Description

26-Hydroxy-3,6,9,12,15,18,21,24-Octaoxahexacos-1-Yl Stearate is a specialized non-ionic surfactant and emulsifier, synthesized from stearic acid and a polyethylene glycol (PEG) derivative. This compound is valued for its ability to effectively reduce surface tension and stabilize formulations, particularly in systems requiring compatibility with both aqueous and oily phases. It is primarily utilized by formulators in the personal care, pharmaceutical, and specialty chemical industries seeking reliable performance in emulsions and solubilization processes.

Application

• Cosmetic & Personal Care Formulations: Acts as a key emulsifier and stabilizer in creams, lotions, and ointments, providing a smooth texture and consistent product performance.
• Pharmaceutical Excipient: Used as a non-ionic surfactant in topical drug delivery systems to enhance the solubility and bioavailability of active pharmaceutical ingredients (APIs).
• Industrial Lubricants & Additives: Serves as an emulsifying agent and lubricity additive in metalworking fluids, synthetic lubricants, and mold release agents.
• Agrochemical Adjuvants: Functions as a surfactant in pesticide and herbicide formulations to improve wetting, spreading, and adherence on plant surfaces.
• Textile & Leather Processing: Employed as a softening agent, lubricant, and antistatic agent in fiber processing and leather finishing.
• Paints & Coatings: Used as a dispersing agent and flow improver to ensure uniform pigment distribution and stable emulsion paints.

Quality Control

Our production of 26-Hydroxy-3,6,9,12,15,18,21,24-Octaoxahexacos-1-Yl Stearate adheres to stringent quality management systems. Every batch is tested against established specifications to ensure consistent purity, performance, and safety for its intended industrial applications. Certificates of Analysis (COA) documenting key parameters such as assay, acid value, hydroxyl value, and moisture content are provided to guarantee traceability and compliance with customer requirements.

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); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
