This material  is also known as "amodimethicone". Although silicones  with a high number, e.g., greater than about 0.5 millimolar  equivalent of amine groups can be used, they are not  preferred because they can cause fabric yellowing.  Nonetheless, it is possible, although not preferred, to  incorporate additional silicones in the present compositions.  Nonlimiting examples of useful silicones include noncur› able silicones such as polydimethylsilicone, relatively high  molecular weight polyalkyleneoxide modified  polydimethylsilicone, amino and quaternary modified sili- The present invention may utilize silicone as a supple› mental fabric wrinkle control agent to impart an enhanced  lubricating property or increased gliding ability to fibers in  fabric, particularly clothing. Although silicones can be uti› lized as supplemental fabric wrinkle control agents, such  compounds are not desirable in the present compositions  because the compositions already contain low molecular  weight polyalkyleneoxide polysiloxanes. Thus, the present  compositions are preferably essentially free of, or free of,  additional silicone materials, except for the low molecular  weight polyalkyleneoxide polysiloxane surfactants  described hereinbefore. It is especially preferred that the  present compositions are essentially free of, or free of,  additional volatile silicone oil materials, other than the low  molecular weight polyalkyleneoxide polysiloxane surfac- tants.  Suitable methods for preparing these silicone materials  are described in U.S. Pat. Nos. 2,826,551 and 3,964,500.  Silicones useful in the present invention are also commer› cially available. Suitable examples include silicones offered  by Dow Corning Corporation and General Electric Com- pany.  Other useful silicone materials, include materials of the  formula:  The preferred silicones are polydimethyl siloxanes and  preferably those polydimethyl siloxanes having a viscosity  of from about 10 to about 1,000,000 centistokes at 25°  C.  Mixtures of volatile silicones and non-volatile polydimethyl  siloxanes are also preferred. Preferably, the silicones are  hydrophobic, non-irritating, non-toxic, and not otherwise  harmful when applied to fabric or when they come in contact  with human skin. Further, the silicones are compatible with  other components of the composition are chemically stable  under normal use and storage conditions and are capable of  being deposited on fabric.  The present invention may utilize a fiber lubricant to  impart a lubricating property or increased gliding ability to  fibers in fabric, particularly clothing. Not to be bound by  theory, it is believed that water and other alcoholic solvents  break or weaken the hydrogen bonds that hold the wrinkles,  thus the fabric lubricant facilitates the fibers to glide on one  another to further release the fibers from the wrinkle con› dition in wet or damp fabric. After the fabric is dried, a  residual fiber lubricant can provide lubricity to reduce the  tendency of fabric re-wrinkling.  i. Silicone Polymers  Each  R  group preferably is alkyl, hydroxy, or hydroxy› alkyl group, and mixtures thereof, having less than about 8,  preferably less than about 6 carbon atoms, more preferably,  each  R  group is methyl, ethyl, propyl, hydroxy group, and  mixtures thereof. Most preferably, each  R  group is methyl.  Aryl, alkylaryl and/or arylalkyl groups are not preferred.  Each A group which blocks the ends of the silicone chain is  hydrogen, methyl, methoxy, ethoxy, hydroxy, propoxy, and  mixtures thereof, preferably methyl q is preferably an inte› ger from about 7 to about 8,000.  The stable, aqueous compositions herein can further com› prise an effective amount of a supplemental fabric wrinkle  control agent, in addition to the low molecular weight  polyalkyleneoxide polysiloxanes described hereinbefore,  that will provide enhanced body, form and drape control or  smoothness to the fabrics treated with the present compo› sitions. Preferably, these agents will be selected from the  group consisting of fiber lubricants, shape retention  polymers, hydrophilic plasticizers, lithium salts, and mix› tures thereof.  a. Fiber Lubricants  The alkyl groups substituted on the siloxane chain  (R)  or at  the ends of the siloxane chains  (A)  can have any structure as  long as the resulting silicones remain fluid at room tempera› ture.  Thus one type of silicone that is useful in the composition  of the present invention is polyalkyl silicone with the  following structure:  When metallic salts are added to the composition of the  present invention as an odor control agent, they are typically  present at a level of from about 0.1  %  to an effective amount  to provide a saturated salt solution, preferably from about  0.2% to about 25%, more preferably from about 0.3% to  about 8%, still more preferably from about 0.4% to about  5% by weight of the usage composition.  3. Supplemental Fabric Wrinkle Control Agents  Non-limiting examples of silicones which are useful in  the present invention are: non-volatile silicone fluids such as  polydimethyl siloxane gums and fluids; volatile silicone  fluid which can be a cyclic silicone fluid of the formula  [(CH$_{3}$ ) 2  SiO]n where n ranges between about 3 to about 7,  preferably about 5, or a linear silicone polymer fluid having  the formula (CH$_{3}$ ) $_{3}$SiO[(CH$_{3}$ ) $_{2}$SiO]mSi(CH$_{3}$ ) 3  where m can  be  O  or greater and has an average value such that the  viscosity at 25°  C. of the silicone fluid is preferably about 5  centistokes or less.  cones and volatile silicones, and curable silicones such as  aminosilicones and hydroxysilicones. Preferred silicone  supplemental wrinkle control agents include polyalkyle› neoxide polysiloxanes having realtively high molecular  weights, for example, a molecular weight of greater than  about 1,000, preferably at least about 5,000, and more  preferably at least about 10,000. Many types of aminofunc› tional silicones also cause fabric yellowing and such sili- cones are not preferred.  and mercaptans, are components of many types of malodors,  e.g., food odors (garlic, onion), body/perspiration odor,  breath odor, etc. Low molecular weight amines are also  components of many malodors, e.g., food odors, body odors,  urine, etc.  Copper salts possess some malodor control abilities. See  U.S. Pat. No. 3,172,817, Leupold, et al., which discloses  deodorizing compositions for treating disposable articles,  comprising at least slightly water-soluble salts of  acylacetone, including copper salts and zinc salts, all of said  patents are incorporated herein by reference. Copper salts  also have some antimicrobial benefits. Specifically, cupric  abietate acts as a fungicide, copper acetate acts as a mildew  inhibitor, cupric chloride acts as a fungicide, copper lactate  acts as a fungicide, and copper sulfate acts as a germicide.
