Description

Peg-12 Glyceryl Laurate CAS NO 51248-32-9 is a non-ionic surfactant derived from lauric acid and glycerin, ethoxylated with an average of 12 moles of ethylene oxide. This versatile compound is valued for its excellent emulsifying, solubilizing, and conditioning properties, making it a key ingredient in formulations requiring mildness and stability. It is primarily used by manufacturers in the personal care, cosmetics, and pharmaceutical industries to create stable emulsions and enhance product texture.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary or co-emulsifier in creams, lotions, and milky cleansers, providing a stable, smooth texture.
• Pharmaceutical Topicals: Used in ointments, creams, and medicated lotions for its emulsifying power and skin compatibility.
• Hair Care Products: Functions as a conditioning agent and emulsifier in conditioners, hair masks, and styling products.
• Skin Cleansing Systems: Employed in facial washes, shower gels, and makeup removers for its mild cleansing and foaming characteristics.
• Industrial Emulsions: Serves as an emulsifier for specialty industrial applications requiring non-ionic, water-soluble surfactants.

Quality Control

Our Peg-12 Glyceryl Laurate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets defined specifications for identity, purity, and performance. Certificates of Analysis (COA) are provided with every shipment, detailing key parameters such as assay, hydroxyl value, acid value, and water content. We can supply grades suitable for cosmetic (INCI compliance) and pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; for long-term storage, consider an inert atmosphere (nitrogen blanket). Keep away from strong oxidizing agents.
