DETAILED DESCRIPTION OF THE INVENTION DEFINITIONS “Renewable resource” is used herein to refer to a resource that is produced by a natural process at a rate comparable to its rate of consumption. The resource can be replenished naturally or by engineered agricultural techniques. Examples of renewable resources include but are not limited to plants (e.g., sugar cane, beets, corn, potatoes, citrus fruit (e.g. oranges), woody plants, cellulosic waste, etc.), animals, fish, bacteria, fungi, and forestry products (e.g. pine and spruce trees). These resources can be naturally occurring, hybrids, or genetically engineered organisms. Natural resources such as crude oil, coal and natural gas are not considered renewable as they are derived from materials that will run out or will not be replenished for thousands or even millions of years. “Bio-based” is used herein to refer to a component of the hot melt adhesive composition that is at least partially produced or is partially derived from a renewable resource. “Environmentally conscious” is used herein to refer to a component of the hot melt adhesive composition that has at least one property selected from the group consisting of bio- based and having a total cradle to gate CO 2 emission value of less than 1.5 kgCO 2 e/kg as evaluated by ISO-14040/14044.

The hot melt adhesive composition can be free of petroleum derived tackifying agents. The hot melt adhesive composition can be free of petroleum derived tackifying agents and petroleum derived plasticizers. The hot melt adhesive compositions of this invention include a high weight percent of environmentally conscious components. The environmentally conscious components can be bio-based. The bio-based components are produced or derived from renewable resources. The bio-based components can be produced or derived from at least 25% by weight, at least 50% by weight, at least 75% by weight, at least 85% by weight, at least 90% by weight, at least 95% by weight, from 60% by weight to 85% by weight, from 60% by weight to 95% by weight, from 60% by weight to 100% by weight, from 65% by weight to 100% by weight, from 75% by weight to 100% by weight, from 80% by weight to 100% by weight or even 100% by weight (i.e. entirely) from renewable resources. The bio-based components can have bio-based carbon content according to ASTM 6866-20 of at least 25%, at least 30%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, from 25% to 100%, from 50% to 100%, from 70% to 100%, from 90% to 100%, or even 100% based on the total carbon content. The hot melt adhesive composition can include at least 45% by weight, at least 50% by weight, at least 55% by weight, at least 60% by weight, at least 65% by weight, at least 70% by weight, at least 75%, at least 80% by weight, from 50% by weight to 95% by weight, from 50% by weight to 100% by weight, from 55% by weight to 100% by weight, from 60% by weight to 100% by weight, from 65% by weight to 100% by weight, from 70% by weight to 100% by weight, from 75% by weight to 100% by weight, from 80% by weight to 100% by weight, or even 100% by weight of components selected from the group consisting of having a total CO 2 emission of less than 1.5 kgCO 2 and bio-based . Environmentally conscious components can have a total CO 2 emission of less than 1.5 kgC0 2 , less than 1.0 kg CO 2 e/kg, less than 0.5 kg CO 2 e/kg, or even less than 0 kgCO 2 e/kg. The hot melt adhesive compositions of this invention can have a Brookfield Viscosity at 149°C of less than 15,000 cP, less than 10,000 cP, from 500 cP to 20,000 cP, or even from 500 cP to 15,000 cP. The hot melt adhesive compositions of this invention utilize an environmentally conscious aliphatic plasticizer having a cycloaliphatic content of no greater than 2%, as tested by 1 H-NMR Spectroscopy. The inventors have discovered that as compared to prior art environmentally conscious plasticizers (that are primarily polar), this unique environmentally conscious aliphatic plasticizer can increase the bio-based content of the composition while still providing performance over a broad temperature range as indicated as by an increased Temperature Plateau Range as compared to compositions including prior art bio-based plasticizers (e.g., Control 1 versus Ex 1). The Temperature Plateau Range is a predictor of the temperature range through which the hot melt adhesive composition has consistent cohesive strength. Further, an upper Temperature Plateau limit of greater than 60°C is helpful to prevent cold flow during storage and shipping. THERMOPLASTIC POLYMER The hot melt composition includes a thermoplastic polymer. The thermoplastic polymer can comprise one or more thermoplastic polymers. The thermoplastic polymer can be environmentally conscious, or even