Few of these compositions as they exist in the art are believed to provide deodorization to treated garments, textiles or fibrous substrates.
In a first aspect the present invention provides a sprayable deodorizing composition useful for treating a fibrous substrate, especially textiles and/or garments, comprising the following constituents : a detersive surfactant, preferably being at least one nonionic surfactant; an organic solvent; a deodorant constituent; and water.
The inventive compositions optionally, but in some cases desirably include one or more optional constituents selected from: chelating agents, light stabilizers, fragrances, fragrance solubilizers, thickening agents, hydrotropes, pH adjusting agents, pH buffers, builders, further non-aqueous solvents, optical brighteners, enzymes, preservatives (i.e., germicides, fungicides), corrosion inhibitors, antistatic agents as well as other conventional additives which may be known to the textile arts.
In a further aspect of the invention there is provided a sprayable deodorizing composition useful for treating a fibrous substrate, especially textiles and/or garments, which is provided in a manually pumpable non- pressurized container. According to a still further example of the invention, there is provided a sprayable deodorizing composition useful for treating a fibrous substrate, especially textiles and/or garments, which is provided in a pressurized canister.
A further aspect of the invention provided herein is a process for deodorizing garments, textiles, upholstery and the like by applying a odor-diminishing effective amount of the compositions being described herein. The inventive compositions include at least one detersive surfactant . Exemplary detersive surfactants include anionic, nonionic, cationic, amphoteric and zwitterionic surfactants but are preferably nonionic surfactants. Suitable nonionic surfactants include, inter alia, condensation products of alkylene oxide groups with an organic hydrophobic compound, such as an aliphatic compound or with an alkyl aromatic compound. The nonionic surfactants generally are the condensation products of an organic aliphatic or alkyl aromatic hydrophobic compound and hydrophilic ethylene oxide groups.
One example of such a nonionic surfactant is the condensation product of one mole of an alkyl phenol having an alkyl group containing from 6 to 12 carbon atoms with from about 5 to 25 moles of an alkylene oxide. Another example of such a nonionic surfactant is the condensation product of one mole of an aliphatic alcohol which may be a primary, secondary or tertiary alcohol having from 6 to 18 carbon atoms with from 1 to about 18 moles of alkylene oxide. Preferred alkylene oxides are ethylene oxides or propylene oxides which may be present singly, or may be both present. Preferred nonionic surfactants include primary and secondary linear and branched alcohol ethoxylates, such as those based on Cs to C24 alcohols which further include an average of from 1 to 18 moles of ethoxylation per mol of alcohol . Particularly preferred nonionic surfactants are Cπ linear primary alcohol ethoxylates averaging about 9 moles of ethylene oxide per mole of alcohol . These surfactants are available, for example, in the NEODOL series, (from Shell Chemical Company, Houston, TX) , or in the GENAPOL series of linear alcohol ethoxylates (from Clariant Corp., Charlotte, NC) . A further class of nonionic surfactants which are advantageously present in the inventive compositions are those presently marketed under the GENAPOL tradename, especially those marketed in the "26-L" series such as GENAPOL 26-L-80 and GENAPOL 26-L-60.
Preferred surfactants are those which leave little or no residue subsequent to drying on a garment or textile. The inventive compositions include one or more organic solvents. Exemplary organic solvents which may be included in the inventive compositions include those which are at least partially water-miscible such as alcohols (particularly Cι-C8 primary, secondary, and tertiary alcohols, i.a., n-propanol, isopropanol) , glycols (such as Ci-Cβ glycols), water-miscible ethers (e.g. diethylene glycol diethylether, diethylene glycol dimethylether, propylene glycol dimethylether) , water- miscible glycol ether (e.g. propylene glycol monomethylether, propylene glycol mono ethylether, propylene glycol monopropylether, propylene glycol monobutylether, ethylene glycol monobutylether, dipropylene glycol monomethylether, diethyleneglycol monobutylether) , lower esters of monoalkylethers of ethyleneglycol or propylene glycol (e.g. propylene glycol monomethyl ether acetate) all commercially available such as from Union Carbide (Danbury, CT) , Dow Chemical Co.
