Description

Peg-2 Dioleate CAS NO 134141-38-1 is a non-ionic surfactant and emollient derived from oleic acid and polyethylene glycol. This compound is valued for its excellent emulsifying, lubricating, and softening properties, making it a versatile functional additive. It is primarily used in the formulation of personal care products, industrial lubricants, and textile processing aids where stable emulsions and smooth texture are required.

Application

• Cosmetics & Personal Care: Acts as an effective emollient and co-emulsifier in creams, lotions, and hair conditioners to improve skin feel and product stability.
• Industrial Lubricants & Release Agents: Serves as a lubricant and anti-static agent in metalworking fluids, mold release formulations, and fiber processing.
• Textile Processing: Used as a softening agent and lubricant for fibers and yarns to enhance processability and final fabric hand.
• Agricultural Adjuvants: Functions as an emulsifier and spreader in pesticide and herbicide formulations to improve coverage and efficacy.
• Leather Processing: Employed as a fatliquoring agent to soften leather and improve its durability and texture.
• Paints & Coatings: Acts as a flow improver and pigment wetting agent to enhance the application properties and finish of coatings.

Quality Control

Our Peg-2 Dioleate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent purity, performance, and compliance with relevant industry specifications. Certificates of Analysis (COA) documenting key parameters such as assay, acid value, saponification value, and appearance 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 material is easily oxidized; for long-term storage, consider keeping it under an inert atmosphere such as nitrogen to maintain product integrity. Keep away from strong oxidizing agents.
