    Cationic Guar Gum CAS 71329-50-5

    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

    1. 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.
    2. 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.
    3. 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 chemical characteristics define Cationic Guar Gum CAS 71329-50-5 as a conditioning polymer?

      A: Cationic Guar Gum (CAS 71329-50-5) is chemically characterized as a cationically modified galactomannan, specifically Guar hydroxypropyltrimonium chloride, which is supplied as a water-soluble polymer known for its high substantivity to protein substrates.
    • Q:

      Is this ingredient compatible with anionic surfactants in shampoo?

      A: Yes, this material is typically applied in anionic surfactant systems (such as SLES/SLS bases) where it forms a coacervate mechanism that aids in the deposition of conditioning actives upon dilution during rinsing.
