What is PEG-25 Hydrogenated Castor Oil?

PEG-25 Hydrogenated Castor Oil derives from castor oil extracted from Ricinus communis seeds, which undergoes hydrogenation to saturate its fatty acids, followed by ethoxylation with 25 ethylene oxide units. This creates a non-ionic surfactant commonly used in rinse-off cosmetics like shampoos, body washes, and conditioners. It functions by reducing surface tension for better foaming and cleansing, solubilizing hydrophobic ingredients such as fragrances into water-based formulas, and emulsifying oil-in-water systems to maintain product stability and smooth texture during application.
