent detangling and anti-static properties without buildup. As a highly compatible Bio-polymer conditioner, it is extensively integrated into "2-in-1" hair care systems to enhance the deposition of silicones and oils onto the hair fiber. We ensure bulk supply capabilities for this material, providing access to competitive factory pricing and customized specifications to meet specific viscosity and degree of substitution requirements. Full technical documentation, including MSDS, TDS, COA, is available to support compliance and safety protocols.

Product Description
Cationic Guar Gum is a water-soluble quaternary ammonium derivative of guar gum. Unlike regular guar gum, the cationic charge allows it to adhere to anionic surfaces like damaged hair and skin.
Key Features:
- Conditioning: Improves wet and dry combability of hair.
- Deposition: Helps deposit active ingredients (like silicones or oils) onto the hair/skin surface (known as the “coacervation” effect).
- Foam Stabilization: Enhances the creaminess and stability of lather in surfactant systems.
- Mildness: Reduces the irritation potential of surfactants on the skin.
It is widely used as a cost-effective alternative to synthetic conditioners and is suitable for clear or opaque formulations.

Applications
- Hair Care:
- Shampoos: Essential for 2-in-1 conditioning shampoos; provides detangling and anti-static effects.
- Conditioners: Improves hair manageability and softness.
- Hair Masks: Repairs damaged hair cuticles.
- Skin Care:
- Body Washes & Shower Gels: Leaves skin feeling soft and moisturized after rinsing; reduces tightness.
- Hand Soaps: Improves the sensory feel of liquid soaps.
- Shaving Creams: Provides slip and lubrication for a smoother shave.
- Usage Level: Typically used at 0.1% to 0.5% in formulations. It should be dispersed in water with agitation and neutralized (if necessary) or added to the surfactant phase depending on the specific formula process.
Storage Conditions
- Environment: Store in a cool, dry, and well-ventilated area.
- Moisture Control: This product is hygroscopic (absorbs moisture). Keep bags/drums tightly sealed when not in use to prevent clumping.
- Temperature: Avoid exposure to excessive heat and direct sunlight.
- Shelf Life: 24 months from the date of manufacture under proper storage.
Safety Precautions
- Slip Hazard: Caution! The powder becomes extremely slippery when wet. Clean up spills immediately with dry methods (sweeping) before washing the area.
- Inhalation: Avoid breathing dust. Use a dust mask (N95 or equivalent) when handling large quantities to prevent respiratory irritation.
- Eye Contact: Flush eyes with plenty of water for at least 15 minutes.
- Skin Contact: Generally safe, but wash with soap and water after bulk handling.
- Fire: Combustible dust. Avoid creating dust clouds near open flames or sparks.
FAQ - Technical & Supply Chain

Q:
What is Cationic Guar Gum CAS 71329-50-5?
A: Cationic Guar Gum CAS 71329-50-5, also known as guar hydroxypropyltrimonium chloride, is a water-soluble quaternary ammonium derivative of natural guar gum. It is used as a conditioning polymer in shampoos, body washes and other personal-care products. -
Q:
How does Cationic Guar Gum condition hair?
A: Its cationic charge attaches to the negatively charged surface of damaged hair, improving wet and dry combability, reducing static and helping deposit conditioning actives such as silicones or oils onto the hair. -
Q:
What is the coacervation effect?
A: During rinsing, cationic guar can form a complex with anionic surfactants in the formula. This coacervate separates from the diluted shampoo and deposits conditioning ingredients onto the hair or skin instead of washing them all away. -
Q:
Can Cationic Guar Gum be used in anionic surfactant systems?
A: Yes. It is designed to be compatible with anionic systems such as SLES and SLS bases. It helps build creamy, stable lather and supports deposition of conditioning actives in 2-in-1 shampoos and rinse-off cleansers. -
Q:
What are the main applications?
A: Cationic Guar Gum is used in conditioning shampoos, hair conditioners, hair masks, body washes, shower gels, liquid hand soaps and shaving creams. It improves softness, slip, detangling and after-rinse skin feel. -
Q:
What is the typical usage level and how should it be dispersed?
A: It is commonly used at 0.1% to 0.5% in formulations, although the exact level depends on the desired conditioning and viscosity. Disperse it in water with agitation and add it to the aqueous or surfactant phase according to the formula. -
Q:
What special handling or storage is required?
A: The powder is hygroscopic and becomes slippery when wet, so keep containers tightly closed and clean dry spills before washing. Store in a cool, dry area away from heat, moisture and direct sunlight; the shelf life is about 24 months.