bio-based. Bio- produced monomers can be used to make the bio-based thermoplastic polymer. It is anticipated that thermoplastic polymers made with bio-produced monomers will have similar properties to those made with petroleum derived monomers. The bio-produced monomers can be selected from the group consisting of ethylene, propylene, isoprene, butadiene, styrene, etc. However, useful bio-produced monomers are not restricted to this group. Bio-produced monomers are commonly derived from cellulose, starch and sugar e.g. glucose. Alternatively, the thermoplastic polymer can be considered sustainable even when the bio-based origin cannot be detected by the radiocarbon method (ASTM 6866-20) due to time or dilution effects, but rather sustainability is demonstrated by relevant mass-balance methods (e.g. International Sustainability & Carbon Certification (ISCC) PLUS mass balance approach). Alternatively, the thermoplastic polymer can be derived from petroleum-based materials. Environmentally conscious, bio-based, polymers considered sustainable by the mass balance approach and petroleum-based thermoplastic polymers can be combined in the present invention in any ratio, depending on cost and availability. Recycled thermoplastic polymers can also be used, alone or in combination with bio-based, sustainable polymers by mass balance approach and/or petroleum-based thermoplastic polymers. The thermoplastic polymer can be selected from the group consisting of olefin polymer, styrene block copolymer, functionalized versions thereof (e.g., hydroxyl modified or maleic anhydride modified), and combinations thereof. The olefin polymer can be selected from the group consisting of ethylene-based polymers (e.g., ethylene homopolymers and ethylene copolymers), propylene-based polymers (e.g., propylene homopolymers and propylene copolymers), functionalized versions thereof (e.g., hydroxyl modified or maleic anhydride modified), and combinations thereof. The thermoplastic polymer can be prepared using a variety of catalysts including, e.g., a single site catalyst (e.g., metallocene catalysts (e.g., metallocene catalyzed ethylene alpha- olefin copolymers), constrained geometry catalysts (e.g., homogeneous linear or substantially linear ethylene alpha-olefin interpolymers prepared from ethylene and an alpha-olefin comonomer using a constrained geometry catalyst and having a polydispersity index of no greater than 2.5 and possessing long chain branching)), multiple single site catalysts, Ziegler- Natta catalysts and combinations thereof. The thermoplastic polymer can include functional groups (i.e. be functionalized) including, e.g., carboxylic acid groups, anhydride groups (e.g., maleic anhydride), and combinations thereof. If the hot melt adhesive composition includes a functionalized thermoplastic polymer, it can also include a second thermoplastic polymer that is not functionalized. The hot melt adhesive composition can include from 3% by weight to 25% by weight, from 5% by weight to 25% by weight, or even from 5% by weight to 15% by weight of the functionalized thermoplastic polymer. The hot melt adhesive composition can further include from 3% by weight to 25% by weight, from 5% by weight to 25% by weight, or even from 5% by weight to 15% by weight of the second thermoplastic polymer that is not functionalized. If petroleum-based polymer is used, the amount of thermoplastic polymer can be limited to maximize the bio-based material content. The hot melt adhesive composition can include from 3% by weight to 60% by weight, from 5% by weight to 60% by weight, from 10% by weight to 50% by weight, from 10 % by weight to 40% by weight, from 10% by weight to 30% by weight, from 3% by weight to 25% by weight, from 10% by weight to 25% by weight, or even from 12% by weight to 20% by weight of thermoplastic polymer.

The polymer can be an ethylene-based polymer having a density of no greater than 0.90 grams per cubic centimeter (g/cm3), or even no greater than 0.88 g/cm3. The ethylene- based polymer can be an ethylene alpha-olefin copolymer.

The styrene block copolymer can include more than one styrene block copolymer. When more than one styrene block copolymer is included the styrene content, the diblock content and the melt flow rate ranges specified below are a weight average of all the grades present. As an example, if the hot melt adhesive composition comprises two styrene block copolymers A and B. Polymer A is present at 25 weight % (wA) with a styrene content of 15% (sA) and polymer B is present at 25 weight % (wB) with a styrene content of 20 weight % (sB). The average styrene content of the styrene block copolymer is calculated in the following way: wA/( wA+wB)* sA + wB/( wA+wB)* sB = 0.5 (15) + 0.5 (20) = 17.5 weight %.

