Description

(2-Hydroxytrimethylene)Bis[Dodecyldimethylammonium] Dichloride is a high-purity, synthetic quaternary ammonium compound (quat) with a gemini surfactant structure, offering superior performance over traditional mono-quats. Its dual cationic head groups linked by a hydroxytrimethylene spacer provide enhanced efficacy at lower concentrations, making it a powerful and cost-effective solution for demanding applications. This compound is essential for industries requiring advanced antimicrobial action, surface modification, and phase transfer catalysis.

Application

• Industrial Biocide & Disinfectant: A key active ingredient in formulations for hard surface disinfectants, algicides, and sanitizers for the food processing, healthcare, and water treatment industries.
• Fabric Softener & Textile Auxiliary: Provides excellent softening, antistatic, and dye-leveling properties in textile manufacturing and laundry care products.
• Personal Care Preservative: Used as a preservative and conditioning agent in shampoos, hair conditioners, and other rinse-off cosmetics due to its substantivity to hair and skin.
• Oilfield Chemistry: Acts as a clay stabilizer, corrosion inhibitor, and bactericide in drilling and completion fluids for enhanced oil recovery.
• Paper Manufacturing: Functions as a retention aid, drainage aid, and biocidal agent in paper and pulp processing.
• Phase Transfer Catalyst (PTC): Facilitates reactions between reagents in immiscible phases in organic synthesis for pharmaceuticals and specialty chemicals.

Quality Control

Our (2-Hydroxytrimethylene)Bis[Dodecyldimethylammonium] Dichloride is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and critical impurities are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