(Midland, MI) or Hoescht (Germany) . Mixtures of several organic solvents can also be used.
Preferred as solvents in this invention are the glycol ethers having the general structure Ra-0-Rb-OH, wherein Ra is an alkoxy of 1 to 20 carbon atoms, or aryloxy of at least 6 carbon atoms, and Rb is an ether condensate of propylene glycol and/or ethylene glycol having from one to ten glycol monomer units . Preferred are glycol ethers having one to five glycol monomer units. These are C3-C2o glycol ethers. Examples of more preferred solvents include propylene glycol methyl ether, dipropylene glycol methyl ether, tripropylene glycol methyl ether, propylene glycol isobutyl ether, ethylene glycol methyl ether, ethylene glycol ethyl ether, ethylene glycol butyl ether, diethylene glycol phenyl ether, propylene glycol phenol ether, and mixtures thereof . Particularly preferred organic solvents are described in the Examples.
The inventive compositions include a deodorant constituent, which contains both an aldehyde chosen from one class, (hereinafter called class A) , and an aldehyde chosen from another class, (hereinafter called class B) . This combination has remarkable deodorant properties, clearly superior to those of each of these compounds taken individually.
The deodorant constituent is characterized in that it contains a first aldehyde chosen from acyclic and non- terpenic aliphatic aldehydes, non-terpenic alicyclic aldehydes, terpenic aldehydes, aliphaticaldehydes substituted by an aromatic group and bifunctional aldehydes (class A) and a second aldehyde chosen from aldehydes possessing a non-aromatic unsaturation carried by the carbon in the alpha position of the aldehyde function, aldehydes possessing an unsaturation in the alpha position of the aldehyde function conjugated with an aromatic ring and aldehydes of which the function is carried by an aromatic ring (class B) .
The acyclic and non-terpenic aliphatic aldehydes are preferably selected from: decanal, undecanal, dodecanal, undecene-10-al, 2-methyl-undecanal, 2, 6, 10-trimethyl-9- undecene-al (ADOXAL) and 2, 3, 5, 5-tetramethyl-hexanal .

The terpenic aldehydes are preferably: citronellal 3, 7-dimethyl-6-octen-1-al and campholenic aldehyde.
The aliphatic aldehydes substituted by an aromatic group are preferably: helional® . alpha . -methyl-3 , 4-methylene-dioxyhydrocinnamic aldehyde, cyclamen aldehyde, lilial, canthoxal, phenylacetic aldehyde, 3-phenyl-propionic aldehyde and hydratropic aldehyde .
By "bifunctional aldehyde" is meant aldehydes possessing moreover another function such as the ether- oxide or alcohol functions, preferably: alkoxy- acetaldehydes, w-hydroxy aldehydes (e.g., hydroxycitronellal, LYRALR) and w-alkoxy-aldehydes . The above aldehydes form class A. Among the aldehydes of class B, the aldehydes which possess a non-aromatic type unsaturation carried by the carbon in the alpha position of the aldehyde function are preferably: citral (neral and geranial) , myrtenal, perilla aldehyde and variously substituted 2-furyl carboxaldehydes .
The aldehydes which possess an ethylene unsaturation in the alpha position, itself conjugated with an aromatic ring are preferably: cinnamic aldehyde, alpha- amylcinnamic aldehyde (JASMONAL) or 2-pentyl-3-phenyl-2- propenal and alpha-hexylcinnamic aldehyde.
The aldehydes carried by an aromatic ring, moreover variously substituted, are preferably: benzaldehyde, anisic aldehyde, heliotropine, veratric aldehyde, vanillin, isovanillin, and ethylvanillin. The deodorant compositions according to the present invention contain at least one aldehyde from each of the class A and class B. It is contemplated that three or more aldehydes may be present, with the proviso that at least one aldehyde of each of the two above classes are present .
