You want to know the detergent composition of an extract of a shampoo. You spot the sample on a TLC plate and develop it in dichloromethane and observe a single spot at Rf 0.95. Does this verify that only a single detergent compound is in the extract? What specifically can you do to gain more information about the composition of the shampoo extract?
