Description

FIELD OF THE INVENTION [0001] The present invention relates to a perfume composition comprising a malodor-binding polymer and a malodor control component.

The present invention relates to a blue-sensitive composition comprising a malodor-binding polymer, a malodor control component and an aqueous carrier, and a method thereof.

[0004] Background of the Invention [0005] [0002] Cigarette products for reducing or shielding odors in cloth and in the air are now available and described in the patent literature. The Procter & Gamble Company sells fabrics and air-conditioning products under the trademark FEBREZE (R). These products typically contain fragrances, solubilizers, cyclodextrins and aqueous carriers. s. Seed. S. C. Johnson sells products such as Glade < (R) > fabric and air deodorant, Oust < (R) > surface disinfectant and air disinfectant. Reckitt-Benckiser sells products such as Lysol (R) disinfectant spray.

Certain orienting compositions do not effectively neutralize a wide range of odors in the fabric and in the air. In addition, the time required for the composition to stand out against the odor can create consumer suspicions about the efficacy of the product against the odor. For example, the consumer may leave the processing space before the product begins to noticeably reduce the odor.

There remains a need for an improved perfume composition that neutralizes a wide range of odors, including odors caused by amine and sulfur scavengers and microorganisms, without overpowering the odor with an overwhelming fragrance.

The present invention relates to a chewing composition for odor reduction. According to one embodiment, an effective amount of a malodor binding polymer; An odor control component comprising an effective amount of a mixture of two or more volatile aldehydes to neutralize the odor; And an aqueous carrier, wherein the two or more volatile aldehydes are selected from the group consisting of 2-ethoxybenzylaldehyde, 2-isopropyl-5-methyl-2-hexenyl, 5- methylpurfural, (4E) -4 (5-methyl-thiophene-carboxaldehyde, azotoxal, p-anisaldehyde, benzylaldehyde, bourgeonal, cinnamic aldehyde, cymal, decylaldehyde, , 8-dimethyldeca-4,9-dienyl), florhydral, heliolal, lauric aldehyde, ligustral, laural, melonalle, o-anisaldehyde (2- methoxybenzaldehyde) Is selected from the group consisting of aldehyde, pyridine (PT) bidentate, thiophenecarboxaldehyde, trans-4-decaneal, trans-trans 2,4-nonadienal, undecylaldehyde and mixtures thereof.

In another embodiment, an effective amount of a malodor binding polymer; And an odor control component comprising an acid catalyst having a vapor pressure at 25 DEG C of from about 0.01 torr to about 13 torr and at least one volatile aldehyde.

The present invention also relates to a method for reducing odor, comprising the steps of: providing an elegant composition comprising an effective amount of a malodor-binding polymer and a malodor control component; And dispersing the effective amount of the textural composition on an inanimate surface or in the air.

Figure 5 is a graph showing the reduction of butanethiol by thiophenecarboxaldehyde in combination with various acid catalysts.

The inventive compositions are designed not to function by delivering true odor reduction and simply by masking or masking the odor using a fragrance. The present compositions reduce the odor on the air or on inanimate surfaces, for example, on food fabrics contaminated with environmental odors such as food and tobacco odors or on sweat-damp cloth. The present compositions may also reduce microorganisms on inanimate surfaces or in the air. The present compositions may also serve as barriers to prevent the odor from adhering to the inanimate surface or from penetrating the inanimate surface.

True odor reduction provides sensory and analytically measurable (for example, gas chromatograph) odor reduction. Thus, when the blue composition delivers true odor reduction, the blue composition will neutralize the odor in the air and / or on the fabric. As used herein, "neutralize" or "neutralize" means a chemical reaction with a malodor component (e.g., a primary amine reacts with an aldehyde to form an imine, a reductive alkylation of the amine, And deprotonation, polymerization or depolymerization); Or to reduce the volatility of the odoriferous components, allowing other parts of the composition to react (e.g., acid-base neutralization); Or physically capturing odorous molecules, such that the molecules are not re-released into the air (e. G., Cyclodextrin inclusion complexes as described herein). In contrast to changes in the ability to sense odor without any corresponding change in the state of the odor compounds, odor neutralization can be distinguished from odor shielding or odor shielding in that the odor compounds change.

D. polyamino acid

Suitable amine-based compounds include polyamino acids. Polyamino acids are composed of amino acids or chemically modified amino acids. Amino acids are selected from cysteine, histidine, isoleucine, tyrosine, tryptophan, leucine, lysine, glutamic acid, glutamine, glycine, alanine, aspartic acid, arginine, asparagine, phenylalanine, proline, serine, histidine, threonine, methionine, . Amino acid derivatives include tyrosine ethylate, glycine methylate, tryptophan ethylate, or mixtures thereof; Homopolymers of amino acids; Hydroxyamine; Polyamino acids; Or a mixture thereof.

In chemically modified amino acids, amines or acidic functionalities of amino acids have reacted with chemical reagents. This is often done to protect these chemical amines and acidic functionalities of the amino acids in subsequent reactions or to provide amino acid-specific properties, such as improved solubility. Examples of such chemical modifications include benzyloxycarbonyl, aminobutyric acid, butyl esters, and pyroglutamic acid. Additional examples of general modifications of amino acids and small amino acid fragments can be found in Bachem, 1996, Peptides and Biochemicals Catalog.

One polyamino acid is polylysine, alternatively polylysine or polyamino acid wherein more than 50% of the amino acids are lysine, since the primary amine functionality in the side chain of the lysine is the most reactive amine of all amino acids Because. The molecular weight of one polyamino acid is from 500 to 10,000,000, alternatively from 2000 to 25,000.

The polyamino acid can be cross-linked. Crosslinking can be obtained, for example, by condensation of an amino group in the side chain of an amino acid such as lysine with a protein cross-linking agent such as a carboxyl function or PEG derivative of said amino acid. Cross-linked polyamino acids still need to have free primary and / or secondary amino groups left for neutralization. The molecular weight of the crosslinked polyamino acid is 20,000 to 10,000,000; Alternatively from 200,000 to 2,000,000.

The polyamino acids or amino acids may be copolymerized with other reagents such as, for example, acids, amides, acyl chlorides, aminocapric acid, adipic acid, ethylhexanoic acid, caprolactam or mixtures thereof. The molar ratios used in these copolymers range from 1: 1 (reagent / amino acid (lysine)) to 1:20, alternatively from 1: 1 to 1:10. Polyamino acids, such as polylysine, can be non-ethoxylated or partially ethoxylated as long as the required amount of primary amine remains in the polymer.

Monopolymeric PEI is a branched, spherical polyamine, which has a clear ratio of primary, secondary and tertiary amine functionalities. This is best illustrated by the following structural formula: < RTI ID = 0.0 >

The chemical structure of monopolymeric PEI follows a simple principle: one amine functional entity - two carbons.

