PEG-100

Description

PEG-100, or polyethylene glycol 100, is a versatile synthetic compound widely used in skincare and cosmetic formulations. This water-soluble polymer acts as an emollient, humectant, and solubilizing agent, making it a valuable ingredient in various personal care products. PEG-100 has a high molecular weight, which contributes to its ability to form a protective barrier on the skin's surface, helping to reduce transepidermal water loss and maintain skin hydration.

In skincare formulations, PEG-100 serves multiple functions. It enhances the texture and spreadability of products, improving their overall feel and application. As a humectant, it attracts and retains moisture, promoting skin hydration. PEG-100 also acts as an emulsifier, helping to blend oil and water-based ingredients, which is crucial for creating stable and effective formulations.

One of the key benefits of PEG-100 is its ability to enhance the penetration of other active ingredients into the skin. This property makes it a useful addition to formulations containing beneficial compounds that need to be delivered deeper into the epidermis. However, it's important to note that some individuals may be sensitive to PEG compounds, and patch testing is recommended for those with reactive skin.
