Guar Hydroxypropyltrimonium Chloride is a cationic modified natural polymer derived from guar gum, a polysaccharide extracted from the seeds of the guar plant (Cyamopsis tetragonoloba). The modification process involves reacting guar gum with propylene oxide and trimethylamine, which introduces cationic quaternary ammonium groups onto the polysaccharide backbone. This modification endows the polymer with excellent water solubility, cationic charge density, and compatibility with a wide range of surfactants, while retaining the natural thickening and stabilizing properties of guar gum. At room temperature, it appears as a white to off-white free-flowing powder, which dissolves rapidly in water to form a clear, viscous solution.
Compared with unmodified guar gum, Guar Hydroxypropyltrimonium Chloride has stronger adsorption capacity for negatively charged substrates (such as hair and skin) due to its cationic groups. It also exhibits better salt tolerance and stability in acidic, neutral, and weakly alkaline systems, making it a versatile functional ingredient widely used in personal care, especially hair care products.
Excellent conditioning and moisturizing performanceThe cationic groups of Guar Hydroxypropyltrimonium Chloride can firmly adsorb onto the negatively charged hair cuticles and skin surface, forming a smooth, breathable protective film. This film repairs damaged hair cuticles, reduces friction between hair strands, improves wet and dry combability, eliminates static electricity and frizz, and leaves hair with a natural, healthy luster. For skin, it locks in moisture, enhances skin smoothness and softness, and does not cause a sticky or heavy feeling.
Effective thickening and stabilizing capabilitiesAs a polysaccharide polymer, it has strong thickening properties, which can significantly increase the viscosity of aqueous solutions and surfactant-based formulations at low addition levels. It also acts as a stabilizer, preventing phase separation, sedimentation, or creaming in emulsions, shampoos, and conditioners, thus extending the shelf life of products.
Good compatibility and salt toleranceIt is compatible with anionic, cationic, non-ionic, and amphoteric surfactants, which is a distinct advantage over many other cationic polymers. It also has excellent salt tolerance—its thickening and conditioning effects are not easily affected by the presence of electrolytes (such as sodium chloride) in formulations, ensuring stable performance of products in different environments.
Mild and biodegradableBased on natural guar gum, it is mild, non-irritating, and suitable for sensitive scalp and skin care products. It is readily biodegradable, does not accumulate in the environment, and meets the requirements of green and sustainable cosmetic raw materials.
This is the primary application field of Guar Hydroxypropyltrimonium Chloride, with the most extensive use in hair care products.
- Shampoos: Added as a conditioning and thickening agent, it improves the viscosity of the shampoo system and enhances the foam texture. More importantly, it adsorbs on the hair during washing, reducing the damage of surfactants to the hair and making the hair soft and easy to comb after rinsing, avoiding dryness and tangling. The recommended dosage is 0.2%–1.0%.
- Conditioners and hair masks: Serves as a core conditioning ingredient, working synergistically with other conditioning agents (such as silicone oils and amino acids) to deeply repair dry, damaged, and chemically treated hair (perm and dye hair). It can significantly improve the smoothness and luster of hair, with a recommended dosage of 0.5%–2.0%.
- Leave-in hair products: Used in leave-in conditioners, hair serums, and styling products, it provides long-lasting anti-static and anti-frizz effects, keeping hair neat and manageable throughout the day without causing greasiness. The recommended dosage is 0.1%–0.8%.
- Skin care products: Applied in moisturizing lotions, creams, and body washes, it acts as a thickener and moisturizer, improving the spreadability of products and forming a moisture-locking film on the skin surface to enhance skin hydration. It is suitable for both dry and oily skin formulations, with a recommended dosage of 0.1%–0.5%.
- Textile industry: Used as a textile softener and finishing agent. It adsorbs on the surface of textile fibers, improving the softness, smoothness, and anti-static properties of fabrics, especially suitable for cotton, wool, and blended fabrics. It can also enhance the dyeing uniformity of fabrics, with a recommended dosage of 0.3%–1.5% (based on fabric weight).
- Paper industry: Added to paper coatings and sizing agents to improve the strength, smoothness, and printability of paper. It can also enhance the retention of fillers and pigments in the papermaking process, reducing material loss, with a recommended dosage of 0.1%–0.8%.
- Water treatment: Used as a flocculation aid in wastewater treatment. Its cationic groups neutralize the negative charge of suspended particles in water, promoting particle aggregation and sedimentation, and improving the efficiency of solid-liquid separation, with a recommended dosage of 0.05%–0.3%.
Storage ConditionsStore Guar Hydroxypropyltrimonium Chloride in a sealed container in a cool, dry, well-ventilated area, away from direct sunlight and high humidity. Prevent moisture absorption, as damp powder is prone to agglomeration and reduced solubility. Under proper storage conditions, its shelf life is generally 24–36 months.
Safety InstructionsGuar Hydroxypropyltrimonium Chloride is a non-toxic, non-irritating polymer, not classified as a hazardous chemical. It is safe for use in cosmetics and daily chemical products. During operation, avoid inhaling the powder to prevent respiratory discomfort; if the powder accidentally gets into the eyes, rinse thoroughly with plenty of clean water. It is biodegradable and environmentally friendly, with no adverse impact on aquatic organisms when discharged in compliance with regulations.
