Description
111;218Z
This invention relates to novel deodorant pre-parations such as liquid or solid deodorant soaps, lotions, aerosol sprays, sticks, creams, powders, oils and the like, which include as a bacteriostatic agent which inhibits the growth of odor-causing skin bacteria, e.g.; gram-positive bacteria, an organic solvent soluble hop extract.
BACKGROUND OF THE INVENTION
Prior art studies of the human skin have shown that epidermal tissue support~ a relatively large population of .~ , _ ( --~ 8 Z
microorganisms, which predominantly comprise bacteria. Skin bacteriz are divided into esseneially two categories: (1) trans~ent bacteria, which come and go during the course o ordinary day-to-day contact of human s~in with its ~nvironment, and (2) resident bacteria, which thrive on human sk~n over an indefinite period of time.
While transient bacteria are readily removed by normal washing with ordinary soap, resident bacteria are more di~ficult to remove because they are re deeply embedded in the skin. Resident bacte~ia can be classifi2d into two types, gram-positive and gram-negative, according to their reac~ion c to the well-~nown Gram staining method. Xt is knvwl~ that when gram-positive bacteria come in~o contact wi~ the axi~lary secret~ons of apocr~nQ sweat, which are normall~ ~e~ile and od~rless, gram-positive bacteria cause these sec~etions to ~eco~e malodorous, thus producing the typical acrid ~ody odor.
In contrast to gram-positive types of ~acteria, gram-nega,iv~
bacteria. arc not a cause of body odor. However~ o~er 99% of resident bacteria are o the odor-causing gram posi~lve ~ar~ety~
: ~ .
Thus, the pr~vention or amelioration o~ huma~ body odor can b~ brought about ~y reducing the n~m~r o~ resident gram-positive bacteria ;n or on the skin. ~his ran be &ccomplish-~ed by re~ular ~ashings with deodorant soaps and/or the appli-ca~ion of o~her deodorant prepara~ions surh as aerosol spra~
deodoran~s, stic~s, c~ea~s, etc., which contain ac~ive anti~
_ ~12182 bacterial ingredients.
It has now been discovered that when hops, i.e., the flower of the humulus lupulus plant, is extracted with : - .
an organic solvent and the solvent is removed, a residue, o~
extract, is obtained w~ich acts as an e~ective bacteriostatic agent in sOaps and other cosmetic preparatfons for appLicat~on to human skin and which prevents or ameliorates body odor. It -has been found, for example, that soap solutions containin~ -, ~ : : - ;
only relativély minor amount~, e.g., about lZo by weight, of ~ -the hop extract, effectively inhibit the growth of od~r-causing - skin bacteria such as Staphylococcus aureus and Staphylococcus --! - ;~ epidermis.
i ~ The antibacterial activity of hop ~xtract i~ the ~ - -~ ~- presenc2 of soaps and other preparations ~or human skin has ` -~ -- ; ~not been previously l;nown. Although certain constituents of . ..
hops have ~een kno~n to exext ntibacterial act~vity a~inst the very fastidious~microorganisms t~at exist in beer, it~is ; -unexpected that hop constituents can act as efectLve ant~
bact~rial ingredients ~n soaps and oth~r cosmetic composi~ions~
.. ~ : - .
hich have often been found to neutralize or destr~y ~e -~microbicidal or bacterios~atic power of antiseptic comp~nds.
Th~ hop extract of this invention possesses a numoer o~ other -properties, in addition to bacteriostatic activity, which make it suitable ~or use in deodorant preparations. It is-surprisingly co~.pa~;ble wi-Lh other ingredients employed in - _ 3 _ .' ~- .

deodorant preparations, substantive to human skin, i.e., sticks to human skin, soluble in soaps and oils, non-toxic to animal life and non-irritating to human skin.
Summary of the Invention In one particular aspect the present invention provides a deodorant composition for applying to human skin, said composition comprising an active bacteriostatic agent which is effective in inhibiting growth of gram-positive bacteria, and a carrier for said active bacteriostatic agent, wherein said active bacteriostatic agent comprises an organic solvent soluble extract of the flower of the humulus lupulus plant.
In another particular aspect the present invention provides a deodorant soap for application to human skin, said composition comprising a soap and an active bacteriostatic agent which is effective in inhibiting growth of gram-positive bacteria, wherein said active bacteriostatic agent comprises from about 1 to about 5% by weight of an organic solvent soluble extract of the flower of the humulus lupulus plant.
In a further particular aspect the present invention provides a method for producing a deodorant composition for applying to human skin to inhibit growth of gram-positive bacteria thereon, said method comprising the steps of contacting the flowerof the humulus lupulus plant with an organic solvent under conventional extraction conditions to obtain an extract containing humulones and lupulones, and admixing said extract with a carrier therefor, which carrier is selected from the group consisting of a liquid soap, a solid soap, a cream, a paste, an aerosol spray, a powder and a stick.