USES The hot melt adhesive compositions of this invention can be used in many different applications and for a variety of end uses including pressure sensitive adhesives (e.g. removable and permanent types), bookbinding adhesives, adhesives to attach inserts to published materials (e.g. magazines), adhesives to assemble various items (e.g. filters), adhesives for packaging constructions (e.g. cases, cartons, trays, etc.), adhesives for tapes and labels, and adhesives for disposable articles. TAPES AND LABELS The hot melt adhesive compositions of this invention can be used to make adhesive tapes or alternately to adhere labels to various items (e.g. containers, magazines, etc.). The label/tape can be selected from a variety of materials including paper, non-paper films (e.g. polypropylene (e.g. polypropylene (PP), oriented polypropylene (OP), and biaxially oriented polypropylene (BOPP)), polyethylene, etc.). The container can be metal (e.g. aluminum or steel) or plastic (polyethylene terephthalate (PET), high density polyethylene (HDPE) and polypropylene. The label can be a spot label i.e. a label that does not extend completely around the container. Alternatively, the label can be a wraparound label i.e. a label that completely wraps around the entire container. If the label is a wraparound label, it can be roll fed into the applicator. Alternatively, the labels are pre-cut and fed in from a stack. In a wraparound label application method, the label stock is fed into a label station. A pick-up adhesive and a lap glue are then applied to the label, often from the same glue pot. A pick-up adhesive adheres the leading edge of the label to a container. The lap glue then bonds the overlap where the wrap around label overlaps itself. The hot melt adhesive composition of this invention can be both the pick-up adhesive and the lap glue. DISPOSABLE ABSORBENT ARTICLES The hot melt adhesive composition can be applied to (i.e. such that it is in direct contact with) or incorporated in a variety of substrates including, e.g., films (e.g., polyolefin (e.g., polyethylene and polypropylene), bio-based films), release liners, porous substrates, cellulose substrates, sheets (e.g., paper, and fiber sheets), paper products, woven and nonwoven webs, fibers (e.g., synthetic polymer fibers and cellulose fibers) and tape backings. The hot melt adhesive composition is also useful in a variety of applications and constructions including, e.g., disposable absorbent articles including, e.g., disposable diapers, adult incontinence products, sanitary napkins, medical dressings (e.g., wound care products) bandages, surgical pads, pet training pads (e.g. puppy pads) and meat-packing products and components of absorbent articles including, e.g., an absorbent element, absorbent cores, impermeable layers (e.g., backsheets), tissue (e.g., wrapping tissue), acquisition layers and woven and nonwoven web layers (e.g., top sheets, absorbent tissue) and elastics. The hot melt adhesive composition is useful on substrates made from a variety of fibers including, e.g., natural cellulose fibers (e.g. wood pulp, cotton, viscose, starch, etc.), silk, PLA(poly lactic acid), PHA(poly hydroxyl alkanoates), PBS(poly butylene succinate), PBAT (poly butylene adipate terephthalate) and wool; synthetic fibers such as nylon, rayon, polyesters, acrylics, polypropylenes, polyethylene, polyvinyl chloride, polyurethane, and glass; recycled fibers, and various combinations thereof. The hot melt adhesive composition is useful on a variety of films including polyethylene, polypropylene, ethylene vinyl acetate, ethylene copolymer, bio-based films (e.g. PLA, PHA, starch, etc.). Various application techniques can be used to apply the composition to a substrate including, e.g., slot coating, spraying including, e.g., spiral spraying and random spraying, screen printing, foaming, engraved roller, extrusion and melt blown application techniques. METHODS OF MAKING DISPOSABLE ABSORBENT ARTICLES The hot melt adhesive compositions of this invention can be used in a wide variety of applications within the disposable absorbent article. The hot melt adhesive compositions can be used as construction adhesives (e.g. used to bond the back sheet to the nonwoven and optionally the absorbent pad), as a positioning adhesives (e.g. to adhere a disposable absorbent article to an undergarment), as an elastic attachment adhesive (e.g. bonding the elastic material to the back sheet in for example the leg or waist area), or to attach elastic material to any other portion of the article, and for core stabilization (e.g. applying a hot melt composition to the absorbent core to increase the strength of the core). The hot melt adhesive composition can be used for construction applications. In a typical construction application in the manufacture of a disposable absorbent article, a body fluid impermeable