Patent Application
20160296656
The present invention relates to absorbent articles comprising malodor reduction composition and methods of making and using such compositions and absorbent articles.
Unscented or scented products are desired by consumers as they may be considered more natural and discreet than scented products. Manufacturers of unscented or scented products for controlling malodors rely on malodor reduction ingredients or other technologies (e.g. filters) to reduce malodors. However, effectively controlling malodors, for example, amine-based malodors (e.g. fish and urine), thiol and sulfide-based malodors (e.g. garlic and onion), C2-C12 carboxylic acid based malodors (e.g. body and pet odor), indole based malodors (e.g. fecal and bad breath), short chain fatty aldehyde based malodors (e.g. grease) and geosmin based malodors (e.g. mold/mildew) may be difficult, and the time required for a product to noticeably reduce malodors may create consumer doubt as to the product's efficacy on malodors. Often times, manufacturers incorporate scented perfumes to help mask these difficult malodors.
Unfortunately, malodor control technologies typically cover up the malodor with a stronger scent and thus interfere with the scent of the perfumed or unperfumed situs that is treated with the malodor control technology. Thus, limited nature of the current malodor control technologies is extremely constraining. Thus what is needed is a broader palette of malodor control technologies so the perfume community can deliver the desired level of character in a greater number of situations/applications. Surprisingly, Applicants recognized that in addition to blocking a malodor's access to a sensory cell, in order to achieve the desired goal, a malodor control technology must leave such sensor cell open to other molecules, for example scent molecules. Thus, the malodor control technologies disclosed herein do not unduly interfere with the scent of the perfumed or unperfumed situs that is treated with the malodor control technology. Furthermore, Applicants recognized that absorbent articles such as sanitary napkins, panty liners, tampons, inter labial articles, adult incontinence articles, and baby diapers contain a significant quantity of hydrophobic materials and perfume materials are typically, due to manufacturing constraints and/or to avoid contact with other benefit agents, placed on or near such hydrophobic materials. Thus, Applicants discovered that hydrophobic malodor control technology materials are preferable as such materials are generally retained on the subject article longer than typical malodor control technology materials. Applicants disclose such malodor control technology materials and articles comprising same herein.
The present invention relates to an article selected from an absorbent article, polybag or paper carton, said article comprising malodor reduction compositions and methods of making and using such compositions. Such malodor control technologies do not unduly interfere with the scent of the perfumed or unperfumed article that is treated with the malodor control technology.
As used herein “MORV” is the calculated malodor reduction value for a subject material. A material's MORV indicates such material's ability to decrease or even eliminate the perception of one or more malodors. For purposes of the present application, a material's MORV is calculated in accordance with method found in the test methods section of the present application.
The term “absorbent article” is used herein in a very broad sense including any article able to receive and/or absorb and/or contain and/or retain fluids and/or exudates, especially bodily fluids/bodily exudates. Exemplary absorbent articles in the context of the present invention are disposable absorbent articles. The term “disposable” is used herein to describe articles, which are not intended to be laundered or otherwise restored or reused as an article (i.e. they are intended to be discarded after a single use and preferably to be recycled, composted or otherwise disposed of in an environmentally compatible manner). Typical disposable absorbent articles according to the present invention are diapers, surgical and wound dressings, breast and perspiration pads, incontinence pads and pants, bed pads as well as absorbent articles for feminine hygiene like sanitary napkins, panty liners, tampons, interlabial devices or the like. Absorbent articles suitable for use in the present invention include any type of structures, from a single absorbent layer to more complex multi-layer structures. Certain absorbent articles include a fluid pervious topsheet, a backsheet, which may be fluid impervious and/or may be water vapor and/or gas pervious, and an absorbent element comprised there between, often also referred to as “absorbent core” or simply “core”.
The term “Sanitary tissue product” or “tissue product” as used herein means a wiping implement for post-urinary and/or post-bowel movement cleaning (toilet tissue products), for otorhinolaryngological discharges (facial tissue products) and/or multi-functional absorbent and cleaning uses (absorbent towels such as paper towel products and/or wipe products). The sanitary tissue products of the present invention may comprise one or more fibrous structures and/or finished fibrous structures, traditionally, but not necessarily, comprising cellulose fibers.
The term “tissue-towel paper product” refers to products comprising paper tissue or paper towel technology in general, including, but not limited to, conventional felt-pressed or conventional wet-pressed tissue paper, pattern densified tissue paper, starch substrates, and high bulk, uncompacted tissue paper. Non-limiting examples of tissue-towel paper products include towels, facial tissue, bath tissue, table napkins, and the like.