Description of the Invention Accordingly, the present invention provides, in its broadest aspects, a deodorant composition which is suitable jl/ -4-for application to human ski~ o~position comprising as an active odor preventing or ameliorating ingredient, an extract of hops in an amount at least sufficient to provide àntibacterial activity.
The bacteriostatic extract may be obtained by contacting the flower of the humulus lupulus plant with an organic solvent, using conventional procedures of extraction. Specific conditions for carrying out the extraction will, of course, vary, depending on the circumstances. Preferably, however, the hops are immersed in, or otherwise contacted with, an organic solvent at atmospheric pressure and ambient temperature, for a period of time ranging from about ~ to about 4 hours.
After contacting the hops, the organic solvent is removed and a substantially solvent free residue is obtained. The residue is a greenish viscous liquid, almost solid at room temperature having a pleasant sweet aroma.
This residue, or extract, is remarkably effective ~, --~ 4a-, , ., ~ ( ( ~ 8 2 in inhi~iting the growth of odor-causing skin bacteria, such as gram-pos~tive bacteria. The exact chemical composition of th~ extract is very complex, but it is known to contain a series of humulones and lupulones. ~owever, the humulone fractlon can be removed, e.g., by precipitation as a metal~ic salt, for instance, as a salt of lead or cal~ium and the ex~ra~
will still retain its bacteriostatic efectiveness.
~ broad variety of organic solvents can be used to carry out the extraction. Preferably~ however, the solvent is selected from among alkanes, especially alkanes ~ rom 5 to 12 carbon atoms, such ~s pentane, hexane~ heptane, octane~ -nonane, decane, dodecane, and the like; ~Lcol~ols~ ~uch a~ -methanol, ethanol, propanol, butanol, pen~anol~ hexanol~
octanol, nonanol, decanol, and the li~e; chlorinated hydro-c2r~0ns, suc~ as methyl chloride, methylene c~loride~ and the like; petroleum ether; and aromatic hydrocarbons~ such as benzene, toluene, xylene, naphtha, and the like.
The type pf carrier medium or vehicle which can be used for the bacteriostatic hop extrac~ can vary broadly~ Thus~
the deodorant comp~si~ions of this invention can comp~ise liquid ox solid soaps, crea~s, pastes, aerosoL sprays, powders, sticks, and t~e li~e. The method of prep2ration ~s no~ cxltical;
and conventiorlai procedures can be employed. Preferably, the hop extract i5 included in a soap, ~hich can oth~rwise be p~e-parcd in 8 con~Jentional ~anner, i.e., ~rom naturally occurring ~112182 triglycerides (animal and vegetable fats), by hydrolysis of the ester linkages, e.g " sodium stearate. The addition of the hop extract is preerably made during the crutchin~
operati~n.
The hop extract of ~his invention can also be incorporated into creams, pastes, sticks~ powaer aerosol sprays and the like. When the deodorant compos~ion -~Q prep~red in the form of a paste or cream, for example, the hop extrac~ can be dissolved in a base, or carrier~ comprised of an inert organic material, e.g., petroleum jelly~ hydro-genated lard, hydrogenated vegetable oil~ or ~he like~ or an emulsion of-such matarials with water. Dry solids such as talc, cla~, titani~m dioxide~ and the lihe, are then si~ed in 510wly, with mLxing, until the desired consistency is - -obtained.
By way o illustration, deodoran~ powders can be prepared by blending the hop extract with a ~ase ~aterial~
such as talc, corn starch, precipitated chalk, or the lik~-and sifting the blend. Deodorant sticks can be made, ~llustra-tively, by blending soap, e~ollients, ~ater, alcohol and the hop extract at an eleva~ed temperature, pourinO the mix~rs . .~
into a mold of the desired shap2, and allowing the blend to cool and hard~n.
~ `~ ' ' .
The hop e~tract of this inv~ntion is-also suitable for use in deodorant sprays, which are typically prepared from water and alcohol solutions of an antibacterial agent or astringent compound, perfume, preservatives, and the like, and a propellan~, e.g., Freon.
.
Other ingredients such as per~umes, emo~lients, emuls~fying agents, stabilizers, physiologi~lly a~ceptable coloring agents, and the like, can be added to the deodorant -composltions in minor amounts ~or their conventionally -employed purposes~
'. ' ' -- m e amounts ox the various ingredients in the deodorant compositions can vary broadly~ ng essen~aL
only that the bacteriostat~c hop extract ~s added in an amount which is at least sufficient to impart bac~eriostatic,`i.~
b3cterial gro~th inhibiting9 acti~ity. This amou~t will of course, vary~ depending on the composition o~ th~ parti~ulæ
deodorant preparation. In general, rela~ively minor amounts - -- are ef~ective,for example, quantities of as little as 1~ by weigh~ or less based on the total weigl~ ~f ~he deodorant composition. Preferably, amounts o from abou~ 1 ~o 2bou~ ~
