Description

Poly(oxy-1,2-ethanediyl), .alpha.-hydro-.omega.-hydroxy-, ether with N-2-bis(2-hydroxyethyl)methylammonioethyl-N,N-bis(hydroxyethyl)-N,N-dimethyl-N-octadecyl-1,2-ethanediaminium tris(methyl sulfate) (4:1) (salt) is a high-performance, multi-functional cationic surfactant and antistatic agent. Its complex molecular structure, featuring a long alkyl chain and multiple quaternary ammonium groups, provides exceptional surface activity and compatibility in demanding formulations. This compound is essential for manufacturers in the personal care, textile, and specialty chemical industries seeking to enhance product performance, stability, and feel.

Application

• Hair Care Formulations: Acts as a highly effective conditioning agent and antistatic in shampoos, conditioners, and hair masks, providing superior detangling and softness.
• Fabric Softeners & Textile Auxiliaries: Imparts a soft, smooth hand feel to fabrics and functions as a durable antistatic agent in textile finishing processes.
• Personal Care Products: Used in skin creams, lotions, and shaving gels as an emulsifier and conditioning agent that improves skin feel and product spreadability.
• Industrial Surfactant Blends: Serves as a key component in specialty surfactant mixtures for industrial cleaning, emulsion polymerization, and as a processing aid.
• Antistatic Coatings: Formulated into coatings for plastics and synthetic fibers to prevent static charge accumulation.

Quality Control

Our production of this specialty cationic surfactant adheres to rigorous quality testing protocols to ensure batch-to-batch consistency and performance. While specific grades can be tailored, standard quality parameters include assay/purity, identification, and critical physical properties. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

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 performance.
