Definitions

  • the present invention is generally directed to the control of odors resulting from the decomposition of human efflux, and in particular, the effect of a hydroxydiphenyl ether in a modified acidic environment applied to a personal hygiene product to control odors resulting from autolytic and enzymatic decomposition of human exudates and excreta into volatile nitrogenous byproducts.
  • Disposable absorbent personal hygiene products are designed to capture and retain human excreta in a convenient and in-expensive article. Advances in performance have been made in disposable diapers, adult incontinence pads and feminine hygiene products to further improve waste acquisition and maintain skin wellness. Enhanced top-sheet layers have been introduced that reduce the contact abrasion due to friction of the personal hygiene against one's skin. Transfer intermediate layers are constantly in development whereby the waste, and in particular urine, is quickly wicked from the top-sheet to an absorbent core material. Improved core materials are available that can retain a liquid insult in spite of external compressive forces. While such advances have improved physical performance with regard to liquid and solid wastes, the decomposition of those wastes into volatile byproducts has been addressed with only limited effectiveness.
  • Disposable diapers and adult incontinence pads have improved in retention capability and can be worn for longer periods without loss of waste containment. While issues related to containment have improved, the development of odors remains a problem.
  • Urine a primary form of liquid waste encountered by diapers and incontinence pads, is comprised in significant part of urea.
  • the decomposition of urea results in the formation of volatile nitrogenous byproducts, most notably being ammonia, which are particularly malodorous.
  • ammonia odor may be controlled is to target the degradation pathways, which produce ammonia.
  • Enzymatic decomposition is an active process induced by specialized enzymes found in bacterial flora. Many genera of bacteria are ubiquitous to the human skin, the gastrointestinal tract, and the uro-genital tract as well as in the form of environmental contaminates found in the personal hygiene products itself. A general category of enzyme present in this flora allows for the breakdown of urea into ammonia. This enzyme is referred in general as a catalase, and specifically as a urease. When there is a liquid insult onto the hygiene product, bacteria are carried along with the liquid front and into the interstices of the fibrous construction. Ureases in the bacterial burden are active during this period, adding significantly to the production of ammonia. Certain bacteria are particularly receptive to this environment and will thrive, blooming the bacterial count and further increasing urea decomposition over time.
  • the present invention is directed to the control of noisome odors created by the decomposition of human waste in a personal hygiene product.
  • Control of the decomposition process is by the pre-application of an odor control compound comprising a hydroxydiphenyl ether in a modified acidic environment to one or more components of the personal hygiene product.
  • the odor control compound exhibits a multi-functional performance, affecting not only the odiferous decomposition byproducts, but also the biochemical decomposition and degradation pathways.
  • FIG. 1 and FIG. 2 shows typical hygiene product constructions, whereby the urine contacts 10 or 14 a proximal surface of the hygiene product, then wicks through that surface and one or more other dispersing layers, eventually being absorbed into the structure of a 12 lofty fibrous core.
  • Urea a compound comprising a significant amount of the urine chemistry, decomposes by autolytic and enzymatic mechanisms.
  • the urea is broken down into nitrogenous volatile byproducts, most notably being ammonia. As ammonia evolves out of the solid hygiene product, both malodorous and detrimental skin-wellness effects occur.
  • the production of ammonia is significantly curtailed.
  • the hydroxydiphenyl ether reduces the metabolic performance of bacteria present in the environment.
  • the presence of the hydroxydiphenyl ether in a modified acidic carrier further improves the bacteriostatic performance of the ether as well as introducing a pH shift that disfavors the further release of ammonia by inducing protonation of the ammonia into a nonvolatile ammonium ion.
  • the hydroxydiphenyl ether can be present in conjunction with the modified acidic carrier or located within immediate proximity.
  • a preferred embodiment involves the admixing of the hydroxydiphenyl ether with the modified acidic carrier in an aqueous solution. This aqueous solution can then be applied to one or more layers of the personal hygiene product prior to or during product fabrication.
  • the hydroxydiphenyl ether can be incorporated into the polymeric composition prior to the formation of that composition into a construct, such as a fiber, filament or film, with the modified acidic carrier being applied topically thereafter. As the hydroxydiphenyl ether blooms to the surface of the construct, interaction with the modified acidic carrier can readily occur.
  • FIG. 1 is a cross-sectional diagram of a typical personal hygiene product
  • FIG. 2 is a cross-sectional diagram of a modified personal hygiene product having a unified top sheet and transfer layer.