The blue-sensitive composition preferably has a molecular weight of from about 800 to about 2,000,000, alternatively from about 1,000 to about 2,000,000, alternatively from about 1,200 to about 25,000, alternatively from about 1,300 to about 25,000, alternatively from about 2,000 to about 25,000, From about 10,000 to about 2,000,000, alternatively from about 25,000 to about 2,000,000, alternatively about 25,000. Exemplary homopolymeric PEIs include those commercially available from BASF under the trade name Lupasol (R). Lupazol products are generally obtained through polymerization of ethyleneimine monomers. Ethyleneimine monomers were completely reacted in the polymer matrix.

In one embodiment, the malodor binding polymer can be used in an amount effective to provide a reduction in microorganisms in the cloth and / or in the air. When using a malodor binding polymer, an effective amount reduces microorganisms by a difference of at least 1 log as compared to a composition lacking a malodor binding polymer. This difference, therefore, is due to the use of odor-binding polymers and is not due to inherent variability of microbial species.

A suitable level of the odor-binding polymer is from about 0.01% to about 2%, alternatively from about 0.01% to about 1%, alternatively from about 0.01% to about 0.8%, alternatively from about 0.01% To about 0.6%, alternatively from about 0.01% to about 0.1%, alternatively from about 0.01% to about 0.07%, alternatively from about 0.07%. Compositions with a higher amount of odor-binding polymer may be susceptible to transient stains and / or leave unacceptable visible stains on the fabric as the solution evaporates from the fabric.

B. Odor Control Component

The present conditioning composition may comprise a malodor control component. The odor control component is designed to achieve true odor neutralization and not function by simply covering or shielding the odor. True odor neutralization provides a sensible and analytically measurable (eg, gas chromatograph) odor reduction. Thus, when the odor control component achieves true odor neutralization, the composition will reduce the odor in the vapor phase and / or the liquid phase. When used in combination with an odor-binding polymer, the composition can cause a substance that neutralizes a wider range of odors, which further reduces odors on the air or inanimate surface.

1. Fragrance material

The odor control component comprises a perfume material which may comprise a mixture of volatile aldehydes. Volatile aldehydes neutralize odors in vapor phase and / or liquid phase through chemical reactions. Partially volatile aldehydes can be considered to be volatile aldehydes, as used herein. Volatile aldehydes can react with amine-based odors along the Schiff-base formation pathway. The volatile aldehydes can also react with the sulfur odor to form thiol acetals, hemithiol acetals and thiol esters in the vapor phase and / or the liquid phase. These vapor phase and / or liquid phase volatile aldehydes may desirably not have a substantially negative impact on the desired fragrance characteristics of the product.

The vapor pressure (VP) of a suitable volatile aldehyde may range from about 0.013 Pa (100 Torr) to about 13,332.2 Pa (100 Torr), alternatively from about 0.013 Pa (0.0001 Torr) to about 1033 Torr ), Alternatively from about 0.001 torr to about 50 torr, alternatively from about 0.001 torr to about 20 torr, alternatively from about 0.0033 torr to about 0.0033 torr, (0.100 torr), alternatively from about 0.133 Pa to about 0.06 torr, alternatively from about 0.001 torr to about 4.00 Pa (0.03 torr), alternatively from about 0.67 torr Alternatively from about 0.01 Torr to about 20 Torr, alternatively from about 0.01 Torr to about 15 Torr, from about 0.05 Torr to about 20 Torr, ), Alternatively from about 0.01 Torr to about 10 Torr, alternatively from about 0.05 Torr to about 10 Torr.

The volatile aldehyde may also have a predetermined boiling point (B.P.) and an octanol / water partition coefficient (P). The boiling point referred to herein is measured under normal standard pressure of 101.3 kPa (760 mmHg). The boiling point of a number of volatile aldehydes at a standard 101.3 kPa (760 mmHg) is given, for example, in Perfume and Flavor Chemicals (Aroma Chemicals), written and published by Steffen Arctander, 1969.

The octanol / water partition coefficient of volatile aldehydes is the ratio between its equilibrium concentration in octanol and its equilibrium concentration in water. The partition coefficient of the volatile aldehyde used in the odor control component can be given more conveniently in the form of a logarithm of log 10, logP. The logP values of many volatile aldehydes have been reported. See, for example, the Pomona 92 database available from Daylight Chemical Information Systems, Inc., Daylight CIS, Irvine, CA. However, the logP value is most conveniently calculated with the "CLOGP" program also available from Daylight Cites. The program also lists experimental log P values when available in the Pomona 92 database. The calculated log P (Clog P) is determined by Hansch and Leo's fragment approach (see A. Leo, in Comprehensive Medicinal Chemistry, Vol. 4, C. Hansch, PG Sammens, JB Taylor and Ramsden, Eds., 295, Pergamon Press, 1990). The fragment approach is based on the chemical structure of each volatile aldehyde, taking into account the number and type of atoms, atomic connectivity and chemical bonding. The ClogP value, which is the most reliable and widely used evaluation of the physicochemical properties, is preferably used in place of the experimental logP value in the selection of the volatile aldehyde of the malodor control component.

ClogP values may be defined by four groups, and volatile aldehydes may be selected from one or more of these groups. The first group includes volatile aldehydes having a B.P. of about 250 캜 or less and a ClogP of about 3 or less. The second group includes volatile aldehydes having a B.P. of 250 캜 or lower and a ClogP of 3.0 or higher. Group 3 includes volatile aldehydes with a B.P. of 250 ° C or higher and a ClogP of 3.0 or lower. Group 4 includes volatile aldehydes with a B.P. of at least 250 캜 and a ClogP of at least 3.0. The odor control component may comprise any combination of volatile aldehydes from one or more ClogP groups.

In some embodiments, the malodor control component of the present invention comprises from about 0% to about 30% volatile aldehyde from the first group, alternatively from about 25%, based on the total weight of the malodor control component; And / or from about 0% to about 10% volatile aldehyde from the second group, alternatively from about 10%; And / or from about 10% to about 30%, alternatively from about 30%, of volatile aldehydes from the third group; And / or from about 35% to about 60%, alternatively about 35%, of volatile aldehydes from the fourth group.

In certain embodiments, the volatile aldehyde is present in an amount of up to 100%, alternatively from 1% to about 100%, alternatively from about 2% to about 100%, alternatively from about 3% to about 100% , Alternatively from about 50% to about 100%, alternatively from about 70% to about 100%, alternatively from about 80% to about 100%, alternatively from about 1% to about 20% Alternatively from about 3% to about 20%, alternatively from about 4% to about 20%, alternatively from about 5% to about 20%, alternatively from about 1% to about 10%, alternatively from about 2% %. ≪ / RTI >

In some embodiments, where volatility is not critical to odor neutralization, the present invention may include poly-aldehydes, such as di-, tri, tetra-aldehydes. This embodiment may include laundry detergents, additives, etc. for applications such as leave-on, through the wash and rinse-off type.

In one embodiment, the conditioning composition comprises a perfume mixture having one or more cloth-safe, non-yellowing aliphatic aldehydes. Certain types of aldehydes predominantly comprising straight chain aliphatic skeletons will not discolor the fabric unlike products in which the type of aldehyde containing multiple double bonds and benzene rings is utilized. The following table illustrates the choice of aldehyde to avoid transparency.

