104101l3 MALODOR COUNTERACTANTS
Cross-References to Related Applications None.
Field of the Invention This invention relates to the art of treatment of offensive odors, more particularly, to compositions and methods to counteract certain malodors.
Descripti_n of the Prior Art The art of perfumery began, perhaps, in the ancient cave dwellings of prehistoric man. From its inception, and until comparatively recently, the perfumer has utilized natural perfume chemicals of animal and vegetable origin. Thus, natural perfume chemicals such as the essential oils, for example, oil of rose and oil of cloves, and animal secretions such as musk, have been mani-pulated by the perfumer to achieve a variety of fragrances. In more recent years, however, research perfume chemists have developed a large number of synthetic odoriferous chemicals possessing aroma characteristics particularly desired in the art. These synthetic aroma chemicals have added-a new dimension to the ancient art of the perfumer, since the compounds prepared are usually of a stable chemical nature, are inexpensive as compared with the n~tural per-fume chemicals and lend themselves more easily to manipulation than the natural perfume chemicals since such natural perfume chem-icals are usually a complex mixture of substances which defy chemical analysis. In contrast thereto, the synthetic aroma chemicals possess a known chemical structure and may therefore be manipulated by the perfumer to suit specific needs. Such needs vary over a very wide spectrum. Accordingly, there is a great need in the art of fragrance compositions for compounds possessing specific olfactory characteristics~

104iO18 Heretofore a major effort in the art of perfumery has been directed to providing means of treating odors that are offensive to the human sense of smell. Such odors encompass a variety of odors such as bathroom-odor, kitchen-odor, body-odor, cigar smoke-odor, etc. Many products have been developed in an attempt to overcome these odors. So-called "room fresheners" or "deodorants" are illustrative of such products.
In general these products provide a masking effect by one of two mechanisms. The maskant fragrance is provided either to suppress the offensive odor by providing a more pleasing aroma in large quantities or by providing an aroma that blends with the offensive odor to provide a different and more desirable aroma.
Unfortunately, in both instances a large amount of fragrance must be utilized which in itself often proves to be offensive. ~urther-more, the offensive odor is usually still detectable at the levels of maskant fragrances that are reasonably tolerable. Accordingly, compositions and methods for counteracting such offensive odors which would substantially eliminate such odors without the above noted disadvantages are particularly desirable.
Particularly noxious odors are caused by compounds which have a pronounced tendency to either donate or accept protons.
Such compounds will hereinafter be referred to as "malodors".
They include the olfactory notorious classes of lower carboxylic acids, thiols, thiophenols, phenols, lower amines, phosphines and arsines.
Summary of the Invention The present invention provides novel compositions which are especially useful in view of their ability to counteract mal-- odors. Furthermore, novel methods are provided, i.e. the use of - 30 such novel compositions to counteract malodors.
The instant substance which exhibits this surprising ,- .
4~412SA
~ 041018 ability to counteract malodors is 4-cyclohexyl-4-methyl-2-pentanone (hereinafter referred to as "~MP").
Description of the Preferred Embodiments The term "counteract" as used herein means the effect on the human sense of smell and/or the malodor resulting in alle-viating the offensiveness of the malodor to the human sense of smell. It is not intended that this term be limited to any par-ticular mechanism by which such a result may be obtained.
Surprisingly CMP is capable of effectively counteracting malodors when utilized in small quantities. CMP can he used in many different mediums to counteract malodors. For instance, use in room fresheners or deodorants in the form of aerosols (sprays, etc.), liquids (wick type), solids (wax bases as in pomander, plastics, etc.), powders (sachets, dry sprays) and gels (solid gel sticks) are particularly preferred. Other illustrative uses are in clothes deodorants as applied by washing machine applications such as in detergents, powders, liquids, whiteners or fabric soft-eners or by other applications such as closet blocks, closet aerosol sprays, or clothes storage areas or in dry cleaning to overcome residual solvent notes on clothes; in cleansers such as disinfectants and toilet bowl cleaners; in bathroom accessories such as paper towels, bathroom tissues, sanitary napkins, towel-lets, disposable wash cloths, disposable diapers, and diaper pail deodorants; in cosmetic products such as antiperspirant and under-arm deodorantsj general body deodorants in the form of powders, aerosols, liquids or solid, or hair care products such as hair sprays, conditioners, rinses, hair colors and dyes, permanent waves, depilatories, hair straighteners, hair groom applications such as pomade, creams, lotions, etc., medicated hair care pro-ducts containing such ingredients as S-Selenium-sulfide, coal tar, salicy;ates, etc., or shampoos, or foot care products such as foot powders, liquids, or colognes, after shaves and body lotions, , 43-4125A
~.04101f~
or soaps and synthetic detergents such as bars, liquids, foams, or powders; in odor control such as during manufacturing pro-~esses, such as in the textile finishing industry and the printing industry ~inks and paper); in effluent control such as in pro-cesses involved in pulping, stock yard and meat processing, sewage treatment, or garbage disposal, or in product odor control as in textile finished goods, rubber finished goods, car fresheners, etc.;
in agricultural and pet care products such as dog and hen house effluents, and domestic animal and pet care products such as deodorants, shampoo or cleaning agents, or animal li-cter materials;
in large scale closed air systems such as auditoriums, and subways and transport systems.
The amount of CMP to be utilized depends, in general, on the particular malodor involved and its concentra*ion and on other variables such as the medium in which it is used and the temperature, humidity and air circulation. An effective amount should be used. In general, CMP is effective when present in the air (in which the malodor is located) at a level as low as about 0.01 mg./cubic meter of air. Any concentration above this amount will generally be effective. However, from a practical point of view, more than about 1 mg./cubic meter of air is probably un-necessary with even the most offensive and concentrated malodors.
~ MP can be prepared by reacting benzene with mesityl oxide to form 4-methyl-4-phenyl-2-pentanone which is then sub-jected to appropriate hydrogenation.
The following examples are ~iven to illustrate the in-stant invention in detail. It is to be understood that the specific details given in the examples are not to be construed as limiting the scope of the invention. The symbol "mg./cu. meter"
refers to the weight (in milligrams) of material prfse~t in one cubic meter of air.

