Zeolites such as those marketed under the trade name Abscents� by the Union Carbide Corporation and UOP are known odor absorbers. However these commonly known solid odor absorbers, in addition to known activated charcoal odor absorbers, lose functionality when wet. Therefore, when wetted by body fluids or when carried in an aqueous solution, these odor absorbers are not preferred as they substantially lose their desired odor absorbent characteristics. Furthermore, zeolites can cause a "harsh" feel if too much is deposited onto the skin. The white zeolite powder and the black activated charcoal can also be rather visible and unsightly when applied to surfaces such as skin.
The present invention encompasses a method of controlling environmental malodors on skin comprising the application to the skin of a composition comprising from about 0.1% to about 5%, by weight of the composition, of solubilized, water-soluble, uncomplexed cyclodextrin; from about 0.1% to about 36%, by weight of the composition, of an oil phase selected from the group consisting of emollients, moisturizers, and skin protectants; one or more surfactants; from about 0.004% to about 2%, by weight of the composition, of a hydrophilic, volatile perfume composition; and an aqueous carrier.
The methods for controlling environmental malodors of the present invention comprise the application of a malodor-absorbing composition comprising solubilized, water-soluble, uncomplexed cyclodextrin and a hydrophilic, volatile perfume composition. The invention compositions can be applied directly as a spray, poured from a bottle and applied by hand, or applied via a pre-formed wipe which is wet with the composition when it is applied to skin and/or hair. The present invention also relates to an article of manufacture comprising the environmental odor-absorbing composition incorporated into a flexible dispensing means.
The present invention encompasses a method of controlling environmental malodors on skin comprising the application to skin of a composition comprising from about 0.1% to about 5%, by weight of the composition, of solubilized, water-soluble, uncomplexed cyclodextrin; from about 0.004% to about 2%, by weight of the composition, of a hydrophilic, volatile perfume composition, from about 0.1% to about 36%, by weight of the composition, of an oil phase selected from the group consisting of emollients, moisturizers, and skin protectants; one or more surfactants; and an aqueous carrier. These compositions may also optionally comprise one or more of the following: hydrophobic antimicrobials; water-soluble antimicrobial preservatives; low molecular weight polyols; zinc salts; water-soluble polymers; soluble carbonate and/or bicarbonate salts; chelating agents; zeolites; activated carbon; and mixtures thereof.
Suitable nonionic surfactants are fatty acid esters of ethoxylated sorbitans; polyethylene glycol-polypropylene glycol block copolymers, such as Pluronic�, and Pluronic R� surfactants sold by BASF-Wyandotte Corp. ("BASF"), Wyandotte, Mich.; Tetronic� and Tetronic R� surfactants sold by BASF, ethoxylated branched aliphatic diols such as Surfynol� surfactants sold by Air Product & Chemicals, Inc. Allentown, Pa; ethoxylated aliphatic alcohols and carboxylic acids; polyethylene glycol diesters of fatty acids; polyalkyleneoxide polysiloxanes; and mixtures thereof.
Tetronic� surfactants: ##STR1## and/or
Reverse Tetronic� surfactants: ##STR2## wherein EO is an ethylene oxide group, PO is a propylene oxide group, and n and m are numbers that indicate the average number of the groups in the surfactants. The average molecular weight of the polyoxypropylene polymers in the mixture is between about 900 to about 25,000 and the oxyethylene groups constitute between about 10 to about 90 weight percent of the oxyethylene/oxypropylene mixture. Non-limiting examples of surfactants useful herein having an HLB of about 8 to 18 include: Pluronic� surfactants L10, L43, L44, L63, L64, L65, P75, P84, P85, P103, P104, P105, P123, and mixtures thereof; Reverse Pluronic� surfactants 10R5, 17R4,17R8, 22R4,25R4, 25R5, 25R8, and mixtures thereof; Tetronic� surfactants: 304, 504, 704, 707, 904, 1104, 1304, 1504, and mixtures thereof; and Reverse Tetronic� surfactants 50R4, 50R8, 70R4, 90R8, 110R7150R8, and mixtures thereof; and mixtures thereof.
A volatile and hydrophilic perfume ingredient is characterized by its boiling point ("B.P.") and its octanol/water partition coefficient ("P"). The boiling points of many perfume ingredients are given in, e.g., "Perfume and Flavor Chemicals (Aroma Chemicals)," Steffen Arctander, published by the author, 1969, incorporated herein by reference. The octanol/water partition coefficient of a perfume ingredient is the ratio between its equilibrium concentrations in octanol and in water. Since the partition coefficients of the preferred perfume ingredients have high values, they are more conveniently given in the form of their logarithm to the base 10, logP. LogP values which are calculated are referred to as "CLogP". ClogP values are readily calculated from a program called "CLOGP" which is available from Daylight Chemical Information Systems, Inc., Irvine Calif. Octanol/water partition coefficients are described in detail in U.S. Pat. No. 5,578,563, to Trinh, issued Nov. 26, 1996, incorporated herein by reference in its entirety. The preferred perfume ingredients have a B.P., determined at the normal, standard pressure of about 760 mm Hg, of about 260� C. or lower, preferably less than about 250� C., and a ClogP or an experimental logP, of less than about 3.5, and preferably of less than about 3.0.