An example of a suitable aliphatic aldehyde is R-COH, where R is saturated linear and / or branched C ₇ to C _{22 with up} to two double bonds. Examples of suitable aliphatic aldehydes include but are not limited to bourgeoisole, citral, citronellyloxyacetaldehyde, sinal, decylaldehyde, heliolane, hexyl cinnamic aldehyde, lauric aldehyde, ligustral, laural, There may be mentioned hydrozamonate, methylnonylacetaldehyde, methylphenylcarvinyl acetate, nonylaldehyde, octylaldehyde, oxalic acid, PTbushnal, polyacidol, lubafuran, triafal or mixtures thereof.

In one embodiment, the composition comprises at least one aliphatic aldehyde selected from the group consisting of: bourgeoisole, citral, citronellyloxyacetaldehyde, sinal, decylaldehyde, heliolal, hexylcinnamic But are not limited to, aldehyde, lauric aldehyde, ligustral, lauryl, melonol, methyldihydrozazomonate, methylnonyl acetaldehyde, methylphenylcarvinyl acetate, nonylaldehyde, Aldehyde, oxane, Biscuit, polyanthol, luobafuran, triacryl, and mixtures thereof.

In another embodiment, the composition comprises at least one aliphatic aldehyde selected from the group consisting of: boucheonate, sime, hexyl cinnamic aldehyde, methyl dihydrozazomonate, methylnoylacetaldehyde, .tea. Bush and mixtures thereof.

The aliphatic aldehyde may be present in an amount of from about 0.001% to about 10%, alternatively from about 0.001% to about 5%, alternatively from about 0.01% to about 1%, alternatively from about 0.02% to about 1% Alternatively from about 0.02% to about 0.5%, alternatively from about 0.02% to about 0.06%, alternatively from about 0.06%.

In addition to the aliphatic aldehydes, the compositions may also include fragrance materials, including fragrances, ketones, ionone alpha, ionone beta, ionones including gamma methyl gamma, or mixtures thereof, for its fragrance experience. Suitable fragrance materials are discussed in U.S. Patent No. 5,714,137. The composition may contain an amount of perfume effective to provide a greasy aroma when initially sprayed, some subsequent perfume, and some extra perfume that is released upon topsoil wetting. It may be desirable that the aliphatic aldehyde does not have a substantially negative impact on the desired fragrance characteristics.

Certain odor counteractants are odorous and can negatively affect the overall properties of the fragrance. In this case, a fragrance / odor counteractant premix is formed such that the fragrance raw material used is selected to neutralize any odor of the odor counteractant. This odor neutralized premix can then be added to the moisturizer mixture without affecting the properties of the emulsion. This allows odor counteractants to be used extensively in a wide variety of fragrance types.

The following is a non-limiting example of a perfume formulation comprising a cloth-safe odor counteractant.

In some cases, the laundered fabric will remain with a brightener that is deposited from the detergent to wash the fabric. It may therefore be desirable for the aliphatic aldehyde to be compatible with the brightener so that the blue-sensitive composition does not discolor any cloth to which it comes in contact. Many of the above examples are compatible with brighteners.

2. Fragrance delivery system

The odor control component may comprise a perfume delivery system. A consumer choosing and using such directional products makes a critical decision on how satisfied the product is at a number of touch points within the product usage profile. Although a number of contacts are known, Applicants have found that contacts can be advantageously grouped and typically expressed as the moment of truth of the three products that the consumer experiences.

FMOT is typically at the point of purchase, SMOT typically begins with the application and use of the product, and TMOT typically begins shortly after application and use of the product. The Applicant has found that the consumer's FMOT is negatively affected because product packaging hinders sensory experience, for example, because product packaging can make product opening difficult or expose spillable products when opened. . In addition, the formulation components can suppress and / or distort the odor of pure product. Moreover, Applicants have recognized that the consumer's SMOT is negatively affected because the volatile perfume feedstock is lost during product storage and the bloom is reduced during use. Compensating for the aforementioned deficiencies by adding high fragrance levels to the TMOT can distort the perfume experience during use, so that the perfume bloom aroma can be too harsh, strong and / or directional less desirable. The Applicant has also found that the FMOT of the consumer is negatively affected by the long-term treatment of fragrance, especially the fragrance release from the drying cloth, during the first and second critical moments, I was aware that I was affected. Moreover, the addition of high fragrance levels in SMOT and TMOT can distort the odor of the pure product and still not lead to sufficient fragrance deposition during cleaning. In addition, the fragrance evaporation that occurs during drying can degrade the level of the fragrance on the fabric and / or the fragrance remaining on the drying cloth may provide an initial dry cloth odor effect, but such fragrance is too fast to provide sufficient fragrance persistence . Moreover, the fragrance present on the fabric can be released too slowly from the fabric. As mentioned, this may be the same as in the case of perfume delivery to other sites such as hair and skin and perfume release from this location. The ability to perceive fragrance release can be influenced by a variety of factors, such as hair length, clothing worn on the skin, frequency of situs wash, and the like. Moreover, the fragrance strength and / or characteristics may be perceived differently on the wetted area as compared to the dried area treated with the fragrance containing product. Without wishing to be bound by theory, in addition to the loss of the fragrance by evaporation during drying, the fragrance may be made less available at a given contact by being transported into or divided into areas such as cotton fibers, hair, skin, and the like. The site moisture level can also serve to alter the release profile or release rate of the fragrance.

Finally, Applicants have found that a solution to the problem associated with one or two critical moments may be insufficient to solve the problem associated with the remaining crucial moment (s), or may adversely affect other crucial moment (s) .

The following perfume delivery technology (PDT), also known as a perfume delivery system, can be used in any combination in any type of consumer product:

a. Polymer Assisted Delivery (PAD)

These PDTs use polymeric materials for delivery of the fragrance material. Liquid crystalline, hot melt, hydrogel, directional plastic, microcapsule, nano- and micro-latex, polymeric film formers such as, for example, conventional coacervation, water soluble or partially soluble to insoluble charged or neutral polymers, liquid crystals, hot melts, hydrogels, , And polymeric absorbents, polymeric adsorbents, and the like. The PAD includes, but is not limited to:

Matrix system: The perfume is dissolved or dispersed in the polymer matrix or particles. The perfume can be dispersed in the polymer, for example, 1) before it is formulated into the product, or 2) separately from the polymer during formulation of the product or after formulation of the product. The diffusion of the fragrance from the polymer is a common trigger that increases the fragrance release rate from the polymeric matrix system that is deposited or applied to the desired surface (area), or allows this release, but many other triggers Lt; / RTI > Absorption and / or adsorption into or onto polymer particles, films, solutions, etc. is an aspect of the technology. Examples are nano- or micro-particles composed of organic materials (e.g. latex). Suitable particles are selected from the group consisting of polyacetals, polyacrylates, polyacrylics, polyacrylonitriles, polyamides, polyaryl ether ketones, polybutadiene, polybutylene, polybutylene terephthalate, polychloroprene, polyethylene, polyethylene terephthalate, Polycarbonate, polycyclohexylene dimethylene terephthalate, polycarbonate, polychloroprene, polyhydroxyalkanoate, polyketone, polyester, polyethylene, polyetherimide, polyethersulfone, polyethylene chlorinate, polyimide, polyisoprene , Polylactic acid, polymethylpentene, polyphenylene oxide, polyphenylene sulfide, polyphthalamide, polypropylene, polystyrene, polysulfone, polyvinyl acetate, polyvinyl chloride, acrylonitrile-butadiene, cellulose acetate, Ethylene-vinyl acetate, ethylene ratio Alcohols, styrene and a polymer or a copolymer of ethylene and mixtures thereof as a substrate, but includes a wide range of material, but not limited-butadiene, vinyl acetate.