back sheet is bonded to a nonwoven substrate. The hot melt adhesive composition may also be used to bond at least one additional layer or material selected from the group consisting of absorbents, tissues, elastomeric materials, superabsorbent polymers, and combinations thereof. For example, the adhesive can further be used for back sheet lamination i.e. where the body fluid impermeable backsheet typically a film (e.g. polyethylene, polypropylene, ethylene vinyl acetate, ethylene copolymer, bio-based etc.) is bonded to a second nonwoven to improve the feel of the disposable article. The hot melt adhesive composition can be used as a positioning adhesive. A positioning adhesive is disposed on at least one substrate surface of a disposable absorbent article and can be used to position an absorbent article on a garment such as underwear. Such disposable absorbent articles include, e.g., feminine hygiene articles such as sanitary napkins and panty liners, diapers, disposable garments having a waist opening and leg openings, and adult incontinence articles. In one construction, the absorbent article (e.g., a feminine hygiene article) includes a garment facing surface and a body facing surface, a topsheet having a garment facing surface and a body facing surface, a backsheet having a garment facing surface and a body facing surface, and an absorbent core disposed between the body facing surface of the backsheet and the garment facing surface of the topsheet. The pressure- sensitive adhesive composition is disposed on the garment facing surface of the adsorbent article, in general, or even on the garment facing surface of the backsheet. A release liner optionally is disposed on the pressure-sensitive hot melt adhesive composition to protect the pressure-sensitive adhesive composition until use. The absorbent article (e.g., a feminine hygiene article) optionally includes additional layers and adhesives and the components of the absorbent article optionally exhibit additional functionality. Examples of additional layers, functionality and combinations thereof include dusting, wicking, acquisition, additional top sheets, multiple core layers, superabsorbent particles and compositions, wetness indicators, and combinations thereof. The invention will now be described by way of the following examples. All parts, ratios, percents and amounts stated in the Examples are by weight unless otherwise specified. EXAMPLES Test procedures used in the examples and throughout the specification, unless stated otherwise, include the following. Brookfield Viscosity Test Method Viscosity was determined in accordance with ASTM D-3236 entitled, “Standard Test Method for Apparent viscosity of Adhesives and Coating Materials,” (October 31, 1988), using a Brookfield Thermosel viscometer Model DV12 and a number 27 spindle. The results were reported in centipoise (cP). Glass Transition Temperature (Tg) Test Method The glass transition temperature (Tg) of the samples was determined using Dynamic Mechanical Analysis (DMA) with a DHR-II instrument using the following conditions: the sample was heated to 150°C, held at 150°C for 5 minute, cooled to -20°C at 3°C/minute and 10 rad/second, with 10% strain. The Tg was the temperature at which the tan delta curve exhibits a local maxima at material transition zone between the glassy and rubbery regions, usually between -20°C and 40°C. Temperature Plateau Range The temperature plateau range was obtained using Dynamic Mechanical Analysis (DMA) with a DHR-II instrument using the following conditions: the sample was heated to 150°C, held at 150°C for 5 minute, cooled to -20°C at 3°C/minute and 10 rad/second, with 10% strain. As temperature decreases from 150°C, storage modulus G’ and loss modulus G” increase. The temperature, at which both these two curves cross over, was called first crossover-temperature (T1). This was where material transitions from melt to rubbery plateau region. As temperature continues to decrease, G’ and G” curves cross over again, when material starts to transition into glassy state. This temperature was called second crossover- temperature (T2). T1 and T2 define the temperature plateau range. Cycloaliphatic Content Cycloaliphatic content was obtained using H-1 Nuclear Magnetic Resonance (1H- NMR) Spectroscopy. The summation of the signals from 1.9-2.5 ppm was calculated as a percentage from the total aliphatic hydrogen summation from 0.2-3.7 ppm. If antioxidant or other additives were present in the oil sample, the respective resonances for these additives were omitted from the integration regions defined. Molten Gardner Color The adhesive is tested (in the molten state) to determine Gardner color by comparing the color of the sample against the Gardner Color Standards as set forth in ASTM D-1544. The comparison is made using a Gardner Delta Comparator equipped with an Illuminator