Undecyl ether is commonly used as a surfactant in various industrial and household cleaning products due to its ability to reduce surface tension and improve the mixing of oils and water. It is also utilized in the formulation of personal care products, such as shampoos and lotions, where it acts as an emulsifier to stabilize mixtures of oil and water. In the textile industry, it serves as a wetting agent to enhance the penetration of dyes and other chemicals into fabrics. Additionally, undecyl ether finds applications in the production of lubricants and metalworking fluids, where it helps improve the performance and longevity of the products. Its mild and non-irritating properties make it suitable for use in sensitive applications, including certain pharmaceutical formulations.
