PEG-100 Stearate — CAS 9004-99-3

Description

1. Product Overview

PEG-100 Stearate (CAS 9004-99-3) is a nonionic surfactant and emulsifying agent produced from polyethylene glycol and stearic acid, widely used to stabilize oil-in-water formulations. It is a critical ingredient in personal care, pharmaceutical, food, and industrial formulations due to its excellent emulsification, thickening, and texture-enhancing properties. Its ability to improve product consistency, stability, and sensory performance makes it a preferred choice for global manufacturers seeking reliable formulation solutions. PEG-100 Stearate remains strategically important as demand grows for high-performance emulsifiers in advanced cosmetic, healthcare, and specialty chemical applications.
