Description

(Carboxymethyl)Bis(2-Hydroxyethyl)Octadecylammonium Hydroxide is a quaternary ammonium compound (quat) featuring a long alkyl chain and a carboxymethyl functional group, offering a unique combination of cationic and anionic characteristics. This amphoteric structure makes it a highly effective and versatile specialty surfactant and conditioning agent. It is primarily sought after by manufacturers in the personal care, home care, and industrial formulation sectors for its superior emulsifying, antistatic, and softening properties.

Application

• Hair Conditioners & Cream Rinses: Acts as a primary cationic conditioning agent, providing excellent detangling, softness, and manageability to hair.
• Fabric Softeners & Laundry Care: Imparts a soft, fluffy hand feel to textiles and reduces static cling in dryer sheets and liquid softeners.
• Skin Care Emulsions: Functions as an emulsifier and skin-conditioning agent in lotions and creams, enhancing product feel and stability.
• Industrial Surfactant & Emulsifier: Used in specialty formulations requiring a cationic emulsifier for oils, waxes, or silicone-based products.
• Antistatic Agent: Applied in plastics, textiles, and electronics manufacturing to dissipate static charge.
• Corrosion Inhibitor: Utilized in water treatment and metalworking fluids due to its ability to adsorb onto metal surfaces.

Quality Control

Our production of (Carboxymethyl)Bis(2-Hydroxyethyl)Octadecylammonium Hydroxide adheres to stringent quality management protocols. Every batch is analyzed to ensure it meets precise specifications for identity, purity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, residual solvents, and other critical parameters is provided with each shipment to guarantee supply consistency and regulatory compliance for your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture which can affect product quality and handling.
