PEG-20

Description

Polyethylene glycol 20 (PEG-20) is a versatile synthetic compound widely used in skincare and cosmetic formulations. This water-soluble polymer is derived from ethylene oxide and functions primarily as an emulsifier, surfactant, and humectant. PEG-20 has a molecular weight of approximately 1000 daltons, allowing it to effectively penetrate the skin's outer layers.

In skincare products, PEG-20 plays a crucial role in improving texture and enhancing the solubility of other ingredients. It helps create stable emulsions by reducing surface tension between oil and water phases, resulting in smoother, more uniform formulations. As a humectant, PEG-20 attracts and retains moisture, contributing to improved skin hydration.

The ingredient also acts as a penetration enhancer, facilitating the delivery of active ingredients deeper into the skin. This property makes it valuable in formulations containing vitamins, antioxidants, or other beneficial compounds. PEG-20 is generally well-tolerated by most skin types and is considered safe for use in cosmetics when properly formulated.

However, it's important to note that some individuals with sensitive skin may experience irritation. As with any skincare ingredient, patch testing is recommended before widespread use.
