(1) CONDITIONING AGENT 



(2) MISCELLANEOUS INFORMATION ABOUT THE 



TEST COMPOUND ADMINISTRATION 



(3) INDICATION THAT IN THE DATA SOURCE THERE 



IS INFORMATION ON THE EFFECT OF 

 pH ON THE CHEMICAL ACTION 



1 Presence of conditioning agents such as spreading agents, wetting agents, detergents, 



emulsifiers, etc. (Use this symbol when other more specific symbols cannot be used. 

 Examples: Tween-80 and Tergitol. 



2 Gelatin 



3 Gums (gum arable, gum acacia, etc. ) 



4 Synthetic colloids (polyvinyl alcohol, carboxymethylcellulose, etc. ) 



5 Agar; alginate 



Test compound is not pure; it is applied as a formulation . (A formulation is defined as a 

 product containing a given proportion of the test compound, the remaining ingredients 

 being disregarded and presumably inert. ) Use Symbol for indicating that the test 

 compound is administered as a mixture . 



Test compound is administered as a precursor (from which the test compound is biologically 

 synthesized or degraded); the action is demonstrated to be of the test compound and not of 

 its precursor. Include the NAME AND INFORMATION ABOUT THE PRECURSOR in the written 

 abstract portion of Field B on the Code Sheet. (Consult the Key. ) 



Test compound is one ingredient of a mixture of compounds administered in a test for the 

 action in Field T-2; the remaining compounds are written on the Code Sheet in this coding 

 field and the evaluation, dose, etc. , are based on the response to the mixture. (Consult 

 the Key. ) 



Data source contains information on the effect of pH on the action coded in Field T-2.
