Isopropylamine Dodecylbenzenesulfonate
What is Isopropylamine Dodecylbenzenesulfonate?
Isopropylamine dodecylbenzenesulfonate is a synthetic compound formed by neutralizing dodecylbenzenesulfonic acid, a linear alkylbenzene sulfonate, with isopropylamine. This creates an amine salt version of the surfactant, commonly employed in rinse-off cosmetics such as shampoos, shower gels, and facial cleansers. As an anionic surfactant, it possesses a negatively charged hydrophilic head and a hydrophobic tail derived from the dodecylbenzene chain. In products, it functions by disrupting the surface tension between water and oils or dirt particles. This action promotes the creation of micelles—spherical structures that encapsulate soils—allowing them to be easily rinsed away. Additionally, it generates foam, improving product spreadability and user experience during washing. Its use is primarily limited to leave-on products to reduce any potential buildup on the skin or hair.
