These surfactants are as-filable for example, in the NEODOL series, (from Shell Chemical Company, Houston. TX), or in the GENAPOL senes 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-L60.

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, esters.

These deodorant compositions find their use in all conditions where the combating of bad smells, whatever their origin, is sought. These deodoran ; compositions are advantageously formulated according to standard techniques. These aidehydes 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 to order to provide to 100% by weight of the compositions of the invention. The water may be tap water, but is preferably distille and is most preferably deionized water.

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 % ut.

As a further optional constituent there may be advantageously included a preservative constituent.

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 functionina 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-CI0-C20 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-oxidepropylene oxide condensates on primary alkanols, and condensates of ethylene oxide with sorbitan fatty acid esters. These fragrance solubilizers ma 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 amount 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 is more generally an amount of about 0.1% by weight and less, and preferably is present in amounts of about 0.05% bv weight and less.

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 acidiry 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 ot the same.

Certain salts, such as the alkaline earth phosphates, carbonates. and hydroxydes 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 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.
