Core Properties

1. Superior Cationic AdsorptionThe positively charged quaternary ammonium groups in its molecular structure exhibit strong affinity for negatively charged substrates such as hair cuticles, skin, and textile fibers. It can adsorb firmly onto these surfaces to form a smooth, breathable protective film, and this adsorption is not easily washed off, ensuring long-lasting functional effects.
2. Outstanding Conditioning and Antistatic EffectsThe long behenoyl chain (C22) aligns closely on the surface of hair and fibers, significantly reducing friction between hair strands or fiber interfaces. For hair care products, it effectively improves dry and wet combability, eliminates static electricity, reduces frizz, and leaves hair soft, glossy, and manageable. For textiles, it imparts a full, smooth hand feel and enhances the antistatic performance of fabrics.
3. Low Irritation and BiocompatibilityCompared with short-chain or medium-chain cationic surfactants, its long-chain structure reduces skin and scalp irritation, making it suitable for formulations targeting sensitive skin and baby care products. It meets the safety standards of cosmetic-grade raw materials and can be used in high-end personal care products.
4. Good Stability and Formulation CompatibilityIt maintains stable performance in a wide pH range (5.0–8.0) and has good resistance to electrolytes. It blends well with non-ionic and amphoteric surfactants commonly used in cosmetics and textiles, but direct mixing with anionic surfactants should be avoided to prevent ionic precipitation and loss of efficacy. It also has good heat resistance and does not decompose easily during normal processing and storage.

Main Application Fields

1. Personal Care and Cosmetics Industry

• Conditioners and Hair Masks: As a core conditioning ingredient, it is added to rinse-off and leave-in conditioners, as well as hair masks, to repair damaged hair cuticles caused by perming, dyeing, and heat styling. It forms a protective film on the hair surface, locks in moisture, and improves hair's resistance to external damage, with recommended addition concentrations ranging from 0.5% to 2.0%.
• Hair Styling Products: Incorporated into hair serums, styling creams, and leave-in treatments, it provides long-lasting antistatic effects, prevents hair from tangling due to static electricity, and helps maintain the stability of hairstyles without causing greasiness or stiffness.
• Skin Care Products: Used in moisturizing lotions, body creams, and sensitive skin care products, it enhances the smoothness of the skin surface, forms a breathable moisture-locking film, and relieves skin dryness and tightness, with a recommended dosage of 0.2% to 1.0%.

2. Textile and Leather Industry

• Textile Softening Finishing Agent: It is widely used in the finishing process of high-grade fabrics such as cotton, wool, silk, and synthetic fibers. It adsorbs onto the fiber surface to reduce friction between fibers, imparting a soft, smooth, and elastic hand feel to the fabrics, while improving their antistatic performance and drapability. It is particularly suitable for the finishing of functional textiles that require long-lasting softness.
• Leather Finishing Agent: Applied in the fatliquoring and finishing stages of leather processing, it helps emulsify leather oils and waxes, allowing them to penetrate into the leather fibers evenly. It improves the softness and flexibility of leather, enhances the surface gloss of leather products, and prevents leather from cracking or hardening during storage.

Storage and Usage Notes

1. Storage ConditionsStore behenoyloxy PG-trimethyl ammonium chloride in sealed plastic or stainless steel containers, placed in a cool, dry, and well-ventilated warehouse. Avoid direct sunlight and high temperatures (storage temperature should not exceed 40°C) to prevent the product from caking or decomposing. Keep it away from anionic surfactants and strong oxidants to avoid chemical reactions. Under proper storage conditions, its shelf life is generally 24 months.
2. Usage Precautions
   • For optimal dispersibility, heat the product to 60–70°C and stir it slowly into hot water or surfactant systems until fully dispersed; avoid adding it directly to cold water to prevent clumping.
   • During industrial handling, wear protective gloves and goggles to avoid direct contact with the skin and eyes. If accidental contact occurs, rinse the affected area thoroughly with clean water.
   • The product has low aquatic toxicity, but direct discharge of waste materials into water bodies should be avoided to comply with environmental protection regulations.