In the preferred conditions for implementing the invention described above, the first aldehyde (class A) is chosen preferably from the acyclic and non-terpenic aliphatic aldehydes, the alicyclic and non-terpenic aldehydes, the terpenic aldehydes, and the aliphatic aldehydes substituted by an aromatic group, the second aldehyde is preferably chosen from the aldehydes which possess a non-aromatic type unsaturation carried by the alpha carbon.
More preferably, the class A aldehyde is chosen from the acyclic and non-terpenic aliphatic aldehydes and the class B aldehyde from those designated above.
Particularly interesting aldehyde pairs are notably the following pairs: dodecanal and myrtenal; dodecanal and citral; adoxal and Perilla aldehyde; triplal and citral; maceal and citral; adoxal and myrtenal; decanal and citral; and undecene-10-al and myrtenal; as well as the product pairs cited in the examples, below.
The aldehydes of classes A and B can be in relative proportions one to the other and preferably in proportions from 80/20 to 20/80, notably in proportions of 50/50.
The deodorant compositions above, in addition to their remarkable deodorant properties possess, moreover, fragrant properties themselves capable of replacing bad odours by their own smell . The preferred compositions contain in addition a masking agent . Therefore these compositions can be composed of at least one fragrant agent of agreeable smell such as those usually used in the perfume industry such as alcohols, essential oils, phenol substances and esters .
These deodorant compositions find their use in all conditions where the combating of bad smells, whatever their origin, is sought. These deodorant compositions are advantageously formulated according to standard techniques . These aldehydes and methods for their production are described more fully in US 5795566, the contents of which are herein incorporated by reference. The compositions are largely aqueous in nature, and comprise water as a further necessary constituent. Water is added in order to provide to 100% by weight of the compositions of the invention. The water may be tap water, but is preferably distilled and is most preferably deionized water.
The inventive compositions optionally include one or more optional constituents . Exemplary optional constituents include: chelating agents, light stabilizers, fragrances, fragrance solubilizers, thickening agents, hydrotropes, pH adjusting agents, pH buffers, builders, further non-aqueous solvents, optical brighteners, enzymes, preservatives (i.e., germicides, fungicides) , corrosion inhibitors, antistatic agents as well as other conventional additives which may be known to the textile arts .
Generally these one or more optical constituents are added in only minor amounts, i.e., the total of which is not to exceed 10%wt. of the composition of which it forms a part, more preferably not to exceed 8%wt., still more preferably not more than 5%wt.
As a further optional constituent there may be advantageously included a preservative constituent. As a significant portion of the formulation comprises water, it is preferable that the preservative be water soluble. Such water soluble preservatives include compositions which include parabens, including methyl parabens and ethyl parabens, glutaraldehyde, formaldehyde, 2-bromo-2- nitropropane-1, 3-diol , 5-chloro-2-methyl-4-isothiazolin- 3-one, 2-methyl-4-isothiazoline-3-one, and mixtures thereof. One exemplary composition is a combination of 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4- isothiazolin-3-one where the amount of either component may be present in the mixture anywhere from 0.001 to 99.99 weight percent, based on the total amount of the preservative. An exemplary commercially available preservative comprising a mixture of 5-chloro-2-methyl-4- isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one marketed under the trademark KATHON CG/ICP (ex. Rohm and Haas ) as well as KATHON CG/ICP II, (ex.. Rohm and Haas) SUTTOCIDE A (ex. Sutton Laboratories) TEXTAMER 38AD (ex. Calgon Corp.) as well as PROXEL GXL (ex. Zeneca Biocides) described as being 1, 2-benzisothiazolin-3-ene (17%wt.) and inert ingredients (83%wt.) . A useful and preferred preservative is DANTOGUARD PLUS (ex.Lonza) which is described as being 1,3 di- (hydroxymethyl) -5, 5- dimethylhydantoin and 3-iodo-2-propynl butyl carbamate. The preferred preservative has been observed to exhibit good compatibility with the other constituents in accordance with preferred embodiments of the inventive compositions. The compositions may include a fragrance constituent which is to be understood as including any water soluble or non-water soluble fragrance substance or mixture of such substances which are intended to impart a desirable scent characteristic. Such fragrances include those which are naturally derived (i.e., obtained by extraction of flower, herb, blossom or plant) , those which are artificially derived or produced (i.e., mixture of natural oils and/or oil constituents) , and those which are synthetically produced substances (odiferous substances) . Generally perfumes are complex mixtures or blends various organic compounds including, but not limited to, certain alcohols, aldehydes, ethers, alamatic compounds and varying amounts of essential oils such as from about 0 to about 85% by weight, usually from about 10 to about 70% by weight, the essential oils themselves being volatile odiferous compounds and also functioning to aid in the dissolution of the other components of the perfume .
