Dispelling the 'Law of Wiechers' and Maximizing Actives Delivery

Why Hadgraft calls this the "Law of Wiechers" is still beyond my comprehension but if it helps formulators to deliver their actives better, it is fine with me. Then my contribution to cosmetic science will not have been in vain. In the last 35 years, Hadgraft has already done more for cosmetic science than he can ever realize; naming a bit of non-science, aka nonsense, after me is probably the latest—but I am sure I will survive.

To my friend and colleague, congratulations on your 60th birthday. This column is to thank you for all your contributions to skin delivery science and cosmetic science. But explain one thing to me: Why do you love lukewarm British beer? After all, the level of ethanol in that stuff is only 3%!