A "standard" system refers to a preloaded fragrance up to fragrance release moments or moments that are "preloaded " with the intention of continually being associated with the polymer. Such polymers can also suppress the odor of pure product and provide a bloom and / or sustained effect depending on the fragrance release rate. One challenge in this system is 1) to achieve an ideal balance between stability in the product (holding the fragrance inside the carrier until needed) and 2) timely release (during use or from the drying site). The achievement of this stability is particularly important during storage and product aging in the product. Such difficulties are particularly apparent in aqueous based surfactant-containing products, for example heavy duty liquid laundry detergents. Many "standard" matrix systems that are effectively available become "balanced" systems when formulated as aqueous based products. A "balanced" system or storage system with available triggers for release (such as friction) and acceptable diffusion stability in products can be selected.

A "balanced" system is one in which the perfume and polymer can be added separately to the product and the equilibrium interaction between the perfume and the polymer (in contrast to a free perfume control without polymer assisted delivery technology) will be. Also, the polymer can be pre-loaded with a fragrance, but some or all of the fragrance can diffuse and reach equilibrium during storage in the product, including having the desired perfume raw material (PRM) associated with the polymer. The polymer then carries the perfume to the surface, and the release is typically through perfume diffusion. The use of such a balanced system polymer has the potential to reduce the intrinsic product odor intensity of pure products (generally more so for pre-loaded standard systems). The deposition of such polymers can serve to "planarize " the release profile and provide increased persistence. As indicated above, this persistence will be achieved by suppressing the initial strength, and may result in more high impact or lower odor detection threshold (ODT) to achieve the FMOT effect without too strong or distorted initial strength or It may be possible to use the PRM of the lower Kovats Index (KI) by the preparer. Fragrance emissions are important to occur within the application period to affect the desired consumer contacts or contacts. Suitable microparticles and micro-latexes, and methods for their preparation, can be found in U.S. Patent Publication No. 2005/0003980 Al. The matrix system also includes hot melt adhesive and directional plastic. In addition, hydrophobically modified polysaccharides may be formulated into orientable products to increase perfume deposition and / or alter perfume release. For example, all such matrix systems, including polysaccharides and nano latexes, can be combined with other PDTs including other PAD systems such as perfume microcapsule (PMC) type PAD storage systems. The PAD matrix system may include those described in the following references: U.S. Patent Publication No. 2004/0110648 A1; U.S. Patent Publication No. 2004/0092414 A1; U.S. Patent Publication No. 2004/0091445 A1 and U.S. Patent Publication No. 2004/0087476 A1; U.S. Patent No. 6,531,444; U.S. Patent No. 6,024,943; U.S. Patent No. 6,042,792; U.S. Patent No. 6,051,540; U.S. Patent No. 4,540,721 and U.S. Patent No. 4,973,422.

Silicon is also an example of a polymer that can be used as a PDT, which can provide a perfume effect in a manner similar to a polymeric assisted delivery "matrix system ". This PDT is referred to as silicone-assisted delivery (SAD). Preloading the fragrance to the silicon or using silicon as a balancing system is as described for PAD. Suitable silicones and their preparation are described in International Patent Publication Nos. WO 2005/102261; U.S. Patent Publication No. 20050124530A1; U.S. Patent Publication No. 20050143282A1; And International Patent Publication No. WO 2003/015736. Functionalized silicon may also be used, as described in U.S. Patent Publication No. 2006/003913 Al. Examples of silicon include polydimethylsiloxane and polyalkyldimethylsiloxane. Other examples include those having amine functionalities, which include the effects associated with amine-assisted delivery (AAD) and / or polymer assisted transfer (PAD) and / or amine-reaction product (ARP) ≪ / RTI > Other examples include U.S. Patent No. 4,911,852; U.S. Patent Publication No. 2004/0058845 A1; U.S. Patent Publication No. 2004/0092425 A1 and U.S. Patent Publication No. 2005/0003980 A1.

Storage system: The storage system is also known as a core-shell type technology, or is surrounded by a fragrance release control membrane that can serve as a protective shell. The material inside the microcapsule is called the core, the internal phase, or the filler, while the wall is sometimes referred to as a shell, coating or membrane. Microparticles or pressure sensitive capsules or microcapsules are examples of such techniques. The microcapsules of the present invention are formed by a variety of procedures including, but not limited to, coating, extrusion, spray-drying, interfacial, home position and matrix polymerization. Possible shell materials vary widely in their stability to water. Amongst the most stable are polyoxymethylene urea (PMU) -based materials, which can hold a desired PRM in an aqueous solution (or product) even for a long period of time. Such systems include, but are not limited to urea-formaldehyde and / or melamine-formaldehyde. Gelatin-based microcapsules can be prepared such that the capsules are rapidly or slowly dissolved in water, for example, depending on the degree of cross-linking. Many other capsule wall materials are available, which vary in the degree of perfume stability observed. Without wishing to be bound by theory, for example, once it is deposited on a surface, the rate of release of the fragrance from the capsule is typically the inverse of the fragrance diffusion stability in the product. Thus, for example, urea-formaldehyde and melamine-formaldehyde microcapsules are typically found in the presence of mechanical forces (e.g., friction, pressure, shear stress) that act to break the capsule and increase the rate of perfume release Likewise, a release mechanism other than or in addition to diffusion for release is required. Other triggers include melting, dissolving, hydrolyzing or other chemical reactions, electromagnetic radiation, and the like. The use of preloaded microcapsules requires adequate stability of the product as well as proper selection of PRM and appropriate ratio of release on the surface and / or on the surface. Microcapsules based on urea-formaldehyde and / or melamine-formaldehyde are relatively stable, especially in the near neutral aqueous-based solution. These materials may require a friction trigger that may not be applicable to all product applications. Other microcapsule materials (e.g., gelatin) may be unstable in aqueous-based products and may even provide reduced effectiveness when compared to free-perfume controls when aged in the product. Scratch and sniff techniques are another example of PAD. Perfume microcapsules (PMC) may include those described in the following references: U.S. Patent Publication No. 2003/0125222 A1; U.S. Patent Application Publication 2003/215417 A1; U.S. Patent Application Publication 2003/216488 A1; U.S. Patent Application Publication 2003/158344 A1; U.S. Patent Application Publication 2003/165692 A1; U.S. Patent Publication No. 2004/071742 Al; U.S. Patent Publication No. 2004/071746 Al; U.S. Patent Publication No. 2004/072719 A1; U.S. Patent Application Publication 2004/072720 A1; U.S. Patent Application Publication 2006/0039934 A1; U.S. Patent Application Publication 2003/203829 A1; U.S. Patent Application Publication 2003/195133 A1; U.S. Patent Application Publication 2004/087477 A1; U.S. Patent Publication No. 2004/0106536 A1; And U.S. Patent No. 6,645,479 B1; U.S. Patent No. 6,200,949 B1; U.S. Patent No. 4,882,220; U.S. Patent No. 4,917,920; U.S. Patent No. 4,514,461; U.S. Patent No. 6,106,875 and U.S. Patent No. 4,234,627, U.S. Patent No. 3,594,328, and U.S. Reissue Patent No. 32713.

