Patent Application

The present invention relates to malodor reduction compositions and methods of making and using same.
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. Manufacturers often 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, 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.
The present invention relates to malodor reduction compositions and methods of making and using same. The malodor reduction compositions are suitable for use in a variety of applications, including use in consumer products, for example, air freshening compositions, laundry detergents, fabric enhancers, surface cleaners, beauty care products, dish care products, diapers, feminine protection articles, and plastic films for garbage bags. Such malodor control technologies do not unduly interfere with the scent of the perfumed or unperfumed situs 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.
As used herein “consumer product” means baby care, beauty care, fabric & home care, family care, feminine care, health careproducts or devices. Such products include but are not limited to plastic films garbage bags, storage bags, storage wraps, diapers, bibs, wipes, garments, textiles including sheets and towels, composters; products for and/or methods relating to treating hair (human, dog, and/or cat), including, bleaching, coloring, dyeing, conditioning, wet or dry shampooing, styling, scalp treatments; deodorants and antiperspirants; personal cleansing; cosmetics; skin care including application of creams, lotions, fine fragrances and other topically applied products for consumer use; and shaving products, products for and/or methods relating to treating fabrics, hard surfaces and any other surfaces in the area of fabric and home care, including: air care including air filtration, car care, dishwashing, fabric conditioning (including softening), laundry detergency, laundry and rinse additive and/or care, hard surface cleaning and/or treatment, towel bowl cleaners and other cleaning and/or malodor treatments for consumer, agricultural, industrial or institutional use; products and/or methods relating to bath tissue, facial tissue, paper handkerchiefs, and/or paper towels; tampons, feminine napkins; products and/or methods relating to oral care including toothpastes, tooth gels, tooth rinses, denture adhesives, tooth whitening.
As used herein “energized system”, refers to a system that operates by using an electrical and/or mechanical energy source such as a battery or electrical wall outlet to emit the malodor reduction composition. Examples of such devices include but are limited to liquid electric pluggable type air freshening devices.
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, “neutralize” or “neutralization” refers to the ability of a compound or product to reduce or eliminate malodorous compounds. Odor neutralization may be partial, affecting only some of the malodorous compounds in each context, or affecting only part of a malodorous compound. A malodorous compound may be neutralized by chemical reaction resulting in a new chemical entity, by sequestration, by chelation, by association, or by any other interaction rendering the malodorous compound less malodorous or non-malodorous.
As used herein, “non-energized” refers to a system that emits a targeted active passively or without the need for an electrical energy source. Handheld aerosol sprayers and traditional trigger/pump sprayers are considered non-energized systems.
As used herein, “odor blocking” refers to the ability of a compound to dull the human sense of smell.
As used herein, “odor masking” refers to the ability of a compound with a non-offensive or pleasant smell that is dosed such that it limits the ability to sense a malodorous compound. Odor-masking may involve the selection of compounds which coordinate with an anticipated malodor to change the perception of the overall scent provided by the combination of odorous compounds.
As used herein, “compostable film” means a film that, when made into a bag, meets the testing specifications found in ASTM D6400.
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.
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.

The level of quaternary ammonium ester softening active may depend of the desired concentration of total softening active in the composition (diluted or concentrated composition) and of the presence or not of other softening active. While higher FSA levels improve the softness benefits, the risk on instabilities is typically higher in fabric softener compositions with higher FSA levels.

Examples 111 to 11.4 are made by combining the molten fabric softener active with the front-end stability agent to form a first mixture. This first mixture is combined with water and hydrochloric acid using a high shear mixing device to form a second mixture. The adjunct ingredients are combined with the second mixture using low shear mixing to form the fabric enhancing formula.
