The Radiometric Technique. Explained by the Example of Adsorption and Desorption of 14C-labelled Distearyl-Dimethylammonium Chloride on Human Hair
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.
