CETEARETH-20

Description

Ceteareth-20 is a versatile emulsifying and solubilizing agent commonly used in cosmetic and skincare formulations. This synthetic ingredient is derived from cetearyl alcohol and ethylene oxide, resulting in a nonionic surfactant with excellent emulsifying properties. Ceteareth-20 has an HLB (Hydrophilic-Lipophilic Balance) value of approximately 15.2, making it highly effective in creating stable oil-in-water emulsions.

In skincare products, Ceteareth-20 serves multiple functions. It helps blend water-based and oil-based ingredients, ensuring a smooth and uniform consistency. This ingredient also acts as a thickening agent, improving the texture and viscosity of formulations. Ceteareth-20 enhances the spreadability of products, allowing for easier application and better absorption into the skin.

Due to its solubilizing properties, Ceteareth-20 can help incorporate fragrances and essential oils into water-based products. It also functions as a mild cleansing agent, assisting in the removal of dirt and oil from the skin. While generally considered safe for use in cosmetics, some individuals with sensitive skin may experience irritation. As with any skincare ingredient, patch testing is recommended before widespread use.
