The sharp outs made in the Pigments Department's quota necessitated a search for satisfactory substitutes for those agents in the manufacture of many colors. Among the colors affected are the "latohung" pigments which, with the exception of RT-618-D, are large users of Spencers pars soap (N-484). Por example, a 2375 lb. batsh of RT-428-D calls for S8 lbs. of para soap. A laboratory series was run on RT-428-D and EM-A17-D in which tho para soap was omitted and other more readily available agents substituted. The products were checked for tinctorial properties, lightfastness, texture, ink mill behavior, and resistance to bleed* In the case of KT-428-D, two of the agents were used successfully in plant batobes* SUBSTITUTES TESTED Potassium labiate (N-358) Petronate (H-490) Distoline (N-641) Textile finishing oil (N-717) CONCLUSIONS BT-A26~Di Omission of para soap had no offeot on the general properties of KT-428-D. The para soap substitutes had no apparent effect on tinctorial properties, except for potassium l&urate, which yielded a very slightly lights? masstone, and Distoline, which yielded a very slightly darker masstone and weaker tint* All were equal to standard in lightfastness, texture, ink mill behavior, ink consistency, and in bleed in toluene, mineral spirits, 1*1 MEK-TCP, aloohol, and hot water. Plant trials were made substituting textile finishing oil (N-717) and Petronate (N-490) for para soap on an equal weight basis. The batch made with N-717 was equal in all respects to a eontrol batch} the lot treated with N-490 matched the control except for a darker masstone* On the basis of laboratory and plant data, para soap may be omitted from the KT-428-D formula* If it is felt that an agent is desirable to control uniformity of plant production, any of those listed oan be used, with the possible exception of Distoline* Application of the known variables should correct any minor variations in tinctorial properties* BH-417-D (Alumina hydrate-blanc fixe lake of BT-428-D)* Omission of para soap had no apparent effect on SX-428-D, but in the case of R8-417-D it gave a lighter masstone and a bluer tint* Consequently an egsni appears to be more essential in the 1N-417-D process* Potassium laurate and Petronate can be used with no change in the tinctorial properties* Both Dietoline and the textile finishing oil yield a Slightly lighter masstone, which may be corrected by application of the usual variables in the plant* All are equal to the standard in lightfastness, texture, ink mill behavior, ink consistency, and in resistance to bleed in paraffin or in animal fats* DUP050068932 Because of the similarity of the processes, it is probable that the subject agents say be substituted for para soap in HE-482-D, BK-4B4-D, RT-.597-D, and RT-663-D. mSSSBSSF--SSSBSKSSRSmCmSEmSSZ N*B. 3390, Expts. 24, 25 RT-423-D, lots 29223, 29292, 29426 DUP050068933