b. Molecule-Assisted Delivery (MAD)

Non-polymeric materials or molecules may also play a role in enhancing the delivery of the fragrance. Without wishing to be bound by theory, the perfume may non-covalently interact with the organic material, leading to altered deposition and / or release. Non-limiting examples of such organic materials include hydrophobic materials such as organic oils, waxes, mineral oils, petroleum jelly, fatty acids or esters, sugars, surfactants, liposomes and even other fragrance ingredients (fragrances) soil, and the like, but are not limited thereto. Directional fixation is another example. In one embodiment, the CLogP of the non-polymeric material or molecule is greater than about 2. MAD may also include those described in U.S. Patent No. 7,119,060 and U.S. Patent No. 5,506,201.

c. Fiber-assisted delivery (FAD)

The selection or use of the site itself may serve to enhance the delivery of the fragrance. In practice, the region itself may be a perfume delivery technology. For example, different cloth types, such as cotton or polyester, will have different properties with respect to their ability to attract and / or hold and / or release the fragrance. The amount of fragrance deposited on or in the fibers can be varied not only by any fiber coating or treatment, but also by fiber selection, and also by the history or processing of the fibers. The fibers may be natural or synthetic fibers as well as woven and nonwoven fibers. Natural fibers include those produced by plant, animal and geological processes and include fibers used in the manufacture of cellulosic materials such as cotton, linen, hemp jute, flax, ramie, and sisal, paper and cloth But is not limited thereto. The FAD may be made of wood fibers, such as thermomechanical pulp and the use of bleached or non-bleached kraft or sulfite pulp. Animal fibers are mainly composed of certain proteins, such as silk, guns, joists and fur (including wool). The polymeric fibers based on synthetic chemicals may be selected from the group consisting of polyamide nylon, PET or PBT polyesters, phenol-formaldehyde (PF), polyvinyl alcohol fibers (PVOH), polyvinyl chloride fibers (PVC), polyolefins (PP and PE) , And acrylic polymers. All such fibers may be pre-loaded with a perfume, which may then be added to the product, which may or may not contain free fragrance and / or one or more perfume delivery techniques. In one embodiment, the fibers are added to the product before the fragrance is loaded, and then the fragrance can be loaded into the fiber by adding a fragrance to the product that can diffuse into the fiber. Without wishing to be bound by theory, the fragrance can be absorbed or adsorbed onto the fiber, for example during product storage, and subsequently released at one or more critical moments or consumer contacts.

d. Amine Supplemental Delivery (AAD)

The amine-assisted delivery technology approach utilizes materials that contain amine groups to increase perfume deposit during product use or to change fragrance release. In this approach, there is no requirement for pre-complexing or pre-reacting the fragrance raw material (s) and amine prior to addition to the product. In one embodiment, the amine-containing AAD material suitable for use in the present invention is non-aromatic; For example, a polyalkylimine such as PEI, or PVam, or an aromatic, such as anthranilate. Such materials may also be polymeric or non-polymeric. In one embodiment, this material contains at least one primary amine. This technique is not limited by theory, and it is believed that the delivery of other PRMs via polymer-assisted delivery to polymeric amines and the controlled release of low ODT fragrance fractions (e. G., Aldehydes, ketones, enones) And increased persistence. Without the technique, the volatile top note is lost too quickly, so that the ratio of the middle note and the base to the upward can become even greater. The use of polymeric amines allows higher levels of uptake and other PRMs to be used, or upwards and other PRMs to be used more efficiently, so that the smell of pure product is not stronger than desired, while the continuity of freshness is obtained. In one aspect, the AAD system is effective at delivering the PRM at a pH that is approximately greater than neutral. Without wishing to be bound by theory, the conditions under which more amines in the AAD system are deprotonated may result in increased affinity of deprotonated amines for PRM, such as ketones and aldehydes, including unsaturated ketones and enones, such as damascone . In another aspect, polymeric amines are effective to deliver PRM at a pH that is less than about neutral. Without wishing to be bound by theory, it is believed that the conditions under which more amines in the AAD system are protonated reduce the affinity of the protonated amines for PRM, such as aldehydes and ketones, and the stronger of the polymer framework for a broader range of PRMs It can bring about affinity. In this aspect, polymer-assisted delivery can deliver more perfume effects, and such a system can be termed an amine-polymer-assisted delivery (APAD) or sub-species of AAD. In some cases where APAD is used in a composition having a pH of less than 7, such an APAD system may also be considered a polymer assisted delivery (PAD). In another embodiment, the AAD and PAD systems can interact with other materials, such as anionic surfactants or polymers to form coacervate and / or coacervate-like systems. In another embodiment, a material containing a heteroatom other than nitrogen, such as sulfur, phosphorus, or selenium, may be used as an alternative to the amine compound. In another embodiment, the above-described alternative compounds can be used in combination with an amine compound. In another embodiment, a single molecule can comprise an amine moiety and one or more alternative heteroatom moieties, such as thiol, phosphine, and selenol. Suitable AAD systems and methods of making them are described in U.S. Patent Publication No. 2005/0003980 A1; U.S. Patent Application Publication 2003/0199422 A1; U.S. Patent Application Publication 2003/0036489 A1; U.S. Patent Publication No. 2004/0220074 A1 and U.S. Patent No. 6,103,678.

e. Starch encapsulation accord ( Starch Encapsulated Accord ; SEA )

The use of starch encapsulation accord (SEA) technology alters the properties of the fragrance by, for example, converting liquid fragrances into solids by the addition of ingredients such as starch. The effect includes increased fragrance retention during product storage, especially under non-aqueous conditions. Upon exposure to moisture, the fragrance bloom can be triggered. Effects at other critical moments can also be achieved because the starch allows the product formulator to select PRM or PRM concentrations that are not normally available without the presence of SEA. Another example of technology involves the conversion of fragrances from liquid to solids using other organic and inorganic materials, such as silica. Suitable SEAs and methods for their preparation can be found in U.S. Patent Publication No. 2005/0003980 A1 and U.S. Patent No. 6,458,754 B1.

f. Zeolite and Inorganic Carrier (ZIC)

