FIELD OF THE INVENTION  
       [0001]     The invention relates to a soothing lotion, which cleanses, moisturizes and protects the skin and controls odor from feces and urine on skin. The invention also relates to a cloth comprising said lotion.  
       BACKGROUND OF THE INVENTION  
       [0002]     Baza Cleanse &amp; Protect® with Odor Control is a well-known cleansing lotion comprising dimethicone as a skin protectant. For easy application to the skin, the product is typically provided in spray bottles. However, due to the reverse thixotrophic property of the lotion, plugging of the nozzle of the spray bottle can be a re-occurring problem.  
         [0003]     It has now been found that it is possible to alter the recipe for the Baza Cleanse &amp; Protect® with Odor Control to provide a new lotion with good odor control having a lower viscosity, which does not cause plugging of the nozzle in spray bottles.  
         [0004]     It has also been found that the new lotion with lower viscosity may easily be incorporated in a cloth or wipe fabric. Lotions with higher viscosity may not be as easily incorporated into a cloth or wipe fabric.  
         [0005]     Sage Products, Inc. and Medline Industries, Inc. market disposable washcloths comprising dimethicone. The disposable washcloth from Sage Products, Inc. is known as Sage® Comfort™ Shield™ Perineal-Care Washcloths, which comprises 3% dimethicone in a rayon/polyester blend needle-punch cloth. The product from Medline Industries, Inc. is known as Aloetouch One-Step Total Perineal Care, which comprises 3.2% dimethicone in a thin non-needlepunch cloth of a rayon/polyester blend.  
         [0006]     It is well known in the industry, that rayon is blended with polyester to enhance absorption characteristics. A disadvantage of using a polyester/rayon blend can be that a cloth of a polyester/rayon blend comprising a cleansing lotion may tend to not release as much lotion to a surface during a cleansing event as a cloth comprised of 100% polyester.  
         [0007]     It has been found that the new lotion of the invention is particularly suitable for incorporation into cloths or wipe fabric for preparing products useful for cleaning the surface, in particular the skin of a living being, and for controlling the odor from feces and urine on the skin, and for further providing a protective barrier to the skin.  
         [0008]     In addition needle-punch cloth made of 100% polyester has been found to be particularly useful as it is capable of delivering twice as much lotion to the skin compared to the above mentioned polyester/rayon blended products, and is capable of maintaining comparable absorption characteristics.  
       SUMMARY OF THE INVENTION  
       [0009]     Accordingly, the present invention relates to a cleansing lotion in the form of an emulsion comprising 75-85% w/w water, one or more skin protectants, such as dimethicone, one or more cleansing agents, and one or more odor control agents where the viscosity of the lotion is below 50,000 centipoise (cps) when measured on a Brookfield Digital viscometer models DV-1+ and DV-11+ at a temperature of 25° C.±1° C., using spindle T-C at a speed of 1.5 rpm.  
         [0010]     The invention also relates to a cloth and a spray bottle comprising the new lotion. In particular the invention relates to a needle-punch, 100% polyester fiber cloth comprising the above mentioned lotion. 
     
    
     DETAILED DESCRIPTION OF THE INVENTION  
       [0011]     Baza Cleanse &amp; Protect® with Odor Control is a well-known cleansing lotion comprising dimethicone as a skin protectant agent.  
         [0012]     It has been found, that by lowering the amount of cetearyl alcohol from 3% w/w and in particular by lowering the amount of zinc ricinoleate from 1% w/w in the known product, a lotion in the form of a stable emulsion with a viscosity suitable for incorporation of the lotion into a cloth may be obtained.  
         [0013]     Surprisingly, it has been found that a good odor control may be achieved even when the amount of zinc ricinoleate is reduced considerably by the use of fragrances, such as Ordenone™. Ordenone™ is a fragrance available from Belle Aire Fragrances, Inc.  
         [0014]     Accordingly, the present invention relates to a cleansing lotion in the form of an emulsion comprising 75-85% w/w water, one or more skin protectants, such as dimethicone, one or more cleansing agents, and one or more odor control agents where the viscosity of the lotion is below 50,000 centipoise (cps) as measured on a Brookfield Digital viscometer models DV-1+ and DV-11+ at a temperature of 25° C.±1° C., using spindle T-C at a speed of 1.5 rpm.  
         [0015]     In a preferred embodiment of the invention, the cleansing lotion as above comprises zinc ricinoleate as an odor control agent and the amount of zinc ricinoleate in the lotion is below 1% w/w.  
         [0016]     According to one embodiment of the invention, the new lotion comprises water, one or more emulsifiers or emulsion stabilizers, one or more skin protectants, such as dimethicone, one or more humectants, one or more emollients, one or more skin conditioners, one or more cleansing agents, one or more odor control agents, one or more preservatives, and optionally one or more pH controlling agents, in the form of an emulsion, where the composition comprises zinc ricinoleate as an odor control agent and the zinc ricinoleate is present in an amount below 1% w/w.  