The inclusion of a known art fragrance solubilizer which assists in the dispersion, solution or mixing of the deodorizing constituent in an aqueous base is frequently preferred. These include known art compounds, including condensates of 2 to 30 moles of ethylene oxide with sorbitan mono- and tri-Cι0-C2o alkanoic acid which are also known to be useful as nonionic surfactants. Further examples of such suitable surfactants include water soluble nonionic surfactants of which many are commercially known and by way of non-limiting example include the primary aliphatic alcohol ethoxylates, secondary aliphatic alcohol ethoxylates, alkylphenol ethoxylates and ethylene-oxide-propylene oxide condensates on primary alkanols, and condensates of ethylene oxide with sorbitan fatty acid esters . These fragrance solubilizers may be in addition to the detersive surfactant constituent mentioned above. It is recognized that the detersive constituent may be effective as a fragrance solubilizer itself. This fragrance solubilizer component is added in minor amounts, particularly amounts which are found effective in aiding in the solubilization of the fragrance component, such that it would be considered as a detergent constituent. Such minor amounts recited herein are generally up to about 0.3% by weight of the total composition but are more generally an amount of about 0.1% by weight and less, and preferably present in amounts of about 0.05% by weight and less.
The compositions according to the invention optionally but desirably include an amount of a pH adjusting agent or pH buffer composition. Such compositions include many which are known to the art and which are conventionally used. By way of non-limiting example pH adjusting agents include phosphor containing compounds, monovalent and polyvalent salts such as of silicates, carbonates, and borates, certain acids and bases, tartrates and certain acetates. Further useful pH adjusting agents include acids and bases, particularly organic and inorganic acids which might be useful to lower the alkalinity of the compositions. Exemplary useful inorganic acids include hydrochloric acid, while exemplary useful organic acids include the free acid forms of mono- and polycarboxylic acids, such as citric acid, glycolic acid, and free acid forms of aminopolycarboxylic acids such as ethylenediaminetetraacetic acid. Free acid forms of such aminopolycarboxylic acids, especially those of ethylenediaminetetraacetic acid are particularly preferred as the inclusion of this acid may provide acidity to a formulation, and at the same time may complement the efficacy of the aminopolycarboxylic acid salts which are required to be present in the inventive compositions. Certain particularly preferred embodiments of the invention include both aminopolycarboxylic acid salts and the corresponding aminopolycarboxylic acid in free acid form.
By way of further non-limiting examples, pH buffering compositions include the alkali metal phosphates, polyphosphates, pyrophosphates, triphosphates, tetraphosphates, silicates, metasilicates, polysilicates, carbonates, hydroxides, and mixtures of the same. Certain salts, such as the alkaline earth phosphates, carbonates, and hydroxides, can also function as buffers. It may also be suitable to use as buffers such materials as aluminosilicates (zeolites) , borates, aluminates and certain organic materials such as gluconates, succinates, maleates, and their alkali metal salts. Particularly useful are carbonates, which are included in preferred embodiments of the invention.
Exemplary optical brighteners include those based on stilbene compounds and derivatives.
Exemplary enzymes include proteases, amylases, lipases and others known in the detergent art.
