Mr. Kreidler. I'm an optometrist. I haven't worked in the to- 

 bacco industry but I thought perhaps "extractable nicotine" was a 

 term of art that perhaps was fairly commonly used. 



Mr. Sandefur. I don't have any knowledge of what that means, 

 no, sir. 



Mr. Kreidler. Let me go back, because I understood your an- 

 swer to mean one thing and the staff was not sure that I was un- 

 derstanding exactly the way it was said. 



You know my question was, does B&W use urea or other com- 

 pounds for these purposes, and those were to increase nicotine 

 transfer efficiency and nicotine impact or satisfaction. Now, you an- 

 swered about ammonia, but do they use urea or any other com- 

 pounds for those purposes? 



Mr. Sandefur. Congressman, I hesitate to, even though I've said 

 I think we use urea, I'm going to have to double-check that, and 

 I will be more than happy to let you know what we — what we do 

 use, urea or any other compound that we do, I just don't know. 



Mr. Kriedler. Fair enough. The BAT report stated in its sum- 

 mary and conclusion, that "The reaction of a smoker to the 

 strength of the smoke from a cigarette could be correlated to the 

 amount of 'extractable nicotine' in the smoke rather than to the 

 total nicotine content." 



In other words, extractable nicotine increases the impact of nico- 

 tine on the smoker. A subsequent report listed on chart 14, said 

 that "nicotine retention appears to be dependent principally on the 

 smoke pH and nicotine content." 



These statements are particularly interesting in light of Commis- 

 sioner Kessler's testimony Tuesday, as I'm sure you recall, he said 

 that ammonia is a base that also affects the pH of smoke. It ap- 

 pears that Dr. Kessler's testimony about ammonia correlates di- 

 rectly with the work that BAT did and was doing in 1968. 



In light of this information, can you tell us if you are aware of 

 any other tobacco ingredients that affect the pH or the base or the 

 acidity of nicotine? 



Mr. Sandefur. I'm aware that there are — there are other ways 

 to do that. I can tell you that some of my sister companies in fact 

 have other ways of doing that. I can't give you the technical aspects 

 of it. I can't even give you the name of what they call it. But I'll 

 be more than happy to provide that to you. 



Mr. Kreidler. OK. I appreciate that and would like to see that 

 information if I could, please. 



Mr. Sandefur. Yes. 



Mr. Kreidler. Now, I want to ask you about filters and if we 

 could pull up chart 16. Are you aware that BAT has studied the 

 feasibility of adding a substance called PEI to cigarette filters? 



Mr. Sandefur. No, sir, I'm not aware of that. 



Mr. Kreidler. OK. 



Mr. Sandefur. Congressman, I can tell you that I was told by 

 our legal counsel at the break that we have two patents or we have 

 one patent and I don't know who the other is assigned to with re- 

 gard to PEI. I don't know what it is, but I'm also told that our ex- 

 perts in this area, our scientists say that we don't use this patent 

 technology in any of our products.
