PEG-55

Description

PEG-55 is a polyethylene glycol compound widely used in cosmetic and personal care formulations. This synthetic polymer functions primarily as an emulsifier, solubilizer, and viscosity-controlling agent. With a molecular weight of approximately 2,500 Daltons, PEG-55 exhibits excellent water solubility and compatibility with a broad range of ingredients.

In skincare products, PEG-55 helps to create stable emulsions, allowing oil and water-based components to mix effectively. This property is particularly useful in formulating creams, lotions, and serums that require a smooth, uniform texture. Additionally, PEG-55 acts as a humectant, drawing moisture to the skin's surface and helping to maintain hydration.

The ingredient's solubilizing capabilities make it valuable for incorporating water-insoluble active ingredients into aqueous formulations. This characteristic enhances the overall efficacy of skincare products by improving the delivery of beneficial compounds. PEG-55 also contributes to the sensory attributes of formulations, imparting a silky, non-greasy feel upon application.

While generally considered safe for topical use, individuals with sensitive skin should perform patch tests before widespread application, as some may experience mild irritation.
