The classification given in the tables below is of active ingredients, and only forms the starting

this first-hand data. Only if this is not available should the formula be used, as shown in Part I on
page 4 to extrapolate the LD50 of the formulation from that of the technical product. In this event,
the single oral or dermal value of the LD50 given in the tables below should be used in the formula
