Macrogol Cetostearyl Ether
Macrogol Cetostearyl Ether
Macrogol Cetostearyl Ether is a non-ionic emulsifier produced by reacting cetostearyl alcohol with polyethylene glycol (PEG). It helps oil and water mix together to form stable creams, lotions, and other emulsified skincare products while also improving their texture and spreadability. Depending on its PEG chain length, it may also contribute mild surfactant and solubilising properties, helping disperse oil-soluble ingredients throughout a formulation. It is valued primarily for improving formulation stability rather than providing direct skincare benefits.
🛡️
Safety: Generally well tolerated by most skin types. It is considered a low-risk cosmetic ingredient, although individuals with very sensitive skin may occasionally experience mild irritation.
