(Cl. 167-82) This invention relates to improvements in'toilet powders and method ofimanufacturingthe same, :tandw-has for its principal" object tonproduce a anewcandimproved powder incorporating 'therer zivitlrin ainovelmanner one 501 more of the-volatile alcohols so as to produce a powder having marked c cooling" and soothingrefleots,and in-:which said :Eefiectseare.maintained for'some time after use.
zaA further object aofitheinvention is to produce 11101 atttoiletr powders ofisther. characterdescribed, in
rwhichitheazadvantageous properties'may =be 're- -.:.ta'ined=over a relativelyxlong-periocl of time when *dtepttin a suitable rcontainer,*butrirrwhich'release i J :fobthe:sactiveuelements' is'spromot'ed by applying imeowder to theiskinJ Other 'obje'cts-"of'the'in- :='vention wiillappear from'atime to ztimee as the iol-lowing 'descriptionwproceeds.
Menthol; thymol=:and- =simi1ar' normally solidalcohols'have-been widely used in medicinal and toilet preparations forltheir cooling 1 properties,
this being largely due, of course;-to"tlieir high vapor pressure, but heretofore it has-not been 'deemed prac-tical to' use suchingredientswin a "toilet-powder; due tothe unstabilityi'of such 'relatively" dry mixtures wherein the' hi hly-fv'olatile -ingredients rapidly I disappear and'the powder quickly 'loses' its strength "when keptincontainers of "commercialor ordinaryiormf Talcjthe basic 3 ingredientof most toilet powders because of it's desirable smoothness and other-physical characteristics, hasmefely stir-f ace contact" for the 're- *te'ntion or'adsorptiom of *hig'hlyyolatile ingredientssuch' as mentholand thymol. Solutions-or g-emulsions 'of'these lattersubstances sprayed upon orrubbed into the tale are soon-evaporated. Similar1y,"other basic'ingredients of toilet powders'such as'zinc stearate, are not capable of retaining such alcohols.
Z140 In carrying outmy invention, I proyide a toilet powdenhaving as usual a base of talc, zinc stearateor thelike, but in addition I'provide a certain amount of highly porous or'absorbent material;preferably. consisting of diatomaceous 5 earth,'otherwise known as kie'selguhr, which con- "sists of the minute 'frustules andfragrnents of diatoms, .or in other words, the silicious remains of micrcscopiclalga occurring in the natural de posits, usually fossiliferous As is well known.
- 'the'diatoms consist of microscopic cellular structures, .so small'that the material is highly absorbentin its finest form; This material isrthor- 'oughly' impregnated with the solid alcohol, .in such manner that the latter enters into the cells v. 5 onporousstructurerof. the diatoms and is held apertures such as usuallyemployed in the. cover threinso as to greatly-lessen its surface-contact withthe air. 7
Furthermore, I increasethe lastingieflect of the -,c,001i ng vvapors bythezad-dition of certain? mentho1-esters, which hydrolize in contact'withmois-a 5 ture from the-skin.-and airgproducing additional menthol as well as theaoids of the esters, which acids: are neutralized by. a; -,suitable:, agent added for that purpose.
Referring now.- more specifically to the-propor tions of the severalingredients and the methods of: preparing-thei same which I- have! found to give most satisfactory results, asuggestedfiormula is substantially as follows: I w
. The, ingredientsof paragraphsjlBliand TLC) i above. are. preferably.. incorporated, as separate groups, beforemixine withlthe baseincluded in paragraph (A),,as w'il1hereinafterappear. v
One methodofimpregnating thediatomaceous "earth with e the [alcohols nmentioned consists in vaporizing the, latter. and, applying the vvaporunder moderate heatiand pressure .to a batchof idiatomaceousiearth contained in an autoclave or other enclosed container, r preferably...provided .with. asuitable agitating device sothat theyapors; may .be thoroughly, incorporated in the, di-
1 atomaceoussearth without; contactwith theatmosphere. .The batch isthen cooledwhile still inthe container. ,sothatnthe v,vapors. may enter the cellular structure of the diatoms, through capillarity andcondensatlon. I find mostsatisiactory results are obtained by limiting the rela- 'tive proportions of diatomaceous earthiand .talc
toisubstantially theamounts su gestedinasmuch as larger amounts of, diatomaceous earthtreated has described have a tendency to. afiectthe. free running properties of the powder, andito produoe a tendency to cake or clog the relatively .small of 'dispensing.cans, The proportionsof the solid alcohols can be varied somewhat, dependin'gupon the strength .desired or preferenoefor character- .istic odorvjof the 'differentalcohols. tThehdegree ofi'absorbentvpowders of thediatomaceousearth is naturally the limit of the amounts of the alcohols that can be fully absorbed, and the excess amounts will have a tendency to disappear from the mixture in a relatively short time.
