macrogol cetostearyl ethers

Macrogol cetostearyl ethers are non-ionic surfactants formed by the ethoxylation of mixed fatty alcohols (mainly cetostearyl alcohol) with varying numbers of ethylene oxide units (typically between 2 and 33). They are used primarily as emulsifying agents and solubilizers in pharmaceutical creams and ointments for topical application. These compounds help stabilize oil-in-water emulsions and improve the sensory properties of formulations. Macrogol cetostearyl ethers are widely used in dermatological preparations for dry or sensitive skin conditions such as eczema[2][5][6][7]. They act by reducing surface tension between ingredients to form stable mixtures but do not have direct pharmacological activity on biological targets.
