Surface active agents. Determination of the active matter content of alkylamidopropylbetainesWhat is BS EN 15109 The active matter content of alkylamidopropylbetaines about? BS EN 15109 discusses surface active agents. A surface active agent (SAA) is a substance that reduces the surface tension of a liquid in which it is dissolved, thereby increasing its spreading and wetting properties. BS EN 15109 specifies a method for the determination of the active matter content of alkylamidobetaines in commercial surface active agents. Who is BS EN
