42. The chemist shall safeguard his professional independence at all times and avoid any situation which would put him in conflict of interest. Without restricting the generality of the foregoing, a chemist is:(1) in conflict of interest when the interests concerned are such that he may be influenced to favour certain of them to those of his client or whereby his judgment and loyalty towards the latter could be unfavourably affected;
(2) no longer an independent adviser in respect of a given act if he finds a personal advantage, direct or indirect, real or possible, therein.
