Definitions

  • the present invention relates to fabric softening dryer sheets that can neutralize odors on fabric while the fabric is being worn as well as removing existing odors on such fabrics while being laundered.
  • malodors i.e., undesirable odors
  • a deodorizing method a masking process, an absorption process, an ozone deodorizing process, or a catalytic process, which uses a catalytic material such as a metal oxide or enzyme.
  • Masking processes control malodors by vaporizing and dispersing an aromatic liquid or solid such as a perfume into the ambient that contains the malodor. Thus, masking processes modify the malodor to a more pleasant character by superimposing a dominant, but more pleasant odorant into the ambient.
  • One problem with conventional aromatic liquids and solids is that such compounds tend to evaporate over an extended period of time which may result in the return of the malodor.
  • Absorption processes control malodors by employing an absorbent such as activated carbon or the like which absorbs odor components from the ambient.
  • the level of intensity of the malodor is constantly being reduced from the ambient and thereby refreshing the ambient.
  • the ozone deodorizing process serves to decompose odor components with ozone, and in catalytic processes the odor components are modified in some fashion by the catalyst being used.
  • catalytic processes enzymes are employed as the deodorizers.
  • malodor control and/or elimination is achieved mainly by using either a masking process or an absorption process since ozone and catalytic processes are generally not feasible.
  • Some commonly employed odor absorbents in home care applications are formulations that are based on bleach oxidizing agents, peroxides, bactericides - which kill microorganisms, cyclodextrins, and/or zinc ricinoleate. Such compounds tend to form strong bonds with malodor molecules containing sulfur and nitrogen atoms.
  • compositions such as zinc ricinoleate were not without limitations.
  • the zinc atoms need to be activated so as to expose their action sites.
  • the activation of zinc ricinoleate is typically achieved by solubilizing the compound, a non-trivial matter.
  • the present invention provides a dryer cycle fabric softener sheet capable of not only removing malodor from laundered items but also neutralizing the odor on fabric while the fabric is being used or worn.
  • a dryer sheet in accordance with the present invention utilizes a malodor neutralizing agent, such as a metallic salt (e.g., zinc ricinoleate), in a dryer sheet and is very effective in controlling malodor.
  • a malodor neutralizing agent such as a metallic salt (e.g., zinc ricinoleate)
  • zinc ricinoleate is the malodor neutralizing agent.
  • Pure zinc ricinoleate is a waxy solid that is substantially insoluble in water.
  • a composition including zinc ricinoleate and a cationic softener on a non-woven substrate which provides a fabric softener dryer sheet that is not only good for softening fabrics, but is stable and effectively controls malodor.
  • a fabric softener dryer sheet in accordance with an embodiment of the present invention has an active agent comprising about 0.01% to about 3% by weight of zinc ricinoleate, about 1.0% to about 99.9% by weight of a cationic surfactant is a very effective product.
  • the present invention relates to a dryer sheet that is an effective antistatic and softener for fabric and importantly, comprises a malodor neutralizing agent, effective in controlling malodor, for use during tumble drying and is effective at neutralizing odor on fabric when the fabric is used or worn.
  • the dryer sheet comprises an active malodor neutralizing agent that is capable of reducing the level of undesirable malodors available for human perception or that is capable of otherwise decreasing the level to which malodors are perceived.
  • a malodor neutralizing agent may reduce perceptible malodors, such as, for example, chemically reacting with malodor molecules, complexing with malodor molecules, absorbing malodor molecules, encapsulating malodor molecules, and/or influencing the ability of human sensory receptors to perceive malodors (e.g., anosmia).
  • active malodor neutralizing agents suitable for use in accordance with an exemplary embodiment of the invention may combat malodors by chemically reacting or complexing with malodor molecules, by blocking human sensory reception sites that detect the presence of malodor, or by otherwise treating, blending, reacting, or counteracting malodors without increasing the perceived overall odor level in a particular environment.
  • metallic salts can be used effectively as the active malodor neutralizing agents.
  • malodor neutralizing agent may comprise a metallic salt, preferably a water-soluble zinc salt.
  • the metallic salt is at least one of zinc ricinoleate, zinc chloride, zinc gluconate, zinc lactate, zinc maleate, zinc salicylate, zinc sulfate, and mixtures thereof.
  • the metallic salt is zinc ricinoleate.
  • Zinc ricinoleate controls malodors selectively through a chemical binding of low molecular weight organic compounds containing the osmogene functional groups.
  • zinc ricinoleate generally has no effect on carbonylic groups, such as aldehydes and ketones, which comprise typical perfume and fragrance components.
  • zinc ricinoleate may stably complex with malodor molecules.