This technique relates to the delivery of fragrances using porous zeolites or other inorganic materials. Perfume-loaded zeolite (PLZ) can be used, for example, with auxiliary ingredients used to coat the fragrance-loaded zeolite (PLZ) to change its fragrance release properties during or during use, Can be used without the auxiliary component. Suitable zeolites and inorganic carriers and their preparation are disclosed in U.S. Patent Publication No. 2005/0003980 A1 and U.S. Patent No. 5,858,959; U.S. Patent No. 6,245,732 B1; U.S. Patent No. 6,048,830 and U.S. Patent No. 4,539,135. Silica is another form of ZIC. Another example of a suitable inorganic carrier includes inorganic tubules, wherein the fragrance or other active material is contained within the lumen of the nanotracer or microtubule. Preferably, the perfume-loaded inorganic tubule (or Perfume-Loaded Tubule or PLT) is a mineral microtubule or microtubule, such as haloysite or halosite and other clays, / RTI > PLT techniques may also include additional ingredients on the interior and / or exterior of the tubules to control diffusion stability in the article, deposition on the desired site, or to control the rate of release of the loaded fragrance. Monomer and / or polymeric materials comprising starch encapsulation may be used to coat, plug, cap, or otherwise encapsulate PLT. Suitable PLT systems and methods for their preparation can be found in U.S. Patent No. 5,651,976.

g. Pro-Perfume (PP)

This technique refers to a perfume technology resulting from the reaction of a perfume material with another substrate or chemical to form a material having a covalent bond between one or more PRMs and one or more carriers. PRM is converted to a new substance called pro-PRM (i.e., pro-aroma), which can then release the original PRM upon exposure to a trigger such as water or light. PP can provide enhanced fragrance delivery properties such as increased fragrance deposition, persistence, stability, retention, and the like. The PP can be preformed, including monomeric (non-polymeric) or polymeric, or it can be formed in situ under equilibrium conditions such as during storage in a product or on a wet or dry site . Non-limiting examples of PP include Michael adducts (e. G., Beta-aminoketones), aromatic or non-aromatic amines (Schiff bases), oxazolidines, beta-keto esters, and ortho esters . Another aspect includes compounds comprising one or more beta-oxy or beta-thiocarbonyl moieties capable of releasing PRM, such as alpha, beta-unsaturated ketones, aldehydes or carboxylic acid esters. Exemplary triggers for the release of the fragrance are exposure to water, but other triggers may include enzymes, heat, light, pH changes, autoxidation, shift of equilibrium, changes in concentration or ionic strength, and others. For aqueous based products, pro-aromatizing agents that are photo triggered are particularly suitable. Such photo-pro-perfumes (PPPs) include, but are not limited to, releasing coumarin derivatives and fragrances and / or pro-fragrances upon triggering. The released PP may release one or more PRMs by any of the triggers mentioned above. In one aspect, the PPP emits a nitrogen-based PP when exposed to light and / or moisture triggers. In another embodiment, the nitrogen-based PP released from the PPP releases one or more PRMs selected from, for example, aldehydes, ketones (including enones), and alcohols. In another embodiment, PPP releases a dihydroxy coumarin derivative. The photo-triggering pro-fragrance may also be an ester which emits a directional alcohol and a coumarin derivative. In one embodiment, the pro-perfume is a dimethoxybenzoin derivative, as described in U.S. Patent Publication No. 2006/0020459 Al. In yet another embodiment, the PP is a 3 ', 5 ' -dimethoxy benzoin (DMB) derivative that releases an alcohol upon exposure to electromagnetic radiation. In another embodiment, the pro-aroma releases at least one low ODT PRM comprising a tertiary alcohol such as linalool, tetrahydrolinalol or dihydromayherenol. Suitable pro-fragrances and methods for their preparation are described in U.S. Patent Nos. 7,018,978 B2; U.S. Patent No. 6,987,084 B2; U.S. Patent No. 6,956,013 B2; U.S. Patent No. 6,861,402 B1; U.S. Patent No. 6,544,945 B1; U.S. Patent No. 6,093,691; U.S. Patent No. 6,277,796 B1; U.S. Patent No. 6,165,953; U. S. Patent No. 6,316, 397 B1; U.S. Patent No. 6,437,150 B1; U.S. Patent No. 6,479,682 B1; U.S. Patent No. 6,096,918; U. S. Patent No. 6,218, 355 B1; U.S. Patent No. 6,133,228; U.S. Patent No. 6,147,037; U.S. Patent No. 7,109,153 B2; U.S. Patent No. 7,071,151 B2; U.S. Patent No. 6,987,084 B2; U.S. Patent No. 6,610,646 B2 and U.S. Patent No. 5,958,870, and in addition, U.S. Patent Publication No. 2005/0003980 A1 and U.S. Patent Application Publication No. 2006/0223726 Al.

Amine Reaction Product (ARP): For purposes of this application, ARP is a subclass or species of PP. "Reactive" polymeric amines in which the amine functionality reacts with one or more PRMs to form amine reaction products (ARP) can also be used. Typically, the reactive amine is a primary and / or secondary amine and may be part of a polymer or monomer (non-polymer). This ARP can also be combined with additional PRM to provide the effect of polymer-assisted delivery and / or amine-assisted delivery. Non-limiting examples of polymeric amines include polymers based on polyalkylimines, such as PEI, or PVam. Non-limiting examples of monomeric (non-polymeric) amines include hydroxylamines, such as 2-aminoethanol and alkyl substituted derivatives thereof, and aromatic amines such as anthranilate. The ARP may be added separately in the rib-on or rinse-off application, or premixed with the perfume. In another embodiment, a material containing a heteroatom other than nitrogen, such as oxygen, sulfur, phosphorus, or selenium, may be used as an alternative to the amine compound. In another embodiment, the above-described alternative compounds can be used in combination with an amine compound. In another embodiment, a single molecule may comprise an amine moiety and one or more alternative heteroatom moieties, such as thiol, phosphine, and selenol. The effect may include controlled delivery of the fragrance as well as improved delivery of the fragrance. Suitable ARPs and methods for their preparation can be found in U.S. Patent Publication No. 2005/0003980 A1 and U.S. Patent No. 6,413,920 B1.

3. Low molecular weight polyol

In addition to the perfume material, the odor control component is a low molecular weight polyol having a relatively high boiling point (relative to water) such as ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, dipropylene glycol and / . Such polyols can improve the odor neutralization of the composition of the present invention. Some polyols, such as dipropylene glycol, are also useful to facilitate solubilization of some fragrance components in the compositions of the present invention.

The glycols used in the composition of the present invention may be glycerin, ethylene glycol, propylene glycol, dipropylene glycol, polyethylene glycol, propylene glycol methyl ether, propylene glycol phenyl ether, propylene glycol methyl ether acetate, propylene glycol n-butyl ether, butyl ether, dipropylene glycol n-propyl ether, ethylene glycol phenyl ether, diethylene glycol n-butyl ether, dipropylene glycol n-butyl ether, diethylene glycol monobutyl ether, dipropylene glycol methyl ether, Methyl ether, tripropylene glycol n-butyl ether, other glycol ethers, or mixtures thereof. In one embodiment, the glycol used is ethylene glycol, propylene glycol, or mixtures thereof. In another embodiment, the glycol used is diethylene glycol.

