Overview
Triethanolamine lauryl sulfate (CAS 139-96-8 ), also known as TEA-Lauryl Sulfate and marketed under trade names such as Drene and Texapon TH, is an anionic surfactant used across personal care and cosmetic manufacturing.
It delivers foaming, emulsification, and cleansing performance in rinse-off formulations where mildness and compatibility with other ingredients are priorities. In shampoo manufacturing, it functions as the primary foaming and cleansing agent.
The compound works by solubilizing sebum and styling product residues from the scalp and hair shaft. Body washes and liquid hand soaps rely on it to generate stable, dense lather while maintaining compatibility with conditioning additives.
It is also used in fragrance systems, facial cleansers, and shaving creams, where its emulsifying action helps suspend oils and particulates for effective rinsing. This ensures a clean finish for various consumer applications.
Formulators working on specialty cleansing products use it to adjust foam profile and viscosity response. It is often used in combination with amphoteric or nonionic co-surfactants to achieve specific performance goals.
Triethanolamine lauryl sulfate is typically supplied as a clear to pale yellow viscous liquid. It is available in cosmetic-grade specifications, with active matter concentrations commonly around 40% for industrial use.
Buyers should confirm active content and pH range with suppliers when qualifying batches for formulation consistency. Adhering to these parameters ensures the final product meets the necessary stability and performance requirements.
