   I,         ~o~d~a~

             One of the major Irarbaei~s in designing conventional oltnˇlar tar
             prodvetl is that very ~ph drew effort is Fe~ulred to obtain an aeaptsbla
             wuthful of rrmte In the initial puff, The newly launched RJR product
             PR~IER deawnstrates that good mouthful md truthful of "rmote" (but Mt
             necessarily taste) can be obtained by urrnq hfgh level af 9lycerol as
             opporedto relying solelyon ronventlonal tar', Mdltfonally, a
           - prelfmlnary study conducted under Project GREfNWf using high nleptlE
            ˇtobaes bFthcr with 12X glyeroi addition to the total blend prior to
            expansion (Rul level ca 9X), shcra that I produet oat be designed to
            deliver 499 tar, of which 2mg would be clasleal tar and 209 9lyearol,

             Tbnfon, for Ula flrrt tllel It would Ippar that we do not have to rely
             on generating nwlte from combustton of natural tobacco onlu and this
             proposal IIP~ It exploiting this nev finding In dweloping the nut
             generation of ultra-low tar products,

             Proposal

             Two different approaches are praposed under the c~oR objective:

              ~Pmaeh I to progress the project 9p29MXlT apprPd
                    based on conventional rod structure

              Approach II to nmbce the '91Ftml ChnotaW' vfth
                    the rtruetund rod kthnology, The tOOEYAe
    L               structure would appear to he ideally suited
    for th(s'i,e,:


              A: Blend 1 ~~91 all expanded with high gly#rot
              Bt Blend 1Ie191 conventional
              however, the resurractlon of this technology will be both time
              and cost consuming, Therefore, the Intltlal uploratfon should
              be based an lepnented elgarette rod using the are readily
              available a4mC technology,