As used herein, “malodor” refers to compounds generally offensive or unpleasant to most people, such as the complex odors associated with bowel movements.
As used herein, “odor blocking” refers to the ability of a compound to dull the human sense of smell.
As used herein, the terms “a” and “an” mean “at least one”.
As used herein, the terms “include”, “includes” and “including” are meant to be non-limiting.
As used herein, the term “perfume” does not include malodor reduction materials. Thus, the perfume portion of a composition does not include, when determining the perfume's composition, any malodor reduction materials found in the composition as such malodor reduction materials are described herein. In short, if a material has a malodor reduction value “MORV” that is within the range of the MORV recited in the subject claim, such material is a malodor reduction material for purposes of such claim.
Unless otherwise noted, all component or composition levels are in reference to the active portion of that component or composition, and are exclusive of impurities, for example, residual solvents or by-products, which may be present in commercially available sources of such components or compositions.
All percentages and ratios are calculated by weight unless otherwise indicated. All percentages and ratios are calculated based on the total composition unless otherwise indicated.
It should be understood that every maximum numerical limitation given throughout this specification includes every lower numerical limitation, as if such lower numerical limitations were expressly written herein. Every minimum numerical limitation given throughout this specification will include every higher numerical limitation, as if such higher numerical limitations were expressly written herein. Every numerical range given throughout this specification will include every narrower numerical range that falls within such broader numerical range, as if such narrower numerical ranges were all expressly written herein.
A non-limiting set of suitable malodor reduction materials are provided in the tables below. For ease of use, each material in Tables 1-3 is assigned a numerical indentifier which is found in the column for each table that is designated Number. Table 4 is a subset of Table 1, Table 5 is a subset of Table 2 and Table 6 is a subset of Table 3 and there for Tables 4, 5 and 6 each use the same numerical identifier as found, respectively, in Tables 1-3.

The saturation Vapour Pressure (VP) values are computed for each PRM in the perfume mixture being tested. The VP of an individual PRM is calculated using the VP Computational Model, version 14.02 (Linux) available from Advanced Chemistry Development Inc. (ACD/Labs) (Toronto, Canada) to provide the VP value at 25° C. expressed in units of torr. The ACD/Labs' Vapor Pressure model is part of the ACD/Labs model suite.
The value of the log of the Octanol/Water Partition Coefficient (log P) is computed for each PRM in the perfume mixture being tested. The log P of an individual PRM is calculated using the Consensus log P Computational Model, version 14.02 (Linux) available from Advanced Chemistry Development Inc. (ACD/Labs) (Toronto, Canada) to provide the unitless log P value. The ACD/Labs' Consensus log P Computational Model is part of the ACD/Labs model suite.
In order to conduct the calculations involved in the computed-value test methods described herein, the starting information required includes the identity, weight percent, and molar percent of each PRM in the perfume being tested, as a proportion of that perfume, wherein all PRMs in the perfume composition are included in the calculations. Additionally for each of those PRMs, the molecular structure, and the values of various computationally-derived molecular descriptors are also required, as determined in accordance with the Test Method for the Generation of Molecular Descriptors described herein.
For each PRM in a perfume mixture or composition, its molecular structure is used to compute various molecular descriptors. The molecular structure is determined by the graphic molecular structure representations provided by the Chemical Abstract Service (“CAS”), a division of the American Chemical Society, Columbus, Ohio, U.S.A. These molecular structures may be obtained from the CAS Chemical Registry System database by looking up the index name or CAS number of each PRM. For PRMs, which at the time of their testing are not yet listed in the CAS Chemical Registry System database, other databases or information sources may be used to determine their structures. For a PRM which has potentially more than one isomer present, the molecular descriptor computations are conducted using the molecular structure of only one of the isomers, which is selected to represent that PRM. The selection of isomer is determined by the relative amount of extension in the molecular structures of the isomers. Of all the isomers of a given PRM, it is the isomer whose molecular structure that is the most prevalent which is the one that is selected to represent that PRM. The structures for other potential isomers of that PRM are excluded from the computations. The molecular structure of the isomer that is the most prevalent is paired with the concentration of that PRM, where the concentration reflects the presence of all the isomers of that PRM that are present.
