Description

Polyethyleneglycoldimyristate is a non-ionic surfactant and emulsifier derived from polyethylene glycol and myristic acid. This compound is valued for its excellent emulsifying, solubilizing, and conditioning properties, making it a versatile ingredient in formulations requiring stability and smooth texture. It is primarily used by manufacturers in the personal care, cosmetics, and pharmaceutical industries for products such as creams, lotions, and ointments.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emulsifier and stabilizer in creams, lotions, and makeup products.
• Pharmaceutical Topicals: Used as an excipient in ointments, gels, and dermatological preparations for its skin-conditioning effects.
• Industrial Lubricants & Release Agents: Serves as a component in synthetic lubricants and mold release agents.
• Textile & Fiber Processing: Functions as a softening agent and lubricant in fiber treatments and spinning operations.
• Food-Grade Emulsifiers (where specified): Can be used in food contact applications or as an indirect food additive, subject to specific grade and regulatory compliance.
• Agricultural Adjuvants: Employed as a surfactant in pesticide and herbicide formulations to enhance spreading and adherence.

Quality Control

Our Polyethyleneglycoldimyristate is produced under a strict quality management system. Each batch undergoes rigorous testing for critical parameters including identity, assay, acid value, saponification value, and moisture content to ensure consistency and performance. Certificates of Analysis (COA) are provided with every shipment and are available upon request.

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); keep the container tightly sealed to minimize exposure to atmospheric humidity.
