UNDECETH-40

Description

UNDECETH-40 is a non-ionic surfactant and emulsifier widely used in cosmetic and personal care formulations. This synthetic ingredient is derived from ethoxylated undecanol, a fatty alcohol, and belongs to the family of ethoxylated compounds. Its primary function is to reduce surface tension between oil and water phases, allowing them to mix smoothly and create stable emulsions.

In skincare products, UNDECETH-40 acts as an effective solubilizer, helping to incorporate oil-soluble ingredients into water-based formulations. It also enhances the spreadability of products, improving their texture and application. The "40" in its name refers to the average number of ethylene oxide units in the molecule, which contributes to its water solubility and mildness on the skin.

UNDECETH-40 is particularly useful in cleansing products, such as facial washes and shampoos, where it aids in removing dirt and oil without overly stripping the skin or hair. Its mild nature makes it suitable for sensitive skin formulations. Additionally, this ingredient can function as a viscosity modifier, helping to achieve desired product consistency. While generally considered safe for cosmetic use, as with any ingredient, individual sensitivities may occur.