Exemplary useful corrosion inhibitors, which are preferably included when the inventive compositions are provided in a pressurized canister, particularly steel canisters, include sodium nitrite and sodium benzoate. The inventive compositions may be produced by simply mixing the required constituents while stirring in order to produce a homogenous composition. Preferably however, the deodorant constituent is first solubilized in the detersive surfactant and/or the fragrance solubilizer (i.e, sorbitan monooleate) , further optionally with water, to form a premixture, which premixture is then added to the remaining constituents while stirring in order to produce the compositions.
Fibrous substrates which can be treated in accordance with this invention are textile fibers or filaments, and finished or fabricated fibrous articles such as textiles, and garments. The textiles include those made of natural fibers, such as cotton and wool, as well as those made of synthetic organic fibers, such as nylon, polyolefin, acetate, rayon, acrylic and polyester fibers.
The inventive compositions by be used to treat fibrous substrates, including textiles such as: clothing, (shirts, blouses, pants, slacks, suits, sweaters, coats, jackets, vests and the like, as well as clothing accessories such as ties, hats, gloves, and the like) garments, linens, bedding, sheets, pillowcases, curtains, draperies, upholstery covers, and the like. These textiles may be stale-smelling due to odors such as tobacco smoke, residue, perfume, and perspiration. Such fibrous substrates and other textiles are treated by dispensing a odor-diminishing effective amount of the sprayable compositions being described herein.
The compositions of this invention may be packaged in any suitable container, such as an unpressurized bottle or in a pressurized container. According to one aspect of the invention, the compositions are provided a sprayable textile garment deodorizing composition which is provided in a manually pumpable non-pressurized container. By way of non-limiting example, such includes a container portion typically made of synthetic polymer plastic material such as polyethylene, polypropylene, polyvinyl chloride or the like and further includes a spray nozzle, a dip tube and associated pump dispensing parts. The composition is dispensed from the non- pressurized container by the consumer whom manually operates the pump, which dispenses the composition to the surface of a fibrous substrate, i.a., a textile, garment, etc.
According to a still further example of the invention, there is provided an aerosolized sprayable textile garment deodorizing composition which is provided in a pressurized canister.
The compositions of the invention are supplied in a pressurized delivery canister from which they may be directly dispensed onto fibrous substrates, including those described above. The compositions are pressurized and by means of the addition of a suitable propellant to the composition. Any propellant which can self-pressurize the composition and serve as the means for dispensing it from its container is suitable, including compressed gases such as nitrogen or carbon dioxide. The preferred propellants are liquified, normally gaseous propellants such as the known hydrocarbon and halogenated hydrocarbon propellants . The preferred normally gaseous hydrocarbon propellants include the aliphatic saturated hydrocarbons such as propane, butane, isobutane, and isopentane; halogenated hydrocarbons include chlorodifluoromethane, difluoroethane dichlorodifluoromethane and the like. Mixtures of two or more propellants can be used. The propellant is desirably utilized in an amount sufficient to expel the entire contents of the containers . In general, the propellant will be from about 5% to about 25%, preferably about 5% to about 15%, still more preferably from about 5% to about 10% by weight of the total composition.
The following examples illustrate the superior properties of the formulations of the invention and particular preferred embodiments of the inventive compositions . The terms "parts by weight" or "percentage weight" as well as "%wt." are used interchangeably in the specification and in the following Examples wherein the weight percentages of each of the individual constituents are indicated in weight percent based on the total weight of the composition, unless indicated otherwise.
Examples : Exemplary formulations illustrating certain preferred embodiments of the inventive compositions and described in more detail below were formulated generally in accordance with the following protocol .
Into a suitably sized vessel, a measured amount of water was provided after which the constituents were added in no specific or uniform sequence, which indicated that the order of addition of the constituents was not critical . All of the constituents were supplied at room temperature, and any remaining amount of water was added thereafter. Certain of the nonionic surfactants, if gelled at room temperature, were first preheated to render them readily pourable liquids prior to addition and mixing. Mixing of the constituents was achieved by the use of a mechanical stirrer with a small diameter propeller at the end of its rotating shaft. Mixing, which generally lasted from 5 minutes to 120 minutes was maintained until the particular exemplary formulation appeared to be homogeneous .
