Description

Polyethyleneglycol Rosin Sesquiester CAS NO 61791-05-7 is a non-ionic surfactant and emulsifying agent derived from rosin acid and polyethylene glycol. This versatile chemical is valued for its excellent emulsifying, dispersing, and stabilizing properties in complex formulations. It is primarily used by manufacturers in the personal care, coatings, and agrochemical industries to enhance product performance and stability.

Application

• Personal Care & Cosmetics: Acts as a key emulsifier and stabilizer in creams, lotions, and hair care products, ensuring smooth texture and long-term formulation integrity.
• Coatings & Inks: Serves as a dispersing agent for pigments and fillers, improving color development, gloss, and the overall stability of water-based and solvent-based systems.
• Agrochemical Formulations: Used as an emulsifier and adjuvant in pesticide and herbicide concentrates, enhancing the spreading and adhesion of active ingredients on target surfaces.
• Adhesives & Sealants: Functions as a tackifier modifier and processing aid, improving the adhesive properties and application characteristics of various sealant products.
• Textile Processing: Employed as a softening agent and lubricant in fiber treatment and dyeing processes to improve fabric handle and processing efficiency.
• Industrial Cleaners: Utilized as a surfactant in industrial and institutional cleaning formulations for its degreasing and emulsifying capabilities.

Quality Control

Our Polyethyleneglycol Rosin Sesquiester is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent composition, performance, and purity. Key parameters such as acid value, hydroxyl value, saponification value, and viscosity are monitored. Certificates of Analysis (COA) documenting these specifications 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, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and should be kept in its original, sealed packaging to minimize exposure to atmospheric moisture. For long-term storage, consider using an inert atmosphere to prevent oxidation.
