Dear "r. Lundgrens
Thank you for your letter of June 3 bringing to our attention tlie recent action of the FtDA in removing FD'.C Yellow Fo. 3 from the approved list. Our Toxicological Depart lent had also brought this action to our attention so we ore already in the process of replacing the Yellow Vo, 3 v'th a suitable substitute.
Mr. J. A. Pomeroy is now handling rigid vinyl ir our department
so I have referred your letter to him.
will probably contact you when
the substitution of another colorant has been completed.
Thank you again tor bringing this meiter to our attention.
Very truly yours,

Probably several o! the questions you ask In your letter of Kerch lpth
J*
were raised by an Inaccuracy In *y previous letter to you of
yy,/Jv'
December 1?, 1956, In that letter I referred to the rigid vinyl
shootin" which had proved acceptable to the F,D.A. as VCA-3U00 and VCA-3^30; the designation should have boon VCAB-lbOO and VCAB-3k20* Perhaps the following comments, In the sane omior as the questions la
your letter of Harch 15th, will help answer the questional
1* lour designation VA--31*00 Ivory 125 probably should read TCA-JliOO
Ivory 125 - ell of our calendered rigid vtryls will have a "C" as the second letter to Indicated calendered". We use a b-letter prefix before
the compound number to Indicate a eorqxrund under the supervision of our Development Dopartaant, Vhm the eenpound Is transferred to the responsi bility of the Kcnufadoring Department, the fourth letter Is dropped to Indicate this transferral, Thus VCAA or VCAB or VCAC beeonce merely VGA When transferred. In ay letter of December 16, 1956, X was anticipating
this transferral which still has not occurred. The fourth letter In the
developnent designation Is a serial letter indicating minor modifications of the base ewpeund which began as VCAA, If a change was at all
significant, It would require a change In base mnber and not Just a
letter change.
The fonmilatlon for VCAB-3&00 Ivosy 125 8td (IV stands for Ivory and 9td for "standard surface") was the soe submitted to the ?.BA, and the cna which they found acceptable.
f. The VCAB-3120 Ivory 125 9td was the flroulatlon sUbnlttad to the P,DA. and the one which thay found acceptable.
9 He had not been aware ef the announeenrot la the Federal Register that fS k C fellow lo, 3 was being onsLi*red for removal from the list ef certified dyes, He know the VDtC fellow Vs, 1 Is being considered for
delisting and Jure already switched to other colorants whore possible, hot

If the FW Tellcw Mo. 3 Is also Doing considered for dollsting, vs shall lanediately look for a substitute yellow which Is in good standing In anticipation of a final unfavorable report on the Mo. 3* this we would probably wish to do even if the No. 3 is not finally delisted If thero Is axy Question about its being acceptable,
bt We knew of no significant chemical changes which would occur when either of the formulations discussed above are merely dissolved in solvents and applied as coatings.

Dear Mr. Key:
Please refer to sqr letter of Kerch 15 pertaining to lnforaatlon about two of your plastic coating aaterlale, plus contents as re

1 would like to extend this Inquiry and to request this inforaatloo of your coating YCAT->*20-Ivory 125. Has Food and Drug approved this Material for use ee a plastic coating for food containers? Further, I would appreciate your opinion ae to the likelihood of any cheat cal changes occurring In this formulation frost s redlssolvlng of the added plastic aod sizing this stock with new aaterlal.
The Sealrlght people hara expressed an urgency to this natter and your Lastedlate attention would he appreciated.

Are you coetemplntlng a substitution for the Yellow #3 color? k. Vfaet are your views as regards possible chwaloal changes occurring when aolded reeia (VA-3*00-Ivory 125) le redissolved la solvents and reaolded. It has bees called to our attention that same chemical modification aay occur as a result of the initial opeiatiou. Since you are such closer to the chemistry of the material, I would appreciate your views m the matter.
