Stearamide Amp

What is Stearamide Amp?

Stearamide AMP is a synthetic cationic surfactant formed by amidation of stearic acid—a saturated fatty acid from vegetable or animal origins—with subsequent neutralization using 2-amino-2-methyl-1-propanol. It falls under amide-based surfactants commonly incorporated into rinse-off personal care items like shampoos, body washes, and conditioners. Functionally, it reduces interfacial tension to promote mixing of oil and water, aiding in effective removal of soils and sebum. It also amplifies foam density and endurance for a superior sensory experience during application, while modulating rheological properties to ensure optimal spreadability, stability, and dispensing ease in formulations. This multifaceted action supports clean-rinsing performance without compromising mildness.
