Description

Peg-8 Laurate CAS NO 35179-86-3 is a non-ionic surfactant derived from lauric acid and polyethylene glycol, functioning as an effective emulsifier, solubilizer, and emollient. Its balanced hydrophilic-lipophilic properties make it a versatile and mild ingredient for creating stable formulations. This compound is essential for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking reliable performance and skin compatibility.

Application

• Primary emulsifier and co-emulsifier in cosmetic creams, lotions, and ointments.
• Solubilizer for fragrances, essential oils, and hydrophobic active ingredients in clear aqueous systems.
• Key ingredient in mild cleansing formulations such as facial washes, shower gels, and shampoos.
• Used in topical pharmaceutical preparations for its emulsifying and skin-penetration enhancing properties.
• Acts as a lubricant and plasticizer in industrial applications and polymer processing.
• Intermediate in the synthesis of more complex specialty surfactants and esters.

Quality Control

Our Peg-8 Laurate is manufactured under a cGMP-compliant quality management system, ensuring batch-to-batch consistency and traceability. We perform comprehensive analytical testing, including assay, acid value, hydroxyl value, and saponification value determination, to meet stringent industrial and cosmetic-grade specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and easily oxidized; for long-term storage, consider using under an inert atmosphere (e.g., nitrogen blanket) to maintain optimal quality and prevent degradation.