Some of the hydrophilic, volatile perfume ingredients can optionally be replaced by hydrophilic, residual perfume ingredients. The optional hydrophilic, residual perfume ingredients have a B.P., measured at the normal, standard pressure, higher than about 260� C., and an experimental logP or ClogP of less than about 3.5. Thus, when a perfume composition is composed of some preferred hydrophilic, volatile ingredients and some hydrophilic, residual ingredients, the perfume effect is longer lasting when the product is used. Non-limiting examples of optional hydrophilic, residual perfume ingredients, useful herein are amyl benzoate, benzophenone, dihydro isojasmonate, isoeugenol, methyl cinnamate, methyl dihydrojasmonate, beta-methyl naphthyl ketone, 2-methoxy naphthalene, delta-nonalactone, vanillin, yara-yara, and mixtures thereof.
Preferred water-soluble preservatives include the following: sodium hydroxymethylglycinate (i.e. Suttocide� A., from Sutton Labs Chatham, N.J.), cyclic organic nitrogen compounds including imidazolidinedione compounds (such as dimethyloldimethylhydantoin i.e., Glydant� Plus from Lonza, Fair Lawn, N.J., diazolidinyl urea and imidazolidinyl urea) and polymethoxy bicyclic oxazolidine; phenyl and phenoxy compounds including benzyl alcohol, 2-phenoxyethanol and hexamidine isethionate; quaternary ammonium compounds including polyhexamethylene biguanide; low molecular weight aldehydes including formaldehyde and glutaraldehyde; halogenated compounds including chlorhexidine, chlorobutanol, and dibromopropamidine; and mixtures thereof.
The compositions may be prepared by oil-in-water emulsion techniques such as are commonly known in the art. Examples of such techniques are described in Remington's Pharmaceutical Science, Eighteenth Edition, pp. 304-306, 1990, incorporated herein by reference. The present compositions also may be prepared by a process comprising the steps of: Making a mixture by mixing a surfactant(s) and an oil phase until homogenous and adding an aqueous phase with mixing until the mixture is homogenous. Making a perfume mixture by mixing the first mixture with a perfume composition (alternatively the perfume composition could be added and mixed during the making of the first mixture). Making a solution by adding cyclodextrin with an aqueous phase with mixing until the cyclodextrin dissolves. Making a second mixture by mixing the solution with the perfume composition until the second mixture is homogenous. Where desired, the second mixture may be diluted by adding an aqueous phase with mixing until homogenous. Where hydrophobic antimicrobials also comprise the compositions, the process of making the mixture in the first step additionally comprises adding a premix with mixing to the surfactant(s) and the oil phase until homogenous, wherein the premix is prepared by mixing a hydrophobic antimicrobial with a surfactant(s) until the premix is homogenous. The term "homogenous", as used herein, means a uniformly dispersed solution. Homogeneity is indicated by a substantially smooth, lump-free and uniform appearing composition. A stable emulsion remains homogeneous over a given period which is determined by the required shelf life of the composition.
As an alternative to making the mixture by mixing a surfactant(s), an oil phase, and an aqueous phase; an emulsion concentrate comprising a surfactant(s), an oil phase, and a minimal amount of aqueous carrier may be used. Emulsion concentrates useful in the present invention will be from about a 3-fold to about a 20-fold concentrate. The concentrated emulsion may then be diluted by adding aqueous carrier followed by addition of the remaining ingredients as discussed above. A suitable method of forming an emulsion concentrate is described in U.S. Pat. No. 5,043,155, to Puchalski et. al, issued Aug. 27, 1991. An example of an emulsion concentrate useful in the present invention is Dow Corning� 365, 35% Dimethicone Emulsion.

Prepare Examples I-III as follows: Prepare a premix by mixing triclosan with about 1/6, by weight, of total Pluronic� L and/or Silwet� L (Example III only). Prepare a first mixture by mixing about 1% of water, by total formula weight, with a perfume and surfactant(s). For Example III, preparing the first mixture also includes a final step of adding the premix with mixing. Using a sonifier, prepare a second mixture by adding dimethicone to the first mixture, then slowly adding about 1%-2% of water, by total formula weight. Prepare premix (a) by mixing hydroxypropyl beta cyclodextrin and about 1.5%-3% of water, by total formula weight; premix (b) by mixing zinc phenolsulfonate and about 2% of water, by total formula weight; premix (c) by mixing the ascorbic acid and about 2% of water by total formula weight; and premix (d) by mixing Glydant� Plus (and Suttocide� A) and propylene glycol. Using a homogenizer, add remaining water to the second mixture to create a third mixture. Add premixes (a), (b), (c), and (d) to the third mixture using the homogenizer.
A man is cooking fish and a spicy sauce requiring the dicing of garlic, onions, and various peppers. He is told that his hands and hair smell of these food odors and he wants to remove these odors from his body. The man rubs his hands and hair with wipes containing the composition in Example I. Each wipe deposits about 0.05 grams of environmental odor-absorbing composition on the skin and hair. The man notices less odor after using the wipes.
A woman finds that after she smokes a cigarette during a break at work, her hands and face smell of smoke and tobacco. She applies the composition from Example II via a hand-held trigger-spray bottle. (She deposits about 2.0 grams of environmental odor-absorbing composition on the skin). She sprays the composition on her face and hands and the composition removes the residual smoke and tobacco odors which she found so disagreeable. This woman notices less odor and feels more comfortable returning to her desk after using the spray.
A man, on his way to an important meeting, stops to buy gasoline for his car. As he is filing the gas tank, gasoline splashes on his hands. The man wipes his hands on a paper towel but the gasoline odor remains on his hands. The man removes a small bottle from his gym bag which contains the composition of Example III. He opens the bottle and pours some of the composition on his hands, delivering roughly about 0.5 grams of the environmental odor-absorbing composition. He then smells his hands and notices that the gasoline odor is no longer present.
