Laureths

Description

Laureths are a family of synthetic emollients and surfactants widely used in cosmetic and personal care formulations. These ethoxylated lauryl alcohol derivatives are produced by reacting lauryl alcohol with varying amounts of ethylene oxide. The number following "Laureth" in ingredient names (e.g., Laureth-4, Laureth-23) indicates the average number of ethylene oxide units added.

Laureths function primarily as emulsifiers, helping to blend oil and water-based ingredients in products like cleansers, lotions, and creams. They also act as mild surfactants, contributing to the cleansing and foaming properties of personal care items. These ingredients exhibit good solubilizing capabilities, aiding in the incorporation of fragrances and other oil-soluble components into aqueous formulations.

The varying ethoxylation levels of different Laureths influence their solubility and performance characteristics. Lower-numbered Laureths tend to be more oil-soluble and have stronger emulsifying properties, while higher-numbered versions are more water-soluble and offer enhanced solubilizing effects. Laureths are generally considered gentle and well-tolerated by most skin types, making them suitable for use in a wide range of skincare and cosmetic products.