A molecule editor or molecular sketching software program, such as ChemDraw (CambridgeSoft/PerkinElmer Inc., Waltham, Mass., U.S.A.), is used to duplicate the 2-dimensional molecular structure representing each PRM. Molecular structures should be represented as neutral species (quaternary nitrogen atoms are allowed) with no disconnected fragments (e.g., single structures with no counter ions). The winMolconn program described below can convert any deprotonated functional groups to the neutral form by adding the appropriate number of hydrogen atoms and will discard the counter ion.
For each PRM, the molecular sketching software is used to generate a file which describes the molecular structure of the PRM. The file(s) describing the molecular structures of the PRMs is subsequently submitted to the computer software program winMolconn, version 1.0.1.3 (Hall Associates Consulting, Quincy, Mass., U.S.A., www.molconn.com) , in order to derive various molecular descriptors for each PRM. As such, it is the winMolconn software program which dictates the structure notations and file formats that are acceptable options. These options include either a MACCS SDF formatted file (i.e., a Structure-Data File); or a Simplified Molecular Input Line Entry Specification (i.e., a SMILES string structure line notation) which is commonly used within a simple text file, often with a “.smi” or “.txt” file name extension. The SDF file represents each molecular structure in the format of a multi-line record, while the syntax for a SMILES structure is a single line of text with no white space. A structure name or identifier can be added to the SMILES string by including it on the same line following the SMILES string and separated by a space, e.g.: C1=CC═CC═C1 benzene.
The winMolconn software program is used to generate numerous molecular descriptors for each PRM, which are then output in a table format. Specific molecular descriptors derived by winMolconn are subsequently used as inputs (i.e., as variable terms in mathematical equations) for a variety of computer model test methods in order to calculate values such as: saturation Vapour Pressure (VP); Boiling Point (BP); logarithm of the Octanol/Water Partition Coefficient (log P); Odour Detection Threshold (ODT); Malodour Reduction Value (MORV); and/or Universal Malodour Reduction Value (Universal MORV) for each PRM. The molecular descriptor labels used in the models' test method computations are the same labels reported by the winMolconn program, and their descriptions and definitions can be found listed in the winMolconn documentation. The following is a generic description of how to execute the winMolconn software program and generate the required molecular structure descriptors for each PRM in a composition.

Method for assigning Fragrance Fidelity Index (FFI) and the Blocker Index (BI) for a Malodor Reduction Compound
Blocker materials suitable for use in consumer products of the present invention are chosen for their ability to decrease malodor, while not interfering with perception of a fragrance. Material selection is done by assigning two indices to a test sample material from two reference scales in order to rank odor strengths. The two reference scales are the Fragrance Fidelity Index (FFI) scale and the Blocker Index (BI) scale. The FFI ranks the ability of the test sample material to impart a perceivable odor which could cause interference when combined with another fragrance and the BI ranks the ability of the test sample material to reduce malodor perception. The two methods for assigning the indices to a test sample on the FFI and the BI reference scales are given below.
Method for Assigning the FFI to Test Samples
The first step in the method for assigning an FFI on the FFI reference scale is to create the FFI reference swatches. The swatches for the scale are created by treating clean fabrics swatches with a known amount of a known concentration of an ethyl vanillin solution. Fabric swatches for this test are white knit polycotton (4 inch×4 inch) swatches from EMC ordered as PC 50/50. The supplier is instructed to strip the swatches first, stripping involves washing twice with a fragrance-free detergent and rinsing three times.
Making the FFI Reference Swatches
Make three solutions of ethyl vanillin using a 50%/50% EtOH/water as the diluent at the following concentrations: 25 ppm, 120 ppm and 1000 ppm. Pipette 13 μL of each of the three solutions into the middle of a clean swatch resulting in about a 1 cm diameter of the solution in the middle of the swatch. This will create a sensory scale of three swatches with three different odor levels based on the concentration of the solution pipetted onto the swatch. After drying for 30 minutes in a vented hood, the swatches are wrapped in aluminum foil to prevent odor contamination to the treated swatch. A clean untreated swatch is also included as the lowest anchor point of reference for odor strength on the FFI scale. The FFI reference scale swatches should be used within 0.5 to 12 hours and discarded after 12 hours. The swatches are used as scale anchor points when graders evaluate a test sample(s) and are assigned a Fragrance Fidelity Index (FFI) as show in Table 7.
At least four perfumers/expert graders are used to rank the ethyl vanillin swatches in the FFI scale. The perfumer/expert grader needs to demonstrate adequate discrimination on the scale. The perfumer/expert panel is asked to rank order swatches according to a scale between 0 and 3. The panel must demonstrate statistical differences between the swatches as seen in Table 7.
