PEG-135

Description

PEG-135 is a high molecular weight polyethylene glycol (PEG) polymer widely used in cosmetic and personal care formulations. This synthetic compound is characterized by its long chain of ethylene oxide units, resulting in a viscous liquid at room temperature. PEG-135 functions primarily as a humectant, emollient, and solubilizing agent in skincare and haircare products.

As a humectant, PEG-135 attracts and retains moisture, helping to maintain skin hydration and improve product texture. Its emollient properties contribute to a smooth, soft feel on the skin, enhancing the overall sensory experience of formulations. In haircare applications, it can aid in detangling and improving manageability.

PEG-135 is also valued for its ability to solubilize various ingredients, facilitating the incorporation of both oil-soluble and water-soluble components in a single formulation. This property makes it particularly useful in cleansing products and emulsions. Additionally, PEG-135 can act as a thickening agent, helping to stabilize and improve the consistency of liquid formulations.

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