To all whom it may concern Be it known that I, CARLETON ELLIS, a citizen of the United States, and resident of Larchmont, in the county of Westchester and State of New York, have made certain new and useful Inventions Relating to Fina chlorinated or other compounds having an acid tendency in which antacid materials are so incorporated as to be non-settling and to obviate or correct such tendency.

Chlorinated organic solvents, such as carbon tetrachlorid, chlorbenzol, chlor toluol, acetylene chlorid and so forth, are desirable as ingredients for paint or varnish removers because reducing or destroying their inflammable character. Such remover ingredients have in some cases an acid tendency, that is, either possess acid properties or have a tendency to form bodies of an undesirable acid character in connection with the ordinary alcoholic or other remover ingredients, as is also sometimes the case with other esterification products containing chlorin or other acid radicals. Effective antacid material is, desirable in removers of this character to prevent or neutralize such readilyaccomplished by thoroughly drying the soap and then dissolving it in hot alcohol, preferably after its pulverization and then incorporating the chlorinated or other penetrating solvents. Antacid material of this character may be used in removersin connection with loosening finish solvents, that is, solvents having a generally alcoholic character or action in removers, such, for

example, as methyl, ethyl, amyl, allyl, and.

denatured alcohols, acetone, methyl acetone,

methyl ethyl ketone, acetone oil, light oil of hard wood tar, butyrone and allied solvents.

in addition to the chlorinated finish solvents referred to other penetrating finish solvents, that is, solvents having a generally benzolic character or action in removers may be employed, including benzol, toluol xylol, cumene, benzin and other petroleum hydrocarbons and methyl, ethyl, amyl and other ethers and esteric compounds. Although not necessary in all cases suitable stiffening material may be employed, such as flour, starch, wood flour, whiting, infusorial earth and also film-forming stifi'ening material may be employed, such as waxes or waxy material, nitrated cellulose and other solid organic bodies having the property of forming'v evaporation retarding films on the removers. An illustrative remover of this character may be prepared by thoroughly drying a good sodium soap, such as a good grade of tallow or olive oil soap, by drying for several hours at a temperature of about 110 0., grinding the soap to a fine powder when it is sufiioiently dried for this purpose, and then thoroughly drying the soap powder. A quantity of this dried soap powder and a quantity of denatured alcohol may be put into a receptacle provided with a reflux condenser and boiled until the alcohol is saturated'with the soap. 5 parts of this alcohol soap solution may be diluted wlth 5 parts of denatured alcohol and the resulting solution mixed with. 9 parts of carbon-tetrachlorid' in which 1 part of ceresin has been dissolved, the various ingredients being, of course, thoroughly incorporated by agitation in a suitable stirrer or otherwise. 7 Q

' This invention has been described in connection with a number of illustrativegin gnedients, formulas, proportions and processes, to the details of which disclosure the invent1on is not, of course, to be limited.

What is claimed is 1. The finish remover comprising approximately 5 parts of denatured alcohol which has been saturated with dried pow.

dered sodium soap and incorporated with 5 porated 5 parts of loosening finish solvent material, and 9 parts of chlorinated solvent material and waxy stiflfening material.

3. The substantially fluent non-aqueous finish remover comprising approximately five parts of alcohol in which soapy antacid material has been dissolved and with which are incorporated five parts of loosening finish solvent material and nine parts of chlorinated solvent material and stifiening material.

4. The finish remover consisting substantially of volatile finish solvent material comprising loosening finish solvent material in which soapy antacid material has been dissolved and with which approximately equal proportions of penetrating solvent material including a chlorinated solvent has been incorporated.