Typically, the low molecular weight polyol is present in the composition of the present invention at a level of from about 0.01% to about 5%, alternatively from about 0.05% to about 1%, alternatively from about 0.1% To about 0.5%. A composition with a higher concentration may be susceptible to transient stains and / or leave unacceptable visible stains on the fabric as the solution evaporates from the fabric. The weight ratio of the low molecular weight polyol to the malodor binding polymer is from about 500: 1 to about 4: 1, alternatively from about 1: 100 to about 25: 1, alternatively from about 1: 50 to about 4: 4: 1.

4. Cyclodextrin

In some embodiments, the blue-sensitive composition may comprise a solubilized, water-soluble, non-complexed cyclodextrin. The term "cyclodextrin " as used herein refers to any of the known cyclodextrins, such as unsubstituted cyclodextrins, including 6 to 12 glucose units, especially alpha-cyclodextrin, beta-cyclodextrin, gamma- Dextrin and / or derivatives thereof and / or mixtures thereof. Alpha-cyclodextrin consists of six glucose units, beta-cyclodextrin consists of seven glucose units, and gamma-cyclodextrin consists of eight glucose units arranged in a donut-shaped ring. Certain coupling and incorporation of glucose units provides the cyclodextrin with a rigid, conical molecular structure with the desired non-vesicular hollow interior. The "alignment" of the inner cavity is formed by a hydrogen atom and a glycosidic bridging oxygen atom, and thus the surface is quite hydrophobic. The unique shape and physico-chemical properties of the cavity enable the cyclodextrin molecule to absorb (form an entrapping complex with these molecules) of organic molecules or some organic molecules that can fit within the cavity. Many fragrance molecules can fit into the cavity.

Cyclodextrin molecules are described in U.S. Patent No. 5,714,137 and U.S. Patent No. 5,942,217. A suitable level of cyclodextrin is from about 0.1% to about 5%, alternatively from about 0.2% to about 4%, alternatively from about 0.3% to about 3%, alternatively from about 0.4% About 2%. A higher concentration of the eucalyptus composition may result in transient stains and / or leave unacceptable visible stains on the fabric as the solution evaporates from the fabric. The latter is particularly problematic on thin, colored synthetic fabrics. To avoid or minimize the occurrence of cloth stains, the fabric may be treated with a level of cyclodextrin of less than about 5 mg per 1000 mg, alternatively less than about 2 mg per 1000 mg of cyclodextrin.

5. Acid catalyst

The odor control component of the present invention can contain an effective amount of an acid catalyst to neutralize the sulfur odor. Certain weak acids have been found to affect the reactivity of the aldehyde with the thiol in the liquid phase and vapor phase. The reaction between the thiol and the aldehyde was found to be a catalytic reaction following the mechanism of the hemiacetal and acetal formation pathways. When the odor control component of the present invention contains an acid catalyst and contacts the sulfur odor, the volatile aldehyde reacts with the thiol. This reaction can form a thiol acetal compound and thereby neutralize the sulfur odor. Without the acid catalyst, only hemi-thiol acetal is formed.

Suitable VPs of the acid catalysts may range from about 0.133 Pa (about 0.001 torr) to about 5,066.2 Pa (38 torr), alternatively from about 0.133 Pa (0.001 torr) to about 0.133 Pa (as measured by the Scifinder) Alternatively from about 0.133 to about 133.3, alternatively from about 0.133 to about 2.67, alternatively from about 0.67 to about 2.67 Pa (0.001 to about 1, alternatively from about 0.001 to about 0.020, Alternatively from about 0.005 to about 0.020, alternatively from about 0.010 to about 0.020 torr).

The acid catalyst may be a weak acid. The weak acid is characterized by the acid dissociation constant, K _a , the equilibrium constant for dissociation of the weak acid _; pKa is the negative logarithm of the logarithm of K _{a .} The pKa of the acid catalyst may be from about 4.0 to about 6.0, alternatively from about 4.3 to 5.7, alternatively from about 4.5 to about 5, alternatively from about 4.7 to about 4.9. Suitable acid catalysts include those listed in Table 4.

[Table 4]

Depending on the desired use of the odor control component, the influence on the aroma of the odor control component or the aroma characteristics can be considered when selecting the acid catalyst. In some embodiments of the odor control component, it may be desirable to select an acid catalyst that provides a neutral to pleasant aroma. The VP of such an acid catalyst may range from about 0.133 Pa (0.001 torr) to about 2.67 Pa (0.020 torr), alternatively from about 0.005 torr to about 2.67 Pa (0.020 torr), alternatively (0.010 torr) to about 2.67 Pa (0.020 torr). Non-limiting examples of such acid catalysts include 5-methylthiophenecarboxaldehyde including benzoic acid, succinic acid, or carboxylic acid impurities.

The malodor control component may comprise from about 0.05% to about 5%, alternatively from about 0.1% to about 1.0%, alternatively from about 0.1% to about 0.5%, alternatively from about 0.1% to about 0.5% 0.4%, alternatively about 0.4%, of the acid catalyst.

In the acetic acid system, the odor control component of the present invention may comprise about 0.4% acetic acid (50:50 TC: DPM, 0.4% acetic acid).

Odor shielding may include compounds that do not disagree or have a pleasant odor that are administered to limit the ability to sense malodorous compounds. Odor shielding can include selection of compounds in harmony with the odor expected to change the overall aroma sensation provided by the combination of odorous compounds.

The odor control component may optionally also include a fragrance ingredient that alone provides hedonic benefit (i.e., provides a pleasant odor that does not neutralize the odor). Suitable fragrances are disclosed in U.S. Patent No. 6,248,135, incorporated herein by reference in its entirety.

For example, the odor control component may comprise a mixture of volatile aldehydes that neutralize the diluent, the fragrance, the ionone, and the odor. Alternatively, the odor control component may comprise 100% volatile aldehyde.

Table 6 shows a non-limiting example of an elegant composition according to the present invention.

[Table 6]

Formulations VI, VII, and VIII in Table 6 are prepared and compared to Control Formulation V, a composition that does not contain a malodor binding polymer for its effect on odor. Figure 1 shows that when the odor-binding polymer is included in the blue-sensitive composition according to the present invention, the aldehyde odor evaporates on the treated cloth.

Fill the sample with odor of interest. For grease infusion, place 226.8 grams (8 ounces) of grease in the Presto ™ electric skillet and cover the skilllet lid. Put the skillet in a 113.6-liter (30-gallon) metal garbage can. Pass the electrical cord from the skillet through the 3.8 cm (1.5 inch) hole in the trash can. Heat the skilllet to 121 ° C and equilibrate it for 15 minutes. Remove the lid. Suspend 20.3 cm (8 inches) x 20.3 cm (8 inches) of cloth sample from the metal clip on a rotating round carousel in the trash can lid. When measured from the base of the specimen, the distance to the top of the skilllet is 20.3 cm (8 inches). Place the lid on the waste bin and manually rotate the rotary circular conveyor at 15 rpm (revolutions per minute) for a period of 40 minutes. After injection, each of the compositions to be tested is sprayed onto the specimen. The spray for each sample is made up of two complete strokes of the trigger sprayer bottle. Keep the bottle at 15.2 cm (6 inches) away from the cloth and place the spray in the center of the cloth. Immediately after treatment, each specimen is cut in half, but each is placed in a vial of 125 mL of top space. Seal the vial. The vial is equilibrated at 100 DEG C for at least 2 hours and then analyzed by sampling each vial using PDMS SPME fiber and analyzed by GC / MS. The malodor component previously identified is then tracked through all samples. The data is aggregated by the total area count of the cumulative area count of the individual peaks.