and an exhaust fan was provided. The capacîty of the exhaust ~an was 14 cu. meters/mln. order to ir,sure satisfactory evacuation the exhaust fan was operated for five minutes between tests and an olfactory check was made to determine if any residual odor could be detected prior to conducting the next test.
After the test chamber had been suitably evacuated the malodor to be utilized was sprayed from the aerosol can for about five seconds. After a delay of from 10-15 seconds the fragrance composition aerosol was sprayed for about five seconds (five seconds being an average time such an aerosol would usually be used by a housewife). One minute thereafter a 10 member panel (consisting of 7 persons skilled in perfumery and odor evaluation and 3 persons having no such special skills but being familiar with fragrances in general) entered the test chamber~ performed ; an olfactory evaluation for detection of the malodor and recorded their observations. All tests were performed with only one (l) member of the panel ~eing aware of the identity of the material being tested.
Based on flow rates through the valves utilized in the aerosol cans the approximate amounts of aerosol containing the malodor concentrate introduced into the test chamber are: -Aerosol Containing Amount Malodor Concentrate(mg./cu.meter) Burned Tobacco 267 Body 166 Bathroom 267 The amount of aerosol containing the fragrance composi-tions introduced into the test chamber is approximately 260 mg./
cu. meter.
When the above described test procedure was carried out using each of the fragrance composition aerosols containing CMP
1~)4101~
(tested against each of the three above-mentioned malodors) at least eight (8) members of the panel could not detect the presence of the malodors. These are particularly surprising results be-cause when the floral bouquet fragrance composition aerosol not containing CMP is tested at least six (6) members of the panel detected the presence of the malodors.
Example 2 Four well known commercial products were also utilized in the above-described test procedures against each of the above-described malodors. (Amounts utilized based on 5 second spray):
Commercial Amount Product (mq./cu. meter) C ,150 With all of these commercial products at least six (6)members of the panel detected the presence of the malodors.

This ability of CMP to counteract malodors is particularly surprising in view of the fact that a closely related compound 4-cyclohexyl-3-methyl-2-pentanone, has little or no such ability.
