Description

Peg-30 Glyceryl Isostearate is a non-ionic surfactant and emulsifier derived from isostearic acid and glycerin, ethoxylated with 30 moles of ethylene oxide. This versatile compound is prized for its excellent emulsifying properties, stability, and ability to create smooth, elegant textures in formulations. It is an essential ingredient for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking high-performance, skin-compatible ingredients for creams, lotions, and other emulsion-based products.

Application

• Primary Emulsifier in oil-in-water (O/W) creams, lotions, and serums for face and body care.
• Stabilizing Agent in cosmetic and pharmaceutical emulsions to prevent phase separation and ensure product shelf-life.
• Texture Enhancer in skincare formulations, providing a rich, non-greasy, and easily spreadable feel.
• Key Ingredient in sun care products, helping to stabilize UV filters in sunscreen formulations.
• Base Component for making self-emulsifying bases used in topical drug delivery systems.
• Conditioning Agent in hair care products such as conditioners and styling creams for improved manageability and softness.