Microbial reduction

Table 7 shows a non-limiting example of an elegant composition according to the present invention.

[Table 7]

Formulation IX, which is a control formulation without odor-binding polymer, and Formulation X are compared against their effect on microbial reduction. FIG. 2 is a graph showing the ratio of non-toxic to non-toxic bacteria against Staphylococcus aureus (ATCC 6538), Aspergillus niger (ATCC 6275), Proteus mirabilis (ATCC 7002) and Pseudomonas aeruginosa (ATCC 15442) - Results of formulations containing PEI and not containing PEI when tested for the efficacy of the residual gentle microbicide.

Formulation efficacy was assessed using the North American Bactericidal Fabric Spray Test Method, a quantitative modification of the AOAC Germicidal Spray Products Test method (961.02). This method is described in U.S. Pat. EPA Pesticide Assessment Guidelines Subdivision G, Series 91-52 (b) (1). The referenced AOAC method was applied to the fabric surface. (1.5 inches, 100% blue oxford cotton), which can be obtained from Testfabrics Inc., is completely pressed twice with a trigger sprayer bottle containing each formulation Spray. Contact times of 10 to 30 minutes at ambient temperature were selected as conservative time estimates for the sprayed cloth surfaces, as provided in Subdivision G, Series 91-1 (b) (4) (i). Any extra liquid is drained and then transferred to a bottle containing 20 ml of neutralizing agent and / or growth promoting broth. The bottle is vortexed and then sonicated for 5 minutes on a Branson Bransonic Ultrasonic Sonicator. Within 30 minutes of neutralization, the bottles are mixed in a vortex mixer for 2-3 seconds and subsequently diluted. All samples are incubated under appropriate conditions (48 hours 4 hours) and monitored for growth or non-growth. The sample is smoothed and counted to determine the average log10 reduction.

Effects of volatile aldehydes on amine and sulfur odor

Odor standards are prepared by pipetting 1 mL of butylamine (amine odor) and butanethiol (yellow odor) into a 1.2 liter gas sampling bag. The bag is then filled to a constant volume with nitrogen and allowed to stand for at least 12 hours to equilibrate.

A 1 [mu] l sample of each of the volatile aldehydes listed in Table 6 and each of the Accords (A, B, and C) listed in Tables 1 to 3 was pipetted into individual 10 mL silanized headspace vials do. The vial is sealed and equilibrated for at least 12 hours. Repeat 4 times for each sample (twice for butylamine analysis and twice for butanethiol analysis).

After the equilibration period, 1.5 mL of the target odor standard is injected into each vial containing the volatile aldehyde or the Accord sample. For thiol analysis, the sample is held at room temperature for 30 minutes and then injected into the system. 250 μL of each sample is injected into the system for the thiol sample using a 1 mL headspace syringe. For amine analysis, the sample is immediately injected into the system after the odor is introduced. 500 μL of each sample is injected into the system for the amine sample using a 1 mL headspace syringe. Use a GC pillow for amine analysis to shorten the run time. The sample is then analyzed using GC / MS with a DB-5, 20 m, 1 um film thickness column equipped with MPS-2 autosampler equipment with static headspace function. Data is analyzed by ion extraction at each total ion current flow (30 for 56-amine for thiol) and area is used to calculate% reduction from odor standards for each sample.

Table 8 shows the effect of certain volatile aldehydes on the neutralization of amine and sulfur odor at 40 seconds and 30 minutes, respectively.

[Table 8]

Table 9 shows the percent reduction of butylamine and butanethiol at 40 seconds and 30 minutes for Accord A, Accord B and Accord C, respectively.

Remove the fish patty from the frying pan and blot for 10 seconds on the paper towel. The remaining three patties are fried in the same manner. Each fish patty is placed in a 60 x 15 mm petri dish and covered with a lid.

Each petri dish containing a fish patty is introduced into an individual test chamber. The specifications of the test chamber are the same as those in the sulfur (i.e., garlic) odor test. The lid is removed to expose the odor for a residence time (about 1 minute) sufficient to provide an initial odor intensity rating of 70-80. Once the initial odor intensity rating has been reached in the test chamber, the petri dish is removed from the test chamber.

Next, each of the three Notizbles (registered trademark) air conditioning devices sold by P < J > is filled with the control composition outlined in Table 10. Set the device to a low intensity position and plug the plug into three of the four test chambers. All the doors of the chamber are closed.

At 5, 15, 20, 30, 45, and 60 minutes, trained evaluators open each chamber, smell the chamber for odor intensity, and assign odor scores, which are based on the scale in Table 9 do. Between sequential evaluators, the chamber door is closed but not locked. The scores are tabulated and the average score in each time interval is recorded.

The protocol is repeated (using the prototype I shown in Table 10) in three Notices (TM) air conditioning devices (instead of the control composition). The protocol is also repeated using Prototype 2 as shown in Table 11 in three Notewebs (R) air conditioning devices.

Figure 4 shows that formulations with the 10% odor control composition of the present invention reduce the fish odor more than the control without this odor control composition.

Effect of Acid Catalyst on Sulfur Odor

Odor standards are prepared by pipetting 1 mL of butanethiol (sulfur odor) into a 1.2 liter gas sampling bag. The bag is then filled to a constant volume with nitrogen and allowed to stand for at least 12 hours to equilibrate.

A 1 [mu] l aliquot of each of the following samples is pipetted into each 10 mL silanized headspace vials in duplicate. The following samples were analyzed: thiophenecarboxaldehyde as the control, and thiophenecarboxaldehyde, 0.04%, 0.10%, 0.43% in DPM, 1.02% in DPM and 2.04% 50 mixture is pipetted into individual 10 mL silanized headspace vials: phenol, mesitylene acid, caprylic acid, succinic acid, pivalic acid, tiglic acid, and benzoic acid. The vial is sealed and equilibrated for at least 12 hours.

After the equilibration period, 1.5 mL of the target odor standard is injected into each vial containing the volatile aldehyde or the Accord sample. Samples are kept at room temperature for 30 minutes and then injected. The sample is then analyzed using GC / MS with a DB-5, 20 m, 1 탆 film thickness column equipped with an MPS-2 autosampler utilizing static headspace function. 250 [mu] l of each sample is injected into the system using a 1 mL headspace syringe. For the sample, at least two iterations of the odor standard proceed according to each method. Data is analyzed by ion extraction at each total ion current flow (56 for thiol), and area is used to calculate% reduction from odor standards for each acid catalyst sample.

Figure 5 shows that acid catalysts at low vapor pressures provide up to 3 times better sulfur odor reduction compared to the control.