  • R′, R′′, and R′′′ are selected halogen substitutions.
  • a preferred hydroxydiphenyl ether is a trichloro- derivative as described and synthesized in U.S. Pat. Nos. 3,506,720 and 3,629,477, hereby incorporated by reference.
  • the trichlorodiphenyl ether exhibits bacteriostatic properties in the presence of the bacterial flora found in the personal hygiene product. It is postulated that the reduction of bacterial load reduces the number of viable and metabolically active bacteria, which results in a corresponding decrease in the concentration of catalases found in those bacteria.
  • a reduction in catalase activity primarily ureases, subsequently reduces the rate at which urea is decomposed into ammonia, and thereby reducing the noisome odors formed in the hygiene product.
  • modified acidic carriers include those acids that shift the pH of the trichlorodiphenyl ether environment to an approximate range of between 3.0 and 5.0. It is within the purview of the present invention that either inorganic or organic acids, alone or in combination, can be used in the capacity of a modified acidic carrier.
  • a presently preferred modified acid carrier is one selected from the aliphatic acids, with hexanedioic acid being most preferred.
  • the hydroxydiphenyl ether and modified acid carrier can be incorporated into a personal hygiene product, such as a sanitary napkin, diaper, training pant, incontinence pant, and the like, by a number of different routes, including as a topical treatment, a spin finish, and/or a melt additive.
  • Topical treatment is particularly efficacious in incorporating the odor control compound as a simple aqueous solution can be prepared and applied directly to a substrate material, which is then used as one or more component layers in the fabrication of a personal hygiene product.
  • Suitable substrate materials include nonwoven fabrics, woven fabrics, and films.
  • a 50 gram per square meter nonwoven fabric was fabricated from carded and thermally bonded staple fiber batt.
  • the staple fiber used was a Type T-187 blue pigmented polypropylene polymer with a 1.5′′ staple length and a diameter of 12 dpf, as supplied by Fibervisions of Athens, Ga.
  • the staple fiber was carded by conventional practice known to those skilled in the art and subsequently thermal bonded by use of a heated calender.
  • a calender temperature of about 340° F. and a nip pressure of 470 pounds per linear inch were employed.
  • Example 1 The nonwoven fabric of Example 1 was subsequently treated with an odor control compound comprising 3 mM trichlorodiphenyl ether, supplied as “MICROBAN” from the Microban Corporation, 68 mM hexanedioic acid, and deionized water.
  • a Weko Atomizer was used to uniformly distribute the odor control compound to the nonwoven fabric at an add-on level of 15% by weight.
  • Table 1 presents the effect of untreated and treated nonwoven fabric on bacterial growth.
  • Example 1 and Example 2 were placed on uniform bacterial lawns, then incubated overnight. Individually tested bacterial organisms where unable to live under the conditions imposed by the treated nonwoven material whereas the untreated material had no effect.
  • Table 2 is a variation of the zone of inhibition test performance given in Table 1. A test was performed whereby a bacterial broth receives a one inch sample of either Example 1 or Example 2, then allowed to incubate overnight. When compared to control bacterial broth of known viable organism count, the untreated material is seen to have no significant deleterious effect where as the odor control treated material has reduced viable cell count by at least 95 %.
  • Table 3 provides results on the effectiveness of the odor control compound on perceived odor production.
  • Ten inch by seven inch samples were taken from Example 1 and Example 2. These samples were then substituted for the transfer layer of a “SERENITY” brand adult incontinence pant, a registered trademark of Johnson & Johnson, and a five inch square sample of the entire construct excised from the central medial region of the pant. The construct samples were then transferred to the interior bottom surface of individual glass container. A 100 ml volume of mock urine seeded with bacteria was then applied to the samples and the glass containers closed. At time points throughout the testing period, the container was briefly opened and the odor compared against the control. As can be seen from the data provided, the perceived smell was significantly reduced.
  • the present invention is applicable to disposable absorbent articles such as incontinence briefs, incontinence undergarments, diapers, training pants, pull-on garments, feminine hygiene garments, sanitary napkins, and the like.
  • a diaper for example, preferably comprises a containment assembly comprising an odor control liquid pervious topsheet; a liquid impervious odor control backsheet joined to the odor control topsheet; and an odor control absorbent core positioned between the odor control topsheet and the odor control backsheet.
  • the odor control absorbent core has a pair of opposing longitudinal edges, an odor control inner surface and outer surface.
  • the diaper can further comprise elastic leg features, elastic waist features, and a landing member.