The expert graders must demonstrate a full range of 2.5 over the 4 swatches to be acceptably discriminating. Grader 2 in table 1 has a range of only 2 and is eliminated from the panel. The panel of expert graders must also demonstrated the ability to statistically discriminate between swatches in the scale.
The reference swatches represent the 0, 1, 2, and 3 FFIs on the FFI reference scale, Table 9. The expert grader should familiarize them self with the strength of the odor on the FFI reference swatches by sniffing each one starting at 0 (the lowest odor strength) and ending at 3 (the highest odor strength). This should be done prior to evaluating the test sample material treated swatch.
Making Swatches Treated with the Test Material
A clean swatch is treated with 13 μL of a known concentration of a test sample material resulting in an about 1 cm of the solution on the clean swatch. Just like the reference swatches, the test sample material swatch is dried in a vented hood for 30 minutes and then wrapped in aluminum foil to prevent contamination. The test material swatches and the FFI reference swatches should be made within 2 hrs. of each other. The test material swatch must be used within 0.5 to 12 hours and discarded after 12 hours.
Assigning the FFI to the Test Material
At least two perfumers/expert graders are used to assign an FFI grade to a test sample. The perfumer/expert grader smells the test sample swatch by holding that swatch 1 inch from their nose with their nose centered over the area where the test sample was pipetted on to the fabric and then assigns the test sample an FFI grade using the FFI reference scale anchor swatches as references. The test sample swatch is assigned an FFI grade at or between numbers on the FFI scale shown in Table 9. In cases where the test sample material is graded greater than 3, the test material is not a blocker material or the concentration of the material needs to be lowered and reevaluated to determine if a lower level has a malodor blocker functionality.
Method for Assigning the BI to Test Sample
The first step in the method for assigning a BI to a test sample material on the BI reference scale is to create the BI reference swatches. The swatches for the scale are created by treating clean fabrics swatches with a known amount of a known volume of isovaleric acid solution at a known concentration. Fabric swatches for this test are white knit polycotton (4 inch×4 inch) swatches from EMC ordered as PC 50/50. The supplier is instructed to strip the swatches first, stripping involves washing twice with a fragrance-free detergent and rinsing three times.
Making the BI Reference Swatches
Make one solution of 0.08% isovaleric acid using 50%/50% EtOH/water as the diluent. The BI scale contains one clean swatch with no malodor applied. Three other swatches each have a different volume of the 0.08% isovaleric acid applied. Pipette 2 μL of the 0.08% isovaleric acid solution to one clean swatch, 5 μL of the 0.08% isovaleric acid solution to the next swatch and 20 μL of isovaleric acid to the final clean swatch. These solutions are pipetted to the middle of the swatches. This will create a sensory scale of three swatches with three different odor levels based on the volume of the 0.08% isovaleric acid solution pipetted onto the swatch. After drying for 30 minutes in a vented hood, the swatches are wrapped in aluminum foil to prevent odor contamination to the treated swatch. A clean untreated swatch is also included as the lowest anchor point of reference for malodor strength on the BI scale. The BI reference scale swatches should be used within 0.5 to 12 hours and discarded after 12 hours. The swatches are used as scale anchor points when graders evaluate a test sample(s) and are assigned a Blocker Index (BI) as show in Table 12.
At least four perfumers/expert graders are used to rank the isovaleric acid swatches in the BI scale. The perfumer/expert grader needs to demonstrate adequate discrimination on the scale. The perfumer/expert grader is asked to rank order swatches according to a scale between 0 and 3. The panel of graders must demonstrate statistical differences between the swatches as seen in Table 10.
The expert graders must demonstrate a full range of 2.5 over the 4 swatches to be acceptably discriminating. The panel of expert graders must also demonstrated the ability to statistically discriminate between swatches in the scale. Expert grader #2 did not demonstrate the ability to discriminate between the swatches and is eliminated from the panel, see Table 11.
The reference swatches represent the 0, 1, 2, and 3 BIs on the BI reference scale, Table 12. The expert grader should familiarizes him/herself with the strength of the odor on the BI reference swatches by sniffing each one starting at 0 (the lowest odor strength) and ending at 3 (the highest odor strength). This should be done prior to evaluating the swatch treated with the test material.
