PROCESS OF MAKING- SOAP.

SPECIFICATION forming part of Letters Patent No. 700,229, dated May 20, 1902.

Application filed August 18, 1900. Serial No. 27,336. (No specimens.)

" Be it known that I, TOMMASO PARZIALE, a

' subject of the King of Italy, residing at'Alexandria, Egypt, have invented certain new and useful Improvements in the Manufacture of Soap, of whichthe following isa specification. This invention relates to the manufacture of soap having an oleaginous base, andin carry.-

of the ammonia-gases is to, be found-in the chemical reaction between the nitrogenous matters of the flour-and the caustic alkali. The mixture thus prepared cold is now left to stand for fiverto six hours. The purpose "is to avoid the formation of small lumps.

The rest after mixing serves to facilitate perfect amalgamation. vThereupon a'solution is added of a caustic base or sodium hydrate,

(soda of 30 Baum,) about fifty per cent., by

volume, and the mixture is thoroughly agitated. When furrows begin to show behind the beater, the mixture is placed in special boxes, in which it is left for three days, after which time it may be cut in the usual manner. To the solution of caustic soda or sodium hydrate (formula NaOH) may be added silicate of soda, alum, talc, cocoanut-oil, suit able perfume or essence, and the like, according to whether 'it is intended to prepare a cheap soap or one that is perfumed. There may be added silicate of soda or talc, besides other oils or-essences, 850., according to whether cheaper soap has to be produced or perfumed soap. This will facilitate the development of an ammoniacal gas. This proportion of talc and carbonate of lime may be from twenty to thirtyper cent. If it is desired'to obtain a soap as hard asthatmauufactured from olive-oil, twenty percent. of

silicate ofsoda is added. 1

"It is immaterial whether the vessel is of iron or zinc.

The'ammonia-gas is derived from the chem-- ical reaction resulting from the combination of the nitrogenous matters (in floury condition) with the materials of the, alkaline and caustic base, (NaOH.) To increase thedevelopment of this gas, it is only 'necessary to add tothe nearly-condensed soapy mass two half water and one-half alum in a well-mixed condition. As a consequence ofthis last addition and theqreaction brought about th'ere by after about three days the s oaplhas lost all its causticity,]beca'use the excess of hydrates has evaporated as gas, and thus a neutral soda oleate is obtained.

,Zinc is the material of which the vessel is formed, since this metal is less liable to corrode through the action of the causticalkali. The mixture of oil-and flour after having per cent. of a hot solution, consisting of onebeen worked in a cold state must rest from five to six hours, so that there may be brought about an absorption of those parts'w-hich are the most difficult ones to be absorbed-above reaction of the saponification.

I claim as myinvention- The process described consisting in mixing cold cotton-seed oil and flour containing gluten together, allowing the mixture to stand all, the glycerin-in order to facilitate, the

and then mixing with the said mixture caustic soda, substantiallyas described.
