UNDECETH-3
Description
UNDECETH-3 is a non-ionic surfactant and emulsifier commonly used in skincare and cosmetic formulations. This synthetic ingredient is derived from ethoxylated undecylenic acid, a fatty acid obtained from castor oil. UNDECETH-3 functions primarily as a solubilizer and emulsion stabilizer, helping to blend oil-based and water-based components in various products.
The "3" in UNDECETH-3 refers to the average number of ethylene oxide units in the molecule, which influences its solubility and compatibility with other ingredients. This compound exhibits excellent cleansing properties and is often incorporated into facial cleansers, body washes, and shampoos. It effectively removes dirt, oil, and other impurities from the skin without causing excessive dryness.
UNDECETH-3 also acts as a mild foam booster, enhancing the lathering capabilities of formulations. Its low molecular weight allows for easy spreading and quick absorption into the skin. In skincare products, it can help improve the penetration of active ingredients, potentially enhancing their efficacy. While generally well-tolerated, individuals with sensitive skin should perform a patch test before using products containing UNDECETH-3, as with any new skincare ingredient.
