PEG-18 STEARATE

Description

PEG-18 Stearate is a versatile emulsifier and surfactant commonly used in skincare and cosmetic formulations. This synthetic ingredient is derived from the esterification of stearic acid with polyethylene glycol (PEG). Its primary function is to stabilize emulsions, allowing oil and water-based components to mix seamlessly in creams, lotions, and other personal care products.

The "18" in PEG-18 Stearate refers to the average number of ethylene oxide units in the molecule, which influences its hydrophilic-lipophilic balance (HLB). This particular composition provides excellent emulsifying properties, making it suitable for a wide range of formulations. PEG-18 Stearate acts as a thickening agent, enhancing product texture and consistency.

In skincare applications, PEG-18 Stearate helps create smooth, easily spreadable products that absorb well into the skin. It also contributes to the moisturizing properties of formulations by forming a light, non-greasy barrier on the skin's surface. This ingredient is generally well-tolerated and considered safe for use in cosmetics, though individuals with sensitive skin should perform patch tests before regular use.
