Ammonium Lauryl Ether Sulfate (commonly referred to as AES-Ammonium Salt) is typically a pale yellow viscous liquid or paste at room temperature, with a slight characteristic odor, and is readily soluble in water. As an anionic surfactant, it exhibits mild chemical properties, offering excellent detergency, foaming performance, and hard water tolerance, along with relatively low skin irritation. The "70" in its designation usually indicates an active matter content of approximately 70%. Based on its mild nature and rich foaming characteristics, its primary application is as the main surfactant in personal cleansing products, particularly suitable for formulating gel shampoos, foam baths, low-pH shampoos, and mild liquid detergents.
