Description

Ethyltris(2-Hydroxypropyl)Ammonium Ethyl Sulphate is a quaternary ammonium compound featuring three 2-hydroxypropyl substituents and an ethyl sulphate counterion, widely employed as a cationic surfactant and phase-transfer catalyst. It delivers exceptional water solubility, low toxicity, and strong surface activity—making it ideal for formulations requiring mild yet effective cationic functionality. This compound is extensively used in specialty polymer synthesis, textile auxiliaries, agrochemical formulation, and personal care emulsification systems where hydrolytic stability and biocompatibility are critical.

Application

• Phase-transfer catalyst in nucleophilic substitution reactions (e.g., alkylations, esterifications, and glycosylations)
• Emulsifier and stabilizer in cationic polymer dispersions and latexes
• Antistatic agent in synthetic fiber processing and nonwoven fabric finishing
• Formulation aid in agrochemical concentrates (e.g., herbicide and fungicide suspensions)
• Conditioning and foam-boosting agent in sulfate-free shampoos and hair conditioners
• Corrosion inhibitor additive in water-based metalworking fluids
• Hydrophilic modifier for silica and clay nanoparticles in nanocomposite synthesis
• Biocompatible dispersant in pharmaceutical nanocarrier preparation (e.g., liposomes and polymeric micelles)

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request. All batches conform to ISO 9001-certified manufacturing protocols and meet REACH registration requirements. Purity verification is performed via HPLC and titration, with identity confirmed by FT-IR and NMR spectroscopy. Trace heavy metals, residual solvents, and chloride impurities are quantified per ICH Q3 guidelines.

Storage

Preserve in a tightly closed container, protected from light. Store at room temperature (15–25°C) in a dry, well-ventilated area. Due to its hygroscopic nature, minimize exposure to ambient humidity—keep container sealed when not in use. Avoid storage near strong oxidizing agents or alkaline materials.