available from Pacific Scientific (Bethesda, Maryland). Dynamic Peel Test Sample Preparation Method A slot coating applicator, which was 1 inch (25.4 mm) wide, and a laminator were set to an application temperature of 149°C., a nip pressure of 103.4 kilopascal (15 psi), and minimal rewind and unwind tensions so as not to stretch the film. The hot melt adhesive composition was applied continuously at a coat weight of 3 g/ m2 on an embossed non- breathable, layered polyethylene film having a thickness of 0.9 mil (0.023 mm), and laminated with an oriented polypropylene nonwoven web having a thickness of 4 mil (0.1 mm) and a basis weight of 0.45 ounces per square yard (15.3 g/m2) at a speed of around 184m/min. Dynamic Peel Test Method Dynamic Peel was determined according to ASTM D1876-01 entitled, "Test Method for Determining Peel Resistance of Adhesive (T-Peel Test Method)," with the exception that the test was run at 30.5 centimeters per minute (12 in/min) over a period of 10 seconds and 6 replicates were run. The samples were run on an IMASS Spec-type test instrument. The samples were peeled along the machine coating direction. The average peel value over 10 seconds of peeling was recorded, and the results were reported in grams. The initial Dynamic Peel value was the value measured 24 hours after the sample was prepared. Six replicates were tested and the average value was reported in units of grams of force per 25mm (gf/25mm). Sample Preparation Method for Cotton Peel Force Test A laminate was prepared by coating a sample composition onto a silicone coated release paper in a one inch wide pattern at an add-on weight of 20 grams per square meter (g/m2) (+/- 3 g/m2) using a slot applicator and then contacting the adhesive strip with the treated side of a 0.9 mil (0.023 mm) thick polyethylene film to form a silicone coated release paper/adhesive/polyethylene film laminate. Test samples having a length of 4 inches (in) (10.16 cm) in the machine coating direction and 2 in (5.08 cm) in the cross-machine direction were then cut from the laminate such that the adhesive pattern was centered in the cross- machine direction of the test sample.

Cotton Peel Force Test Method For cotton bonds a sheet of 124 g/m2 bleached t-shirt cotton fabric (Testfabrics, Inc., West Pittston, Pennsylvania) was cut into strips having a length of 4 in (10.16 cm) in the machine direction and a width of 1.5 in (3.81 cm) in the cross-machine, before cutting the cotton fabric, the grid work of the stitching of the fabric was examined. When the cotton fabric was stretched, the sample will exhibit greater elongation in one direction than in another direction. The cotton fabric was cut lengthwise in the direction that has less elongation. All cotton fabric strips were cut as straight as possible along the stitching grid work. If the cotton fabric strips were cut askew, an inconsistent elongation of the cotton fabric test sample will result. The release film was removed from the adhesive and the adhesive side of each test sample was gently placed on the surface of a cotton strip such that the cotton curls away from the adhesive bond to form the composite test sample, taking care not to press the adhesive down on to the test fabric. That was, the easier to bond to side of the cotton fabrics was used in peel testing. The resulting test specimen was then placed on a mechanical roll-down device equipped with a 4.5-pound roller, and the roller was allowed to pass two times over the sample, i.e., one forward pass and one backward pass, at a rate of approximately 12 in/min (305mm/min) once in each lengthwise direction, ensuring that the sample is free of entrapped air bubbles. A timer was then activated, and the sample was placed into the jaws of INSTRON- type peel tester. The polyethylene film was placed into the moving jaw, and the fabric was attached to the stationary jaw. Within one minute after the sample has been removed from the roll-down device, the sample was tested according to ASTM D1876-01 entitled, “Test Method for Determining Peel Resistance of Adhesive (T-Peel Test Method),” with the exception that the test is run at a rate of 305 mm/min, instead of 250 mm/min, over a period of ten seconds, and at least five replicates were run instead of the ten specified in ASTM D1876. The average peel force over ten seconds of peeling was recorded, and the results were reported in grams. The initial peel force was measured 24 hours after the test sample was prepared. The following grades of styrene block copolymer are used in the Examples. JH8151 - SIS, 16% by weight styrene, MFR = 10 (200°C, 5 kg) KIBITON PB 5502 – SBS, 36.5% by weight styrene, MFR = 8 (190°C, 2.16 kg) VECTOR 4211- SIS, 30% by weight styrene, MFR = 13 (200°C, 2.16 kg) GLOBALPRENE 3546 – SBS, 40% styrene, MFR = 6 (200°C, 2,16 kg) STYROFLEX 2G66 – S-TPE-S, 64% styrene, MFR=11 (200°C, 5 kg)