  • the mode by which zinc ricinoleate complexes with malodors is similar to and can be compared to the iron binding and transport of oxygen in hemoglobin — the zinc acts as a catalyst to bind the malodor molecules, complexing it with the fatty acid side chains of the zinc ricinoleate molecule.
  • the zinc ricinoleate neutralizes the malodors — that is, it reduces the level of undesirable malodors available for human perception.
  • zinc ricinoleate molecules complex with one or more malodor molecules, depending on the size and shape of the malodor molecule(s). Once the complex is formed, it is a stable complex, that is, the malodor molecule will not be released from the zinc ricinoleate.
  • the active malodor neutralizing agent is zinc ricinoleate, for example such as that commercially available under the trade name TegoSorb from Degussa Goldschmidt Chemical Corporation in Hopewell, Virginia, USA.
  • the zinc ricinoleate is an active agent used at a level of about 0.01% to about 5.0% by weight, preferably at a level of about 0.2% to about 1.0%.
  • the zinc atoms need to be activated so as to expose their action sites.
  • the activation of zinc ricinoleate is typically achieved by solubilizing the compound prior to deposition onto the non- woven substrate.
  • Some malodor neutralizing materials such as pure zinc ricinoleate, are waxy solids and the solubilization of zinc ricinoleate in the cationic surfactant is not an easy task. That said, once combined with a liquid cationic surfactant, the reaction sites on the zinc atoms are available to form bonds with nitrogen and sulfur atoms thereby bonding with the malodor.
  • the composition of the present invention comprises a cationic surfactant.
  • a cationic surfactant may be utilized.
  • useful cationic synthetic surfactants include any solid or semisolid linear alkyl, branched alkyl, hydroxyalkyl, oleyl alkyl, acyloxyalkyl, diamidoamine, imidazoline or diester quaternary ammonium compounds, silicone, or aminosilicone compounds.
  • the cationic surfactant in accordance with a preferred embodiment is at a level from about 1.0% to about 99.9% by weight, preferably about 90% to about 99% and most preferably at a level of about 97%.
  • the composition may comprise UV absorbers.
  • the compositions that comprise UV absorbers adhere onto the treated textiles and improve the light stability of the fibers and/or the light stability of the other formula components.
  • UV absorbers should be understood to mean organic substances (light filters) that are capable of absorbing ultraviolet rays and reemitting the absorbed energy in the form of longer-wave radiation, e.g. heat. Examples of compounds that have these desired properties are the compounds, active through non-radiative deactivation, and derivatives of benzophenone with substituents in the 2- and/or 4-position.
  • substituted benzotriazoles such as for example the water-soluble benzenesulfonic acid-3-(2H-benzotriazol-2-yl)-4- hydroxy-5-(methylpropyl)-monosodium salt (Cibafast ® H), acrylates phenyl- substituted in the 3-position (cinnamic acid derivatives), optionally with cyano groups in the 2-position, salicylates, organic Ni complexes and natural substances such as umbelliferone and the endogenous urocanic acid are suitable.
  • biphenyl derivatives and, above all, stilbene derivatives which are commercially available from Ciba as Tinosorb ® FD or Tinosorb ® FR.
  • UV-B absorbers mention can be made of 3-benzylidenecamphor and 3-benzylidene- norcamphor and derivatives thereof, e.g. 3-(4-methylbenzylidene)camphor, A- aminobenzoic acid derivatives, preferably 4 ⁇ (dimethylamino)benzoic acid 2- ethylhexyl ester, 4-(dimethylamino)benzoic acid 2-octyl ester, and 4-(dimethylamino)benzoic acid amyl ester; esters of cinnamic acid, preferably A- methoxycinnamic acid 2-ethylhexyl ester, 4-methoxycinnamic acid propyl ester, A- methoxycinnamic acid isoamyl ester, and 2-cyano-3,3-phenylcinnamic acid 2- ethylhexyl ester (Octocrylene); esters of salicylic acid, preferably sal
  • UV absorbers if used, are typically used in amounts ranging up to about 1.0% by weight.
  • compositions of the present invention may comprise grayness inhibitors.

  • water-soluble polyamides which comprise acidic groups are suitable for this purpose. It is also possible to use soluble starch preparations and starch products other than those mentioned above, for example degraded starch, aldehyde starches, etc. Polyvinylpyrrolidone can be used as well.
  • cellulose ethers such as carboxymethylcellulose (sodium salt), methylcellulose, hydroxyalkylcellulose and mixed ethers such as methylhydroxyethylcellulose, methylhydroxypropylcellulose, and methyl- carboxymethylcellulose.
  • Grayness Inhibitors if used, are typically used in amounts ranging up to about 1.0% by weight.