The diatomaceous earth, being a natural product, may vary somewhat in effectiveness as an absorbent, depending upon the specific type and size of the diatoms constituting the particular deposit employed, and the mode of preliminary treatment. I find that a purified air-floated white product may be obtained through the pulverizing of the crude diatomaceous earth, which product being easily obtainable in commercial quantities, is highly desirable for the'purpose.
After the diatomaceous earth has been impregnated as above described, it .is intimately mixed with the base materials including talc, zinc stearate and borax, by the usual mechanical processes known to the art.
The menthol esters included in paragraph (C) -of the'suggested'formula above are of similar characteristics and may be used either separately or together. They are preferably added to the base independently of the impregnating process of the diatomaceous earth as above described,
since such process has a tendency to break down v the esters. As a preferred method of application, the esters are dissolved in ethyl alcohol and applied in the form of a solution or spray at atmospheric temperatures to the base and the impregnated diatomaceous earth, and combined, if
' desired, with a suitable perfume such as the lilac suggested. As an alternative method of application, the esters may be finely divided, and mixed directly with the base and impregnated diatomaceous earth.
Amongother absorbent or semi-absorbent materials which most nearly approach the properties of diatomaceous earth for the purpose of my invention, may be mentioned pumice, asbestos,
or chalk, the latter made up .of microscopic shells of calcium carbonate.
The talc may be replaced by zinc stearate as the principal base, or the latter may be varied in proportions desirable for its well known antiseptic and adhering properties. The borax is added as a neutralizing agent for the. menthol esters, as will hereinafter more fully appear. Other neutralizing agents may be used, as for instance calcium carbonate in the form of chalk.
As a modification of the process of manufacture above described, the diatomaceous earth may be mixed with the base before it is impregnated by the solid alcohol. but in general be found that such process involves the handling of much greater bulk of material and an unnecessary increase in amount of the alcohols used, some of which is taken up by the base by surface contact only, and is likely to escape from the mixture by volatilization during the preparation or before the powder is put to use.
air, and especially the perspiration of the skin.
mild acet c or propionate acids resulting from such hydrolysis are neutralized and rendered innocuous by the borax or similar neutralizing agent employed. Such agent as a secondary function, also serves to neutralize any acids of the perspiration.
A further advantage, which is even more important from the commercial standpoint, is the lasting effects of the essential properties of the alcohol ingredients such as menthol and thymol, whereby the product maintains its strength and cooling effects for relatively long periods of time, when kept in containers of commercial form. In fact, the secondary cooling effect from hydrolysis of the esters may be maintained indefinitely, while the initial effect from the absorbed alcohols is easily retained as long as a can of average size lasts, when ordinary caution is observed in keeping the can or container closed when not in use.
As a further advantage of my improved powder, the diatomaceous earth content has a marked property of removing the objectionable shine" noted with ordinary talcum powders, this property of the diatomaceous earth being due partly to its physical characteristics as distinguished from the flaky; shining crystals of talc, and partly to its absorptive powers, by which it takes up excessive perspiration from the skin as the menthol and thymol become released therefrom by volatilization.
Although I have describedcertain preferred formula and modifications thereof, and certain processes of manufacturing my improved toilet powder, it will beunderstood that I do not wishto be limited to the specific formulae described, but that similar properties may be obtained by other compositions, either by change in propor- 'tions or by substitution of well known equivalents, '-and that other modified processes of manufacturemay be used, without departing from the spirit and scope of my invention. I do not, therefore, wish to be understood as limiting myself to the ingredients, proportions or processes herein disclosed, excepting as specifically defined in the' appended claims. 7 r