         [0017]     Suitably, the cleansing lotion of the invention comprises 75 to 85% w/w water, 3.0-5.5% w/w of one or more emulsifiers or emulsion stabilizers, 1-3% w/w of one or more skin protectants, such as dimethicone, 1-4% w/w of one or more humectants, 4-7% w/w of one or more emollients, 0.5-4% w/w of one or more skin conditioners, 1-3% w/w of one or more cleansing agents, 0.01-1.0% % w/w of one or more odor control agents, 0.42-0.8% w/w of one or more preservatives, and optionally one or more pH controlling agents. Preferably, the cleansing lotion as above comprises 1-3% w/w dimethicone.  
         [0018]     The cleansing lotion of the invention may comprise cetearyl alcohol and glyceryl stearate as emulsifiers or emulsion stabilizers, isopropyl palmitate and glycine soja (soybean oil) as emollients, glycerin and panthenol as humectants, sodium lauroyl lactylate and propylene glycol as cleansing agent, allantoin and tocopheryl acetate as skin conditioners, methylparaben, propylparaben and diazolidinyl urea as preservatives, zinc ricinoleate, Ordenone™ and fragrance as odor control agents, and citric acid as pH controlling agent.  
         [0019]     According to a preferred embodiment of the invention, the amount of cetearyl alcohol is below 3% w/w.  
         [0020]     In the new recipe the amount of diazolidinyl urea may be also increased from 0.15% w/w to for example 0.30% w/w, compared to Baza Cleanse &amp; Protect® with Odor Control.  
         [0021]     Suitably, the cleansing lotion of the invention comprises 0.005-0.9% w/w zinc ricinoleate, suitably 0.005-0.1% w/w zinc ricinoleate, more preferred 0.005-0.05% w/w zinc ricinoleate, and most preferred 0.01% w/w zinc ricinoleate.  
         [0022]     The lotion of the invention suitably comprises 0.1-0.5% w/w Ordenone™, preferably 0.1-0.3% w/w Ordenone™ or most preferred 0.2% w/w Ordenone™.  
         [0023]     Thus, according to one preferred embodiment of the invention, the cleansing lotion comprises 0.005-0.05 w/w zinc ricinoleate, 0.1-0.5% w/w Ordenone™ and optionally an additional fragrance. If present, the additional fragrance is present in an amount of 0.1-0.3% W/w.  
         [0024]     According to another preferred embodiment of the invention, the cleansing lotion comprises 0.005-0.05 w/w zinc ricinoleate, 0.1-0.3% w/w Ordenone™ and optionally an additional fragrance. If present, the additional fragrance is present in an amount of 0.1-0.3% w/w.  
         [0025]     Even more preferred, the cleansing solution comprises 0.01 w/w zinc ricinoleate, 0.2% w/w Ordenone™ and optionally an additional fragrance. If present, the additional fragrance is present in an amount of 0.2% w/w.  
         [0026]     The additional fragrance may suitably be Extra Fresh from Belle Aire Fragrances, Inc.  
         [0027]     In a most preferred embodiment of the invention the composition of the new lotion is as stated in example 1 below.  
         [0028]     With the cleansing lotion of the invention, plugging of the nozzles of the spray bottles containing the lotion may be avoided. An additional advantage of the lower viscosity of the new lotion is that it is particularly useful in allowing for easier impregnation of the lotion into the fiber-based cloths intended to be used as cleansing cloths.  
         [0029]     Thus the invention also relates to a spray bottle and a cloth comprising the new cleansing lotion as described above.  
         [0030]     The lotion of the invention may be incorporated into to the cloth by well known industrial processes for incorporation of emulsions into a cloth, e.g. by spraying, dipping, roller graver, etc.  
         [0031]     The cloth is suitably made from one single type of synthetic polymer fiber, e.g. polypropylene or polyester fibers. Preferably, the cloth is made from 100% w/w polyester fiber, and suitably the polyester is a poly(oxy-1,2-ethanediyloxycarbonyl-1,4-phenylenecarbonyl).  
         [0032]     The cloth may be a woven or non-woven cloth. Most preferred the cloth is a non-woven needle-punch cloth.  
         [0033]     In a preferred embodiment the cloth is a 100% polyester (e.g. a poly(oxy-1,2-ethanediyloxycarbonyl-1,4-phenylenecarbonyl), staple fiber, crimped, needle-punch cloth, with the dimensions approximately 6-7 inches×10-11 inches with a weight of 2.25-3.85 oz/sy, preferably 2.5 oz/sy (85 g/m 2 ) and comprising 20-40 g, preferably 25-35 g, or most preferred 30 g of the new cleansing lotion of the invention.  
         [0034]     Preferably the cloth is made from the 100% polyester fiber web, CS85PET-XX, CAS #25038-59-9 available from Sage Products, Inc.  
         [0035]     The above mentioned, needle-punch cloth made of 100% polyester has been found to be particularly useful as it is capable of delivering twice as much lotion to the skin compared to the above mentioned polyester/rayon blended products.  
         [0036]     The invention also relates to the use of the new cleansing lotion as described above for cleaning the surface, in particular the skin of a living being, and for controlling the odor from feces and urine on the skin, and for further providing a protective barrier to the skin.  
         [0037]     The invention also relates to the use of the cloth as described above for cleaning the surface, in particular the skin of a living being, and for controlling the odor from feces and urine on the skin, and for further providing a protective barrier to the skin.
