PEG/PPG-22/24 Dimethicone

What is PEG/PPG-22/24 Dimethicone?

PEG/PPG-22/24 Dimethicone is a synthetic polymer derived from dimethicone, a silicone base, modified with polyethylene glycol (PEG) and polypropylene glycol (PPG) chains. This creates a water-soluble silicone that functions primarily in rinse-off and leave-on hair and skin products like shampoos, conditioners, lotions, and creams. As a surfactant, it reduces surface tension to support cleansing, emulsification, and light foaming. Its emulsifying properties form a stable film at oil-water interfaces, preventing phase separation and ensuring even distribution of ingredients. This results in products with improved spreadability, reduced greasiness, and better sensory feel, such as silkiness on skin or hair without heavy residue. Commonly found in formulations needing balanced hydrophilicity and lipophilicity for versatile performance across personal care categories.
