PEG-400

Description

PEG-400, or Polyethylene Glycol 400, is a versatile synthetic compound widely used in skincare and cosmetic formulations. This water-soluble polymer acts as an effective humectant and emollient, drawing moisture to the skin and helping to maintain hydration. Its low molecular weight allows for easy absorption, making it an excellent carrier for other active ingredients.

In skincare products, PEG-400 serves multiple functions. It enhances the texture and spreadability of formulations, creating a smooth, non-greasy feel. This ingredient also aids in stabilizing emulsions and can improve the solubility of other components. PEG-400 is particularly useful in cleansers, moisturizers, and serums due to its ability to dissolve both oil- and water-soluble substances.

While generally considered safe for topical use, some individuals may experience sensitivity. It's important to note that PEG-400 can potentially enhance the penetration of other ingredients, which can be beneficial for product efficacy but may also increase the risk of irritation in sensitive individuals. In formulations, PEG-400 is typically used in concentrations ranging from 1% to 10%, depending on the product type and desired effects.