Making the malodorous swatch and treating it with a test material To evaluate the BI, the test material is applied to a malodorous swatch to determine how well the test material blocks the malodor. The malodorous swatch is made by treating a clean swatch with 20 μL of a 0.08% solution of isovaleric acid. Dry the malodorous swatch treated with isovaleric acid in a vented hood for 30 minutes. After drying the malodorous swatch a known concentration of test material solution, between 1 ppm and 100 ppm is pipetted onto the malodorous swatch. Apply the test material solution right on top of the spot where the isovaleric acid solution was applied making an about 1 cm diameter spot. Just like the BI reference swatches, the isovaleric acid+test material swatch is dried in a vented hood for 30 minutes and then wrapped in aluminum foil to prevent contamination. The isovaleric acid+test material swatches and the BI reference swatches should be made within 2 hrs. of each other. The isovaleric acid+test material swatch must be used between 1-12 hours just like the reference swatches. It is sometimes necessary to evaluate several levels of the test material between about 1 and about 100 ppm to determine the BI.
Assigning the BI to the Test Material
At least two perfumers/expert graders are used to assign the BI to the test sample. The expert grader smells the isovaleric acid+test material swatch by holding that swatch one inch from their nose with their nose centered over the area where the Test sample was pipetted on to the fabric and then assigns the isovaleric acid+test material swatch a BI based on ranking its odor strength against the odor strength of the swatches in the BI reference scale. The test sample swatch is assigned a BI at or between numbers on the BI in table. In cases where the isovaleric acid+test material swatch odor is greater than 3 on the BI reference scale, this indicates the material is not a blocker or the concentration of the test material needs to be lowered to achieve its blocker functionality.

Below are some non-limiting examples of preferred behavior by which the malodor control compound gives improved malodor control at lower concentration. These nonlimiting data provide additional compelling data that malodor is being blocked, not masked.
Retesting Malodor Reduction Compounds at Lower Levels.
The example below demonstrates that while a malodor control compound could fail to demonstrate odor blocking (BI>2.5) at a higher concentration it should be retested at a lower concentration to determine if it passes.
In the present invention blends enable more potent malodor reduction because blends are useful at a higher % of the product composition before becoming olfactively noticeable. Below are non-limiting examples of malodor reduction compounds.
Each of the malodor reduction compositions of Examples 1 through 3 are used as a perfume component in an Article at a level of form about 0.00001 mg to about 50 mg by combining the malodor reduction composition at a level of about 0.01% to about 30% based on total perfume composition weight. Addition Examples are as follows:
The malodor reduction compositions of Examples 1, 2 and 3 are used separately as a perfume component on three separate pads. 1 mg of each perfume component is added onto the top surface of an Always Ultra Thin Unscented menstrual pad. Optionally, if a scented pad is desired, 1 mg of a second fragrance (perfume 2) can be added to each pad. This second fragrance is preferably added beneath the core of the pad.
The malodor reduction compositions of Examples 1, 2 and 3 are used separately as a perfume component on three separate Heavy AI Pants. 2 mg of each perfume component is added onto the top surface of an Always Discreet Adult Incontinence Underwear, moderate absorbency. Optionally, if a scented article is desired, 2 mg of a second fragrance (perfume 2) that is different can be added. This second fragrance is preferably added beneath the core of the article.
The malodor reduction compositions of Examples 1, 2 and 3 are used separately as a perfume component on three separate Pampers Cruisers Baby Diapers. 4 mg of this solution is added onto the top of the Pampers Cruisers Baby Diaper. Optionally, if a scented diaper is desired, 1 mg of a second fragrance (perfume 2) that is different can be added. This second fragrance is preferably added beneath the core of the diaper.
The dimensions and values disclosed herein are not to be understood as being strictly limited to the exact numerical values recited. Instead, unless otherwise specified, each such dimension is intended to mean both the recited value and a functionally equivalent range surrounding that value. For example, a dimension disclosed as “40 mm” is intended to mean “about 40 mm.”
Every document cited herein, including any cross referenced or related patent or application is hereby incorporated herein by reference in its entirety unless expressly excluded or otherwise limited. The citation of any document is not an admission that it is prior art with respect to any invention disclosed or claimed herein or that it alone, or in any combination with any other reference or references, teaches, suggests, or discloses any such invention. Further, to the extent that any meaning or definition of a term in this document conflicts with any meaning or definition of the same term in a document incorporated by reference, the meaning or definition assigned to that term in this document shall govern.
While particular embodiments of the present invention have been illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the invention. It is, therefore, intended to cover in the appended claims all such changes and modifications that are within the scope of this invention.
