I could have told you as much, Caroline. The funny thing is that there are refined coal tar products for psoriasis, but how do the manufacturers know what to refine when nobody knows what the active fractions are? It never worked very well for me and these days I would sooner use an emollient and minimise the mess. When I did use it I ended up changing to Stockholm tar based topical as the amount of tar I was using was making me sick. It is toxic stuff!
