Abstract

For studies on the location of active principles in biological material the radiometric technique (radioactive indicator method, tracer method) has become indispensable in many fields. This applies above all to the search for and development of pharmaceuticals, crop protection agents, additives for detergents, additives for plastics and increasingly also for surfactants. By the example of a cationic surfactant — distearyldimethylammonium chloride (DSDMAC) — it is to be demonstrated in the following that hair cosmetics too can be tested by radiometric techniques.
